Computer Simulation of Piercing in a Four-High Screw Rolling Mill

Resumo

A piercing process for a new four-high screw rolling mill without guides designed by comparing existing piercing processes in screw rolling mills is proposed. To evaluate the feasibility of this process, piercing in two-, three-, and four-high screw-rolling mills was simulated using QForm FEM software. Simulation results demonstrate advantages of the new piercing process according to several criteria, including energy consumption.
