Roll Pass design for steelThe cross sectional area is reduced in each pass and the form and size of the stock gradually approach the desired profile. Here the thickness of the metal being rolled is reduced in each pass by decreasing the distance between the rolls. The subsequent passes in rolling section steel are called roughing passes.

Steel Rolling Mill Machine: Hot Rolling VS Cold Rolling

After hot rolling, non-metallic inclusions (mainly sulfides and oxides, as well as silicates) in steel are pressed into thin sheets, resulting in stratification (interlayer). Layering deteriorates the tensile properties of steel along the thickness direction, and interlaminar tearing may occur when the weld shrinks. Local strain induced by weld shrinkage often reaches several times of yield ...
