cold roll mill function

J.F. Cameron, C.G. Clayton, in Radioisotope Instruments, 1971 Cold-strip reduction mills. A tandem cold rolling mill usually consists of three to five stands of rollers, each of which reduces the strip thickness by about 20 to 40% so that the total reduction in one pass may be by a factor ten.. It has long been recognized that some, if not most, of the variations in thickness of strip produced ...

The Differences Between Hot and Cold Rolled Steel

Apr 04, 2018 NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000 F.
Mathematical model for cold rolling and temper rolling

A mathematical model for cold rolling and temper rolling process of thin steel strip has been developed using the influence function method. By solving the equations describing roll gap phenomena in a unique procedure and considering more influence factors, the model offers significant improvements in accuracy, robustness and generality of the solution for the thin strip cold and temper ...

The Function Of Cooling Water In Cold Rolling Mills

Or what is the role of cooling water for cold rolling mills? For this questions, the technical staff of Gongyi Jindi Metallurgical Equipment Co., Ltd will explain to you one by one: 1) Reducing the surface temperature of the roller and the thermal impact of the rolled material on the roller surface, and the occurrence of cracks; 2) It is possible to reduce the temperature difference between the inside and outside of the roller, reduce the thermal stress of the roller, and prevent the roller ...
Design and function of CVC rolls as a flatness actuator in

cold rolling mill is of the type where shifting of both first intermediate and inner second intermediate rolls are possible. The rolls are numbered and defined as: 1. Work roll, diameter between 50-75 mm. 2. First intermediate roll (tapered), diameter between 90-105 mm. 3. Inner second intermediate roll (CVC roll), diameter between 177-182 mm. 4.
