4 hi mill cold roll flow chart

Process Flow Chart Stelco Limited

The Pickled coils are cold rolled on 4 Hi AGC cold rolling mill to obtain the required thickness and annealed in HSD fired bell-type annealing furnace for bright annealing. In case of medium and high carbon coils, the process of rolling and intermediate annealing can be repeated to a number of times depending upon the final thickness to be obtained. These coils after final rolling are slitted

4 High Rolling Mill Element

Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used. This reduction in work roll diameter: Reduces overall separating force required for reductions; Reduces overall energy needed for reducing

Hot Strip Mill an overview ScienceDirect Topics

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 force and roll torque were available so the friction coefficient could be evaluated in

Cold Rolling Stainless Steel Tube Cold Rolled Stainless

Cold Rolling. Cold rolling is a metalworking process in which metal is deformed by passing it through rollers at a temperature below its recrystallization temperature. Cold rolling increases the yield strength and hardness of a metal by introducing defects into the metal's crystal structure. These defects prevent further slip and can reduce the grain size of the metal, resulting in Hall-Petch
