Multipass Hot Rolling of Steels
Multipass Hot Rolling of Steels Multipass hot rolling is a general practice in the production of plates. An illustration of a plate mill, Fig. 1, is shown below to demonstrate how a series of processes are carried out to produce plates from steel slabs. Slabs are first reheated in a furnace, which reduces its deformation strength sufficiently ...

Rolling Mills: 6 Different Types of Rolling Mills [Images ...
· In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its crosssectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...

A simplified method to calculate the rolling force in hot ...
· It is well known that there are sharp peaks (friction hills) in the specific roll pressure curves predicted by Sims formula and Цeликoв formula which result in large errors for hot rolling. In this paper, a new specific roll pressure formula is derived from the NavierStokes equation (NS equation) by the hydrodynamics method (HM) with assumptions that strip materials take the ...
