Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening.The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and …

The experiments of sheet and strip rolling are carried out on a 4–high reversible cold rolling mill in Yanshan University. The work roll's diameter is 100mm. The backup roll's diameter is 200mm, and the roll body's length is 300mm. The experimental method is seen in the Reference [5]. The rolled pieces are singles and coiled strip of aluminium.

Having a large diameter back up roll allows the mill to run at high rates of speed compared to an old 20-high mill. To do high reductions on high carbon or stainless steel alloys up to 50% in a single pass, considerable tension can be required. This also reduces the amount of energy that the rolling mill itself has to perform.
