· The present investigation devices a novel Xtype sixhigh (X6h) mill. In addition, parametric models of different roll layouts such as the fourhigh (4h), Itype sixhigh (I6h), and X6h mills are established. Threedimensional (3D) finite element (FE) contact analysis for a strip rolling process is conducted when the mills are subjected to a constant vertical load of 65 kN.
A large variation of configurations are possible in this process. An example of a modern cold rolling mill, for aluminum, is shown in Figure The mill is sixhigh; having two small diameter work rolls of 470 mm diameter and two sets of backup rolls. The diameter of the intermediate backup roll is 510 mm and the third backup roll is of 1300 ...
The horizontal force acting on a work roll was examined. This force results from the contact force between the work roll and backup roll in a backuprolldrive 4high coldrolling mill.

Backup Roll. The back up roll is a roll that supports the work roll and is the largest and heaviest roll used in rolling mills. The roll can support intermediate roll for the purpose of avoiding deflection of the work roll and affect on the yield and quality of the plate and strip rolling mill. The quality characteristics of the backup roll are high surface hardness, good hardness uniformity and the deep .
This oil plateout is very important in obtaining proper lubriion and hence proper strip surfacequality. If the rolls run too cold, insufficient oil plateout may occur and strip surface suffers. Like for hot rolling, oil can be applied to the roll gap soby called direct appliionure oil is sprayed into the . P roll gap just before the bite. For cold rolling of stainless steel based ...
· COLD ROLLING Cold rolling occurs with the metal below its recrystallization temperature (usually at room temperature). It also improves the surface finish and holds tighter to smaller size of the workpieces and their greater strength than hotrolled stock, fourhigh or cluster mills are used. Commonly coldrolled products include sheets, strips and rods; products being smaller ...
2: Three high rolling mill: It consists of a roll stand with three parallel rolls one above the other. Adjacent rolls rotates in opposite direction. So that the material may be passed between the top and the middle roll in one direction and the bottom and middle rolls in opposite one. In three high rolling mills the work piece is rolled on both ...
