The Minimill lay-out is one of the decisive factors in fulfilling the project requirements. Consequently both the annual productivity target and the actual production mix have an impact on the plant lay-out configuration. Optimization of the following production routes has been also taken in consideration.

The proposed solution is shown on the attached preliminary layout drawing No. ML.12.001.01.0.




1.2 Steel Making Plant highlights

1.2.1 Scrap Yard

The covered scrap yard will be designed with one single bay. The bay will be equipped with rails for scrap bucket car and two cranes, each one with 20 t lifting capacity. Both cranes can use either grabs or magnets for bucket filling. The scrap bucket car is of an electro-mechanical driven type with weighing device.

External access will be provided for unloading of trucks delivering scrap from open storage area. Autonomy of scrap bay area: 1 week Autonomy of open storage area: 1 month




1.2.2 Electric Arc Furnace

The main features of the proposed furnace are as follows: Furnace type AC Tap weight 40 t Hot heel size 5 t Charge type 100% scrap or 70% scrap / 30% Cold DRI Charging practice two scrap bucket charging Transformer apparent power 30 MVA + 20% Serial reactor air-core type Electrode diameter 460 mm (18”) Electrode regulation digital-hydraulic type (SMS Concast) Shell design EBT type Lower shell steel plate Upper shell water-cooled panels (steel + Cu) Arms design conductive (copper) Alternative energy combined injectors (CONSO)

Additional EAF equipment will be arranged as follows: Manual sampling and temperature measuring device (introduced through slag door). Electrode jointing station.




The furnace will be equipped with coherent flame CONSO injectors, which will supply additional chemical energy required for charge melting and superheating. Totally three (3) CONSO units will be installed on the furnace (2 wall-mounted injectors and 1 EBT injector). Each CONSO injector can work as oxy-gas burner or oxygen lance. The installed burner power will be up to 1.6 MW per unit.

The injectors used in the lancing mode are designed to operate with the oxygen flows of 800 – 1,200 Nm3/h (pre-lance mode with subsonic oxygen injection) and 1,700 – 2,500 Nm3/h (supersonic oxygen injection).

All injectors are of the same design: one CONSO injector will be installed on the EBT balcony; two injectors will be mounted on the furnace shell walls. Wall-mounted injectors are to be used as burners and lances, while the EBT injector is foreseen to operate mainly as burner. The injectors are installed inside of water-cooled boxes, which are fixed in the upper shell water-cooled panels.




In order to protect the slag line refractories against erosion during oxygen injection, special cooling blocks are integrated with injector water box. The cooling blocks consist of thin copper fins that allow for extensive heat exchange and effective cooling of the refractory material below the water-cooled panels at the slag line level. The copper fins are cooled by contact with the surface of the water box. Details of CONSO injector inside wall-mounted water box are shown below.

In addition to gas/oxygen injectors, the EAF will be equipped with one (1) carbon injection tuyeres. The tuyeres are located below the wall injectors. The installation angles and directions of the carbon tuyeres are selected to secure intersection of the oxygen and carbon jets inside the slag volume at the interface with liquid bath. Each tuyere will be independently fed from a dedicated carbon dispenser. The typical carbon injection rate is in the range of 0 – 60 kg/min. Each carbon injection tuyere will be fed from a separate dispenser. The drawing below indicates the preliminary arrangement of all foreseen gas & oxygen as well as carbon injection equipment.




The individual location of the injectors has been selected with a consideration of the following targets to be achieved: Optimum balance between cold and hot spots inside the furnace and uniform charge melting. Minimization of the splashing phenomena during supersonic oxygen injection. Increased yield of carbon monoxide post-combustion above the slag level. Reduction of electrode consumption caused by excessive oxidation during oxygen lancing. The CONSO injection equipment will be connected to a special valve regulation stand. Each injector will be supplied from independent lines: Natural gas for burner and lance oxygen jet shielding. Oxygen for burner flame and oxygen lance shielding. Subsonic and supersonic oxygen lancing.




Operation of the complete CONSO system is controlled by the automation system. Injection program is normally executed automatically in accordance with the melting profile. Each injector can also be operated manually by the furnace operator. Different melting recipes can be created in function of the melting behavior of furnace charge: each melting recipe controls changes of the several melting parameters such as electric energy input (transformer voltage tap and current curve settings as well as reactor position selector), alternative energy control (on/off events, flame type and media flow settings), carbon injection set points, off-gas system operation (furnace pressure and fan capacity) as well as addition management (material selection, on/off events and quantity/flow set points).




Productivity calculation for EAF Based on the considerations regarding the utilization of the available electrical and alternative melting energy as well as characteristics of the charge and its design, the likely furnace operation have been simulated with the details and results presented in the next pages. Using the recommended operational profile, the furnace can operate within the time frames specified in the table below:

1.3 Rolling mill highlights

1.3.1 General Arrangement

The mill is rated for a nominal capacity of 300,000 t/y rebars , according to the product mix. In future will be possible o install a wire rod line additionally. The mill itself is installed at level of +/- 0,0 mm above ground floor with pass-line + 900 mm above ground level. However, the billet storage, as well as the finished product storage, are located at ground level.

1.3.2 Rolling Speeds

The considered distance between dividing shear and cooling bed, as well as the length of cooling bed, make possible that the rolling speeds, according to the rolling schedules, can be realized. Rolling speed Rebars on cooling bed: 36 m/s max. for dia. 8 mm




ROLLING MILL PRODUCTION STUDY







1.3.3 Equipment in Front and Behind the Reheating Furnace for Billets

The cold billets will be deposited on the charging grid in layers by the overhead crane and one by one transported to the furnace charging roller table. The furnace charging roller table also transports the hot billets from the continuous casting machine, through one approach roller table to feed one hot billet at a time to the furnace. After weighing the charging roller table feeds the billets to the reheating furnace. Billets which have to be rejected will be ejected by means of levers into a table for reject billets, positioned after weighing device. The. furnace reheats the billets up to the pre-selected discharging temperature. The pinch roll unit are arranged at the discharging side of the reheating furnace. Due to the roller table length, heated billets can be discharged from this roller in emergency case by an ejecting device. The billet entering in mill stand No. 1 will be supported by a pinch roll set arranged in front of this stand. Reject billet deposited by crane onto a rail car positioned at floor level + - 0.00 A different phase is represented by the possibility to install an induction furnace in front of the reheating furnace. By this will be possible to bypass the Gas reheating furnace for hot charging.

A box pass sequence for 130 mm square initial billet size is provided for the first stands of the roughing mill which allows billet entry in the first stand in flat position, followed by a box-box and oval-round sequence for the remaining roughing mill, the intermediate and finishing mill. This pass design ensures the high demands on surface quality and tolerances and is a common design for the entire product range. In spite of the big dimension range the pass sequence is designed in order to keep as much as possible the basic pass sequence.




1.3.5 Continuous Rolling Mill

The continuous rolling mill comprises a suitable number of housingless stands respectively installed in horizontal/vertical configuration. Roughing Mill The roughing mill consists of housingless stands in horizontal-vertical arrangement with multi-groove rolls. The pass sequence is largely the same of the complete dimension range which means that roll changing is mostly required in case of worn grooves. These stands are of all of the same type and interchangeable. Intermediate/Finishing Mill The intermediate/finishing mill consists of multi-groove housingless stands in horizontal, vertical arrangement. The stand sizes are all of the same type and interchangeable. The housingless stands are featuring high mill stand stiffness and have been in operation with top results in a large number of rolling mills.

Main features of the housingless stands of cartridge type are:

• Symmetrical roll adjustment (fixed rolling line) • High flexibility of utilization (same stand in horizontal and vertical configuration) • High reliability (very close force distribution with very limited elongation) • Quick rolls change by special robot devices All stands of the mill are shiftable over the full barrel length under the action of a hydraulic cylinder. Additionally this cylinder can move the stand from pass-line. For rolling small products loop control will be applied in the finishing mill for tension free rolling to achieve close tolerances. In the roughing mill and intermediate mill where bigger sections will be rolled tension control will be applied by the current comparison method.




Roll Changing The roll changing will be realized out-of line in a separate roll shop area. In case of necessary roll changing the complete stand will be shifted out of pass line by means of a hydraulic cylinder and transported to the stand preparation area in the roll shop by Customer EOT-crane respectively transfer car. After roll changing the new stand will be pulled into the pass line by the same hydraulic cylinder. Change stands are recommendable for rolls/product changing operation in short time. The stand preparation area consists of a tilting device for turning vertical stands into horizontal position and vice versa as well as robots for changing worn rolls against new ones.




1.3.6 Shears in the Mill

Downstream the roughing and intermediate mill a start-stop shear is provided for nose cropping, as well as chopping into scrap pieces in emergency case. These shears are equipped with a scrap chute and scrap bucket.

1.3.7 Thermoprocessing System

Thermoprocessing lines are arranged behind the last finishing stands. The thermoprocessing will be used for direct quenching and tempering of rebars to improve the metallurgical properties. At the entrance of the thermoprocessing system a trimming shear for optimization is installed




1.3.8 Finishing Block

Bar stock feeding line to finishing block A stock feedline line with a water cooling box is arranged between the last finishing stand of the finishing block. The stock is cooled down by means of a water box installed upstream of the finishing block. The rolled stock is guided in troughs with easily removable covers between the finishing stand and nose/cobble shear upstream the finishing block. A looper is arranged upstream the finishing block as well as a snap shear.. A nose/cobble shear is fitted at the finishing block entry side, the bar head is automatically cropped and scrapped in case of trouble in the finishing mill area. A pneumatic operated switch is arranged at back of the shear, combined with scrap buckets.

8 Stands Finishing Block Finishing block with 8 stands is proposed as finishing mill.




1.3.9 High Speed Delivery (H.S.D.®) System

High Speed Delivery System (H.S.D.® System) At cooling bed entry side, the bar (rebar dia. 8 to 32 mm dia.) is received by two

rotating channels at a max. speed of 36 m/s.

Pinch roll units A pinch roll unit with parallel axis is installed at the dividing shear entry side. Low/high speed rotating shears A rotating shear with direct drive is designed to cut-to-length the bars coming either

from the finishing stand and from the finishing block. The correct drum of the rotating

channel is chosen by a bar deviator.

Pipe conveyors Set of split type pipe conveyors are installed between the cut-to-length group and the

bar braking devices to deliver the bars to the rotating channel.

Bar braking devices Two bar braking devices with parallel axis are installed at rotating channel entry side

and are used for forced deceleration of the single bars.

Double rotating channel One double rotating channel (total of two drums) is designed to discharge the bars onto the cooling bed. The rotating channel arranged above the cooling bed entry side is supported by steel structure column.







1.3.10 Cooling Bed

A rake-type cooling bed designed for the following technical data is used for bar cooling: cooling bed length : 66 m cooling bed width (CL run-in to CL run-out roller table) approx. : 6,5 m approx. A slide system is provided to synchronies the bars coming from the rotating channels. The rake notches are arranged at 65 mm pitches and the rake stroke conforms to that pitch. The first part of the cooling area is a straightening plate grid giving additional support to

the material in the high-temperature area to thereby ensure material straightness due

to slow and uniform cooling

An aligning device comprising continuously operating driven and idling rolls is proposed to be arranged on the cold side of the rake-type cooling area. It rolls are profiled in conformity with the rake notch profile. This aligning device will be used to align the bar ends which results in an essential reduction of crop length losses when cutting into finishing lengths Arranged in extension of the rake position there is a carry off chain system which collects the bars coming from the rake-type cooling area in layers and which transfers these layers on a discharging roller table to the cold shear. The size of the layers is handled by the capacity of cold shear The drive of rake-system is provided in that manner that the drive can operate in a continuous motion as well as an interval motion For diagrams showing the final temperatures of the cooled bars please refer to the cooling diagrams Under consideration of the cutting length optimization on cooling bed the rolled bar will be cut in multiple finished lengths which can deviate from each other if necessary.







1.3.11 Cutting Equipment

For cutting the cooling bed layer into finished length we have provided one cold shear group. The cold shear cuts the layer of 60 m coming from the cooling bed into the final commercial length of 6 m and 12 m.

1.3.12 Bundling, Tying and Storing Equipment

Chain transfer conveys the bars from the rotating channel to the bundling area and discharge them into a pocket by means of movable cradles. Finally, a collecting table temporarily stores the bundles for final transfer to storage or shipping via overhead crane of fork lift.




1.4 Electrical & Automation System

SMS know-how covers the complete minimill production starting at the incoming power distribution, including speed control of all equipment, determination and selection of motor drives, selection of measuring equipment, programming of the basic logic control for all equipment, programming of various types of SCADA systems up to integration of plant control systems. For this purpose SMS has developed a complete solution including tools and functionalities for:

• Control and monitoring of the process • Control and optimization of the technological process parameters • Process scheduling and coordination The SMS Concast automation concept can be divided in:

• Basic Automation System (Level 1) • Process Control System (Level 2)




1.4.1 Basic Automation System – Level 1

The Basic Automation System consists of:

• Programmable Logic Controllers (PLC) • PC-based HMI (Human Machine Interface) graphical workstations • Control stations such as pulpits, desks or panels

The PLC system performs sequential, process, drive and motion control of the plant utilizing different type of controllers, various communication networks and interfaces. All components are carefully selected according to load conditions and requested performances. All electrical and instrumentation devices of the plant are connected to the I/O modules of the PLC. The amount of the required I/O’s is depending on the number of drives and instrumentation equipment and the quantity of consumers.




The HMI system is based on PC-based workstations running dedicated graphical SCADA applications. The workstations are located in the various control rooms of the plant, giving to the operators an exhaustive control over the equipment. The HMI’s read data from PLC’s, analyzing and displaying in graphical format all the related information. Furthermore the system is able to detect, display, and log alarms and events. Alarms and events are recorded on disk, thus allowing the review of data in order to determine potential causes and preventing them from occurring again.




Typical HMI screens (for reference only)




Control pulpits are used to directly control the machine running operation. The control pulpits are located in strategic position to allow good visibility for manual sequencing of operations and testing purposes.

Typical Control Stations (for reference only)




1.4.2 Process Control System – Level 2

The SMS Process Control System implements process control philosophies, production strategies and metallurgical models developed by SMS, combining state-of-the-art technical solutions with an awareness of the real needs in the modern production plants. The operator is provided with a transparent interface to the process management by a uniquely developed graphical windows based operator and data reporting interface combined with SMS in-house programs performing tasks such as data gathering from Level 1 PLC’s and other plants and on-line quality analyses / process optimization. The software programs and tools used to develop and run the system are the latest state of the art windows based programs, which are used by SMS to provide a professional and modern windows style program. Level 2 software is complete with Graphical User Interface with iconized menus, pull down selection boxes, on-line help, operator guidance messages and other useful features.

Typical Level 2 screens (for reference only)

Additionally, Process Control System is provided without loss of system security and with independence of operation from the Level 1 Control System. The Level 1 system can be selected to operate independently and can continue to operate in a fully automatic manner even in case of failure of the Level 2 system. Should this occurs, the automation system will warn the fault condition and automatically switch to Level 1 only mode. The Process Control System is based on the following design concepts: Relational database: all data is handled using a market-standard relational database system with SQL access for data storage and retrieval. Client/Server architecture: the information is typically hosted and processed on a central server while user-interface applications run on the peripheral clients. Distributed architecture: the system is accessible from a set of computers that are physically located near to the intended users, with access to the data on the central server via an Ethernet-standard network. Server reliability: the central server is characterized by a hard disk configuration that assures a high degree of reliability. State-of-the-art interface: the user interface of all Level 2 applications is designed using the latest graphical approaches to user-interfacing and, above all, with the real needs of the steel plant users in mind.
