PRODUCTION MANAGEMENT

Define production:• According to Elwood Butta “production is a process by

which goods or services are created”.• Production involves the step by step conversion of one

form of material into another through chemical or mechanical process with a view to enhance the utility of the product or services.

• “Production management deals with the decision making related to production

• process of that the resulting goods and service is produced according to specifications in the amounts and at the scheduled demanded and at minimum cost” – Elwood Butta.

Company Profile

• TCIL is today the largest indigenous producer of tin coated and tin free steel sheets in India, enjoying 35-40% market share and undoubtedly the industry leader for 85 years. The company exports about 20-25% of its production directly to end-users (can-makers) and its products are well accepted in the markets of SE Asia, Middle East and some developed countries in Europe.

Company History

• The company was incorporated in 1920 and the site chosen was Golmuri, Jamshedpur. The first steel plate of Tinplate gauge was rolled on 18th Dec 1922 at the Hot Dip Plant (HDP) producing Hot Dip Tinplate, from tin bars supplied by Tata Steel and this continued till 1979 albeit with capacity enhancements. For 50 years, TCIL thus almost single-handedly built up the Indian Tinplate Industry.

Manufacturing Facilities - Stages of Production

All tinplate originates as in the steel-making furnace (Tata Steel), where the proper chemistry for steel is obtained to meet the specific needs of the end user. All tin mill products start their production process in a Basic Oxygen Furnace (Tata Steel).

Clod Rolling Mill Complex

Hot Rolled Coil Manufacture Once the steel is produced, the continuous casting process transforms

molten steel into slabs in one continuous operation. Continuous casting is a highly energy- and cost-efficient process that produces a slab of excellent quality and consistency. Continuous casting methods are now used in virtually all carbon steel production facilities to produce products of consistent, high quality. Next, the slab goes into the Hot Strip Mill (HSM) of Tata Steel where its thickness is reduced and it is wound in a down coiler into coil form. This is where the Hot Rolled Coil (HRC) is procured as the basic raw material by TCIL from Tata Steel.

Electrolytic Tinplating Line

• The unique properties of tin provide a coating on the steel that protects the contents, while providing the steel with an attractive appearance, corrosion resistance and ease in bonding, welding and painting. Tin is applied to both sides of the black plate coil through an electrolytic process. The thickness of the tin coating (called coating weight) is dependent upon the end-use application. Typical applications for electrolytic tinplate include food and beverage containers, paint trays, battery tops and paint, varnish and aerosol cans.

Process Flow

Manufacturing Facilities - Packaging

• TCIL firmly believes that packaging plays a major role in delivering the product on, as is manufactured basis, taking in stride the vagaries of environmental variations and transportation hazards. Both Tinplate and TFS packs are being first packed with polycoated, waterproof paper and plastic paper. The two metallic side-jackets are protected by metallic side-angles at the corners to prevent transit damages to sheets. The whole packet is thereafter covered with a single top box jacket to prevent any seepage of water during transit.
