Rolling Process: Working, Application, Defects, Type of ...
Four High Rolling Mills: In this type of mill, there are four parallel rolls one by another. In this operation, the rotation of the first and the fourth rolls take place in the opposite direction of the second and the third rolls. The second and third rolls are smaller to provide rigidity in necessity. So those are known as back up rolls.

Study on minimum rollable thickness in asymmetrical rolling
Thus, the deformation zone configuration-rolling parameter relationship diagram is obtained. Based on the analysis of this diagram, when the rolling parameters keep the deformation zone configuration as C + B or AC, the rolling mill has the strongest thinning ability. The minimum rollable thickness can be obtained as the following: 1.
