Hot Strip Mill Hot rolled coils ranging between 1.5mm to 23mm in thickness and widths of 750 to 1850mm through four furnaces, a 2-stand roughing mill, a 7-stand finishing mill and three coilers. Slabs are reheated to approximately 1250 ˚C depending on product, reduced in the roughing mill from 240mm to the required transfer bar
What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

The Pickling Process CSI's pickling line started up in late 1994, and typically processes two out of every three coils produced at the Hot Mill. Its primary function is to remove the thin layer of oxidized iron, or scale, that forms on the surface of the …
This complex process includes a few different metal forming techniques, like punching, coining, piercing, blanking, and bending, among others. Roll Forming. Roll forming involves bending a long strip of metal (usually coiled steel) that is passed through sets of rolls, with each performing an incremental part of the bend.

Prime quality stainless steel strips having trimmed edges are fed to the tubes mill. Strip passes through various sets of rollers fitted in mill as ...
Cold Rolled Steel Strip is produced, as the term suggests by the further rolling of strip produced by the hot strip mills. Prior to cold rolling, the mill scale has to be removed, normally by the Pickling Process which uses mechanical manipulation (around small diameter rolls) and acid to dissolve the surface scale.

Typically, back-up rolls in hot strip mills are equipped with sliding bearings and it is common to use a key that prevents relative motion between the conical sleeve and the roll shaft. The key groove causes deformation of the sleeve under load. This sleeve 'spring' is observed as rolling force variation, which causes systematic thickness ...

Batch-type hot rolling planning highly affects electricity costs in a steel plant, but previous research models seldom considered time-of-use (TOU) electricity pricing. Based on an analysis of the hot-rolling process and TOU electricity pricing, a batch-processing plan optimization model for hot rolling was established, using an objective function with the goal of …
Keywords: hot strip mill (HSM), finishing stands, mean flow stress (MFS), continuously variable crown (CVC), shear stress, bending. Introduction 1Predictive models are required to provide the bending set point for bending for the flatness control devices at rolling stands of finishing mill of Hot Strip Mill (HSM). A simple model for roll
Since the rolling process of hot strip mill is different from the cold rolling, to some extent, Shohet discriminant may relax the requirement of relative crown: where denote the entry and exit strip thickness, and separately stand for relative crown of entry and exit, is the strip width, and or 1.86.
G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 11.5.1 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic – ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap. For the roughing mill (reversible 4-high) both roll …

where (h_{{text{c}}}), (h) and (h^{prime }) are the thicknesses at the center, 40 mm on the left side and 40 mm on the right side of the strip, respectively.. As is shown in Fig. 2, the simplified diagram of the studied rolling process includes six finishing mills, and all finishing mills are HCW (high crown mill with work roll shifting) that only consists of back up rolls and …
Definition of Rolling process: Rolling is defined as a process to form metals where the metal strip is pressed by two or multiple rollers, thus the uniform thickness is formed. To do this, the temperature is essential. There are two types of processes. One …

In order to ensure the universality of calculating program, finishing stand is divided into different heat exchange area in strip temperature calculation according to equipment and process characteristic of most hot strip mills. The calculation flow chart is shown in Fig. 5.
•Roll-strip contact length L •Average strip width w –despite the fact that spreading, or an increase in width, may actually occur if edger mills are not used •Average true stress of the strip in the roll gap Y avg •Assumes no friction and thus predicts lower roll force than the actual value •Power per roll (SI units)= pFLN / 60,000 kW
