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.

I summarizes the typical thicknesses and rolling speeds for each mill type. Not surprisingly, as the material gets thinner, the speeds increase dramatically. Hot Roughing Mill Hot Finish Mill Cold Rolling Mill Maximum Thickness > 400 mm 2050 mm 320 mm Minimum Thickness 2050 mm 320 mm mm Rolling speeds (meters per min) ~ 100 ~ 1000 ~ 2000

Reduction of the foil thickness is controlled by adjusting roll speed viscosity, and lubricant temperature, while the roll gap determines the thickness and length of the final foil product. Pure or lowalloy aluminum can be reduced from sheets about an inch (25mm) thick down to a foil of () thick through coldrolling processes.

The theoretical framework is developed for a new theory of cold rolling thin metallic foil. Unlike previous theories, the work rolls are allowed to deform to a noncircular profile and finite regions of noslip between strip and work rolls are allowed to occur in the roll bite. The theory predicts that plastic reduction occurs near entry and ...

Cold Rolling. In the cold rolling process, a hotrolled coil is made thinner by passing it between two rolls at room temperature. Not only is the thickness of the material made uniform, but the internal structure is made homogeneous at a microscopic level, and the surface of the roll is transferred to the material to provide a polished finish.
