The article presents results obtained in the study of slab deformation process in the roughing stands of Severstal's Mill-2000 hot-rolling line. The implementation of a rolling process model based on the use of the DEFORM-3D software package for predicting the displacement of metal from the edges of the slab to the middle of the workpiece width is described. The convergence of the modeling ...

then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process. The Hot Mill rolls slabs weighing up to 30 tons between 30" and 74". Steel slab 8 to 9 inches thick and up to 36
On the basis of proceedings of an international symposium on casting and rolling complexes the latest solutions for hot-rolled strip production by a combined process of continuous thin slab casting and rolling are reviewed. Advanced developments in the field of equipment and technologies are presented. The main tendencies and future tasks on this subject are noted.
Slabs. Slabs are semi-finished steel and are the end result of rolling ingots on a rolling mill or by processing them through a continuous casting process. Slabs will have rectangular cross sections and are used as the "starter" metals in the making of flat products such as steel plates or hot rolled coils.

1. Introduction. Strip breakages in steel rolling mills result in loss of production due to mill stoppage and may also cause damage to equipment. The magnitude of loss is even higher in the case of integrated processes like Thin Slab Casting and Rolling (TSCR) where all the processing stations are interlinked .In such a case, mill stoppages may affect upstream processes and can also lead to ...
A slab is a length of metal that is rectangular in cross-section. The slab is created directly by continuous casting or indirectly by rolling an ingot on a slabbing mill. Slabs are usually further processed via flat rolling, skelping, and pipe rolling. Common final products include …
The slab will be delivered to the rolling mill by a new tunnel furnace via a swiveltype ferry system. The layout - allows for the installation of the new caster and first portion of the tunnel furnace and swivel system without affecting the mill's production. Furthermore, two new roughing mills will be added to expand rolling capabilities.
Thin-slab casting and rolling processes are well known and have been in continuous development since their introduction at the end of the last cen-tury. In an attempt to find the optimum configura-tion to be able to economically operate and fully load the rolling mill, several different concepts have emerged that include up to three casting ...
Rolling mills. Rolling mill consists of rolls, bearings, structure, or housing for rigidly supporting these parts, power drive, power transmission system, speed control, roll gap adjusting set up, etc. The force for rolling generally is very high. The power requirements are very high. Hence initial capital investment is high.
The final result of rolling ingots in a rolling mill, Steel Slab is defined as a semi-finished steel product which sometimes, is produced by processing ingots using a continuous casting process. With rectangular cross-sections, steel slabs are used as …
Before slabs can be rolled into hot rolling mills, slabs should be heated to the deformation temperature using reheating furnaces. Achieving this heating temperature is a major constraint of this ...
Slab is a rectangular product with thickness varies fr om 50 to 300 nun and width from 500 to 1800 nun or even more. Slabs are rolled from ingots either in a Blooming or Slabbing mill. Slab is an initial material for rolling of flat products.

without cold rolling this portion is quite limited. Arvedi ESP (endless strip production) technology, featuring the direct linking of a slab caster and hot-rolling mill in a continuous, uninterrupted production line, is providing new impulses for the flat-steel market. With this game-changing technology,
Remedy- Proper soaking of slabs. E. Mechanical Defect due to Mill (MDM) Any significant deep impression over the slab surface will create MDM defect over the plate in the process of rolling. The deep impression may be present on the slab or is generated in the process of charging, discharging or the rolling of the slab. It appears on
ROLLING MILL SLAB GUIDE . United States Patent 3648507 . Abstract: The disclosure of this invention relates to an adjustable side guide for a rolling mill adapted to guide a slab or plate as it passes over a roller table. The guide includes a guiding head for engaging the edge of the slab or plate.
In Vario rolling mills, induction heating is used after the first roll stand. This is an innovative technology for production of micro-alloy steel grades in API quality or better. Induction heating ensures a uniform temperature level between the first rolling mill …
Vertical rolling is an important technique used to control the width of continuous casting slabs in the hot-rolling field. Accurate prediction of vertical rolling force is a core point maintaining rolling-mill equipment. Owing to the limitation of the algorithm in use, the prediction accuracy of most vertical rolling force models based on the energy method can only reach more than 10% ...
