CHAPTER 1

INTRODUCTION

The industrial revolution led to the development of factories for large-scale

production, with consequent changes in society. Originally the factories were steam-powered,

but later transitioned to electricity once an electrical grid was developed. The mechanized

assembly line was introduced to assemble parts in a repeatable fashion, with individual

workers performing specific steps during the process. This led to significant increases in

efficiency, lowering the cost of the end process. Later automation was increasingly used to

replace human operators. This process has accelerated with the development of the computer

and the robot.

Industry in the sense of manufacturing became a key sector of production and labour

in European and North American countries during the Industrial Revolution, which upset

previous mercantile and feudal economies through many successive rapid advances in

technology, such as the steel and coal production. It is aided by technological advances, and

has continued to develop into new types and sectors to this day. Industrial countries then

assumed a capitalist economic policy. Railroads and steam-powered ships began speedily

establishing links with previously unreachable world markets, enabling private companies to

develop to then-unheard of size and wealth. Following the Industrial Revolution, perhaps a

third of the world's economic output is derived from manufacturing industries—more than

agriculture's share.

There are many other different kinds of industries, and often organized into different

classes or sectors by a variety of industrial classifications.

Industry classification systems used by the government commonly divide industry

into three sectors: agriculture, manufacturing, and services. The primary sector of industry is

agriculture, mining and raw material extraction. The secondary sector of industry is

manufacturing. The tertiary sector of industry is service production. Sometimes, one talks

about a quaternary sector of industry, consisting of intellectual services such as research and

development (R&D).

Industrial visit is a part of the engineering course, during which students visit

companies and get insight of on the internal working environment of the company. The

industrial visit also provides an insight on how companies work and also useful information

related to the practical aspects of the course which cannot be visualized in lectures. The

students get the opportunity to see the mechanisms which are used in the present day

industries by these kinds of field visits

As a part of our curriculum we visited 3 industries and undergo an inplant training on

an industrial plant. The factories visited are

Hindustan Machine Tools Limited, Kalamassery unit

CHAPTER 2

HMT Ltd, KALAMASSERY

2.1. HMT (India)

HMT, formerly Hindustan Machine Tools, is a state-owned manufacturing company

under the Ministry of Heavy Industries and Public Enterprises in India

Hindustan Machine Tools was incorporated in 1953 by the Government of India as a

machine tool manufacturing company, in 1977 it become a public limited company under the

name HMT Ltd. Over the years diversified into watches, tractors, printing machinery, metal

forming presses, die casting & plastic processing machinery, CNC systems & bearings. HMT

is headquartered at Bengaluru (Bangalore). Successful technology absorption in all product

groups through collaborations with world renowned manufacturers and further strengthened

by continuous in-house R&D. Today, HMT comprises six subsidiaries under the ambit of a

holding company, which also manages the tractors business directly.

HMT Limited took over Praga Tools Limited as one of its subsidiaries 1988. Praga

Tools Limited was established in May, 1943 as Praga Tools Corporation Limited to

manufacture machine tools with its head quarters at Secunderabad. It was renamed as Praga

Tools Limited in 1963. It is mainly involved in manufacture of machine tools including CNC

machines.

HMT Limited has 18 manufacturing units. The constituent subsidiaries are given

below while the holding company retains the tractors business group.

HMT’s tractor business commenced its operations in 1971 in technical collaboration

with M/s MOTOKOV, Czechoslovakia. HMT started the operation with the manufacture of

25 HP tractors at the manufacturing plant in Pinjore, Haryana state. Over the years, it has

developed tractors ranging from 25 HP to 75 HP.

B.Tech Mech Engg., University of Kerala

We visited the HMT Ltd, kalamassery unit’s Machine tool facility. The facility consist of

various machining equipments. We studied the working of the various machining

equipments. The HMT Ltd, kalamessry build machine that can weight upto 10 tonnes. The

various machines we saw in the unit are

Pattern making: - this facility is used by the HMT itself. In this facility the pattern of

the various machine tools are created. The HMT have a foundry and the machine tools are

molded in the foundry. The design of the tools is made in this pattern making facility. The

patterns are then transferred to the foundry and molding is done. The patterns are made of

clay. The property of the clay is improved by adding additives. The single pattern consist of

a number of tools because the size of the tools are small then is is easy that way. If the size is

very large the single mod patterns are used

Foundry: - It is a factory that produces metal castings. Metals are cast into shapes by

melting them into a liquid, pouring the metal in a mold, and removing the mold material or

casting after the metal has solidified as it cools. In metalworking, casting involves pouring

liquid metal into a mold, which contains a hollow cavity of the desired shape, and then

allowing it to cool and solidify. The solidified part is also known as a casting, which is

ejected or broken out of the mold to complete the process. Casting is most often used for

making complex shapes that would be difficult or uneconomical to make by other methods.

Fabrication: - It refers to building metal structures by cutting, bending, and

assembling. The cutting part of fabrication is via sawing, shearing, or chiseling (all with

manual and powered variants); torching with handheld torches (such as oxy-fuel torches or

plasma torches); and via CNC cutters (using a laser, torch, or water jet). The bending is via

hammering (manual or powered) or via press brakes and similar tools. The assembling

(joining of the pieces) is via welding, binding with adhesives, riveting, threaded fasteners, or

even yet more bending in the form of a crimped seam. Structural steel and sheet metal are the

usual starting materials for fabrication, along with the welding wire, flux, and fasteners that

will join the cut pieces. As with other manufacturing processes, both human labor and

automation are commonly used. The product resulting from (the process of) fabrication may

be called a fabrication. Shops that specialize in this type of metal work are called fab shops.

The end products of other common types of metalworking, such as machining, metal

stamping, forging, and casting, may be similar in shape and function, but those processes are

not classified as fabrication.

Conventional machining: - It is a form of subtractive manufacturing, in which a

collection of material-working processes utilizing power-driven machine tools, such as saws,

lathes, milling machines, and drill presses, are used with a sharp cutting tool to physically

remove material to achieve a desired geometry. Machining is a part of the manufacture of

many metal products, but it can also be used on materials such as wood, plastic, ceramic, and

composites. A person who specializes in machining is called a machinist. A room, building,

or company where machining is done is called a machine shop. Machining can be a business,

a hobby, or both. Much of modern day machining is carried out by computer numerical

control (CNC). Computers are used to control the movement and operation of mills, lathes,

and variety of other cutting machines.

Numerical control (NC): - It refers to the automation of machine tools that are

operated by abstractly programmed commands encoded on a storage medium, as opposed to

controlled manually via hand wheels or levers, or mechanically automated via cams alone.

The first NC machines were built in the 1940s and 1950s, based on existing tools that were

modified with motors that moved the controls to follow points fed into the system on

punched tape. These early servomechanisms were rapidly augmented with analog and digital

computers, creating the modern computer numerical control (CNC) machine tools that have

revolutionized the machining processes. In modern CNC systems, end-to-end component

design is highly automated using computer-aided design (CAD) and computer-aided

manufacturing (CAM) programs. The programs produce a computer file that is interpreted to

extract the commands needed to operate a particular machine via a postprocessor, and then

loaded into the CNC machines for production. Since any particular component might require

the use of a number of different tools-drills, saws, etc., modern machines often combine

multiple tools into a single "cell". In other cases, a number of different machines are used

with an external controller and human or robotic operators that move the component from

machine to machine. In either case, the complex series of steps needed to produce any part is

highly automated and produces a part that closely matches the original CAD design.

Lathe: - It is a machine tool which rotates the workpiece on its axis to perform various

operations such as cutting, sanding, knurling, drilling, or deformation with tools that are

applied to the workpiece to create an object which has symmetry about an axis of rotation.

Lathes are used in woodturning, metalworking, metal spinning, and glass-working. Lathes

can be used to shape pottery, the best-known design being the potter's wheel. Most suitably

6

Page 7: Report Vijeesh

B.Tech Mech Engg., University of Kerala

equipped metalworking lathes can also be used to produce most solids of revolution, plane

surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional

solids of incredible complexity. The material can be held in place by either one or two

centers, at least one of which can be moved horizontally to accommodate varying material

lengths. Other work-holding methods include clamping the work about the axis of rotation

using a chuck, or to a faceplate, using clamps or dogs.

Milling machine: - It is a machine tool used to machine solid materials. Milling

machines are often classed in two basic forms, horizontal and vertical, which refers to the

orientation of the main spindle. Both types range in size from small, bench-mounted devices

to room-sized machines. Unlike a drill press, which holds the workpiece stationary as the drill

moves axially to penetrate the material, milling machines also move the workpiece radially

against the rotating milling cutter, which cuts on its sides as well as its tip? Work piece and

cutter movement are precisely controlled to less than 0.001 in (0.025 mm), usually by means

of precision ground slides and lead screws or analogous technology. Milling machines may

be manually operated, mechanically automated, or digitally automated via computer

numerical control. Milling machines can perform a vast number of operations, from simple

(e.g., slot and keyway cutting, planing, drilling) to complex (e.g., contouring, die sinking).

Cutting fluid is often pumped to the cutting site to cool and lubricate the cut and to wash

away the resulting swarf.

Grinding machine: - It is often shortened to grinder, is a machine tool used for

grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain

of abrasive on the wheel's surface cuts a small chip from the workpiece via shear

deformation. Grinding is used to finish workpieces which must show high surface quality

(e.g., low surface roughness) and high accuracy of shape and dimension. As the accuracy in

dimensions in grinding is on the order of 0.000025mm, in most applications it tends to be a

finishing operation and removes comparatively little metal, about 0.25 to 0.50mm depth.

However, there are some roughing applications in which grinding removals high volumes of

metal quite rapidly. Thus grinding is a diverse field.

Planer: - It is a type of metalworking machine tool that uses linear relative motion

between the workpiece and a single-point cutting tool to machine a linear toolpath. Its cut is

analogous to that of a lathe, except that it is (archetypally) linear instead of helical. (Adding

axes of motion can yield helical toolpaths; see "Helical planing" below.) A planer is

7

Page 8: Report Vijeesh

B.Tech Mech Engg., University of Kerala

analogous to a shaper, but larger, and with the entire workpiece moving on a table beneath

the cutter, instead of the cutter riding a ram that moves above a stationary workpiece. The

table is moved back and forth on the bed beneath the cutting head either by mechanical

means, such as a rack and pinion drive or a lead screw, or by a hydraulic cylinder.

Heat treating: - It is a group of industrial and metalworking processes used to alter the

physical, and sometimes chemical, properties of a material. The most common application is

metallurgical. Heat treatments are also used in the manufacture of many other materials, such

as glass. Heat treatment involves the use of heating or chilling, normally to extreme

temperatures, to achieve a desired result such as hardening or softening of a material. Heat

treatment techniques include annealing, case hardening, precipitation strengthening,

tempering and quenching. It is noteworthy that while the term heat treatment applies only to

processes where the heating and cooling are done for the specific purpose of altering

properties intentionally, heating and cooling often occur incidentally during other

manufacturing processes such as hot forming or welding.

CHAPTER 4

TRAVANCORE TITANIUM PRODUCTS Ltd, TVM

4.1. TRAVANCORE TITANIUM PRODUCTS Ltd

Travancore Titanium Products Ltd (TTP), is the leading manufacturer of anatase

grade titanium dioxide in India. The company was incorporated in 1946 at

Thiruvananthapuram, the capital of Kerala, India on the initiative of Sir C.P.Ramaswamy

Iyer. The main product is pigment grade titanium dioxide which is extracted from ilmenite,

which is abundantly available as placer deposits on beaches near Kollam, 65 km north of

Thiruvananthapuram. Ilmenite, a mixture of titanium dioxide and iron in the form of

ferric/ferrous oxide, is treated with Sulphuric Acid to get Titanium dioxide and ferrous

sulphate.

The company was promoted by His Highness Chithira Tirunal Balaramavarma Maharaja, the

then ruler of the State of Travancore (now Kerala State in India) with the technical

collaboration of British Titan Products, (now Ti-oxide Group). Though the company was

registered in 1946, actual production was started only in 1952 with a small capacity of 5 t.p.a.

Later subsequent expansions were made in 1962 and 1973 and now TTP can produce about

20000 tones of titanium dioxide per annum.

In 1960 Government of Kerala took over the management of the Company. Now the

administrative control is vested with the Department of Industries, Government of Kerala.

The company also possesses a modern sulphuric acid plant which was commissioned in 1996,

for utilizing the tail gas recycling DCDA (Double Catalysis Double Absorption) technology.

An alkali scrubbing system is incorporated in the plant, and this in turn helps to keep sulphur

4.2. TECHNOLOGY/PROCESS

Travancore Titanium Products Limited is currently producing TiO2, antase grade,

through the sulphate route. Ilmenite, a mixed oxide of titanium, ferrous iron and ferric iron is

the main raw material for the production of titanium dioxide pigment. Ilmenite is reacted with

sulfuric acid in reinforced cement concrete tanks called Digesters, lined with lead and acid

resistant bricks. Exothermic reaction is initiated by the heat of dilution of the acid with water

and a porous cake is formed. The mass in the solid form is dissolved in dilute sulphuric acid

to get titanium in solution as titanium oxy sulphate (TiOSO4) along with other metallic

ingradients in ilmenite as their sulphate. The liquor is reduced using scrap iron, when the

ferric iron gets completely reduced to the ferrous state.

The resulting black liquor is clarified, concentrated and boiled by injecting steam to

precipitate the titanium content as hydrated titania. The hydrated titania is filtered over drum

type rotary vacuum filters. Any ferric iron still present is reduced to ferrous iron by leaching

the pulp with dilute sulphuric acid. It is washed free of iron and other impurities and calcined

in a rotary kiln is cooled in rotating coolers and de-agglomerated in pendulum mills to very

fine particles. The fine white powder is packed in 25kg HDPE bags.

Ilmenite + Sulphuric Acid => Titanyl Sulphate => Hydrated Titanium Dioxide

=> Titanium Dioxide

4.3. PRODUCTS

Titanium Dioxide is the whitest of white pigments and has replaced other less

effective pigments such as Zinc Oxide, Lithopone etc. This is because of the unique

combination of its superior properties of a high refractive index, low specific gravity, high

hiding power and opacity,and non-toxicity. It also has high tinting strength and dispersion

properties as well as chemical stability. Titanium Dioxide is produced in TTP in the

ANATASE form and marketed as AJANTOX Anatase grade possesses excellent water

dispersion properties and gives a clear tone in all ranges of application.

Travancore Titanium Products Limited has recently launched a Rutile Grade Titanium

dioxide pigment viz., TTP RD-01. This product was developed in the year 2002 indigenously

through the Sulphate route. TTP markets this product without surface treatment at a very

competitive price.

CHAPTER 5

TRAVANCORE COCHIN CHEMICALS Ltd, KOCHI

5.1. TCC Ltd, KOCHI

The Travancore-Cochin Chemicals Ltd., popularly knows as TCC was established in

1950. The idea of establishing the unit was conceived by M/s Sheshasayee Brothers the then

Managing Agents of FACT. The venture was started as partnership concern in the name

Travancore Mettur Chemicals with FACT and MCIC (Mettur Chemicals and Industrial

Corporation) as partners. In 1951 the partnership was registered as a Public Limited

Company, with the State Government contributing the major share of equity and the company

was then named as TRAVANCORE-COCHIN CHEMICALS LTD. M/s Sheshasayee

Brothers continued to be the managing agents for the next 10 years.

Commercial production of Caustic Soda from the first plant of 20 tpd capacity was started in

1954 January. TCC is the first unit in India to manufacture Rayon grade Caustic Soda.

5.2. STAGES OF GROWTH

At present total installed capacity is 175 tpd Caustic Fusion plant for 100 tpd. The company

produces Rayon grade caustic soda using Membrane cell Technology. The main raw

materials are common salt (NaCl) electricity and water. Company has three running plants

which are membrane plant, CCF plant and Soda bleach plant.

5.3. TECHNOLOGY/PROCESS DESCRIPTION

5.3.1. Membrane cell technology

It employs Ion exchange membrane placed between coated Titanium

anode and coated Copper cathode. It requires lower current consumption and is an

environment friendly technology. However the caustic soda lye thus produces is of low

concentration-(32%) compares to the Caustic Soda production in mercury, and the major part

of it is to be further concentrated to 48-50% for use of consuming industries.

The membrane cell technology use the following steps to produce the caustic soda they are

described below

Brine saturation and purification

Electrolysis

Lean brine dechlorination

HCl Synthesis

Chlorine liquefaction

The chloralkali process is an industrial process for the electrolysis of sodium chloride

solution (brine). Depending on the method several products beside hydrogen can be

produced. If the products are separated, chlorine and sodium hydroxide (caustic soda) are the

products; by mixing, sodium hypochlorite or sodium chlorates are produced, depending on

the temperature. Higher temperatures are needed for the production of sodium chlorate

instead of sodium hypochlorite. Industrial scale production began in 1892.

24

When using calcium chloride or potassium chloride, the products contain calcium or

potassium instead of sodium.

The process has a high energy consumption, for example over 4 billion kWh per year in West

Germany 1985, and produces equal (molar) amounts of chlorine and sodium hydroxide,

which makes it necessary to find a use for the product for which there is less demand, usually

the chlorine.

There are three production methods in use. While the mercury cell method produces chlorine-

free sodium hydroxide, the use of several tonnes of mercury leads to serious environmental

problems. In normal production cycle a few hundred pounds of mercury per year are emitted

which accumulate in the environment. Additionally, the chlorine and sodium hydroxide

produced via the mercury-cell chloralkali process are themselves contaminated with trace

amounts of mercury. The membrane and diaphragm method use no mercury, but the sodium

hydroxide contains chlorine which has to be removed.

The most common chloralkali process involves the electrolysis of aqueous sodium

chloride brine) in a membrane cell.

Saturated brine is passed into the first chamber of the cell where the chloride ions are

oxidised at the anode to chlorine:

2Cl– → Cl2 + 2e–

At the cathode, hydrogen in the water is reduced to hydrogen gas, releasing hydroxide ions

into the solution (C in figure):

2H2O + 2e– → H2 + 2OH–

The non-permeable ion exchange membrane at the center of the cell allows the sodium ions

(Na+) to pass to the second chamber where they react with the hydroxide ions to produce

caustic soda (NaOH) (B in figure). The overall reaction for the electrolysis of brine is thus:

2NaCl + 2H2O → Cl2 + H2 + 2NaOH

25

Page 26: Report Vijeesh

B.Tech Mech Engg., University of Kerala

A membrane cell is used to prevent the reaction between the chlorine and hydroxide ions. If

this reaction were to occur the chlorine would be disproportionated to form chloride and

hypochlorite ions:

Cl2 + 2OH– → Cl– + ClO– + H2O

Above about 60°C, chlorate can be formed:

3Cl2 + 6OH– → 5Cl– + ClO3– + 3H2O

Because of the corrosive nature of chlorine production, the anode has to be made from a non-

reactive metal such as titanium, whereas the cathode can be made from Nickel.

In the membrane cell, the anode and cathode are separated by an ion-permeable membrane.

Saturated brine is fed to the compartment with the anode (the anolyte). A DC current is

passed through the cell and the NaCl splits into its constituent components. The membrane

passes Na+ ions to the cathode compartment (catholyte), where it forms sodium hydroxide in

solution. The membrane allows only positive ions to pass through to prevent the chlorine

from mixing with the sodium hydroxide. The chloride ions are oxidised to chlorine gas at the

anode, which is collected, purified and stored. Hydrogen gas and Hydroxide ions are formed

at the cathode.

CHAPTER 6

CONCLUSION

This seminar includes all the Industrial Visits and Industrial Training I had undergone

during this course. These industrial visits were done as a part of curricular activities. The

selection of apt industries was a difficult task and more over availing there permission was a

tedious job also.

Industrial visits and training enabled the familiarization of real working environment.

The industrial visits were a kind of stepping out from a theoretical world of books to the

practical world. These visits also enabled to create awareness to the need of harmony at work.

The essence of industrial morale and other disciplines in industries were also understood.
