Effects of Continuous Rolling Speed Change Rates on Geometric Dimension between Two Racks when Rolling Rail by Universal Pass

Abstract:

This paper used the finite element software to simulate the process of the heavy rail rolling deformation between the UR and ER racks. It studied on the stress distribution law of the universal mill pass, the relationship between the universal mill unbalanced rates of velocity and tension changes of the rack, effect of the universal mill unbalanced rates of velocity on the change of the rolling geometric dimensions caused by the unbalanced rates of velocity. The research can guide the adjustment of the dimensional accuracy of the rail’s universal rolling.
