rolling mill configurations

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.
