Tata Steel | Making of Steel

The hot metal is converted into steel through a steelmaking process called the LD process Flat Products: The steel is cast into slabs, which are then rolled into hot rolled coils in the Hot Strip Mill & Thin Slab Caster Some of the hot rolled coils are further rolled into cold rolled and galvanisedcoils in the Cold Rolling Mill Long Products:

Dynamic Model of the Hot Strip Rolling Mill Vibration ,

Feb 25, 2019· The vibration demolding of the crystallizer leads to slab thickness deviation in continuous casting process Therefore, in this paper, the dynamic model of the hot strip rolling mill vibration resulting from entry thickness deviation is proposed and its dynamic characteristics are studied First, the dynamic model of vertical vibration in the hot strip rolling mill is established based on .

Cold Rolled and Spheriodized Annealed Steel Strips ,

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

The Pickling Process - California Steel

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 steel at the temperatures employed during hot rolling

Introduction to Rolling Process

from the rolls, the process is called simple rolling 12 Hot and Cold Rolling Processes From metallurgical point of view, rolling process can be classified under two broad categories, namely (i) hot rolling and (ii) cold rolling 121 Hot rolling In hot rolling the material is rolled at a temperature higher than its recrystallization temperature

Rolling of Metals

•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
