FEM Analysis and Pass System Optimization of 16^#Ⅰ Beam during Rolling

In this paper FEM software were used to simulate rolling process of conjugated pass system of some enterprise,bend and twist of rolled piece during rolling had been identified. The reasons which caused these problems had been found out by quantification and transformation analysis,and optimization of pass parameters had been conducted based on common central roll rolling process. Using FEM to verify optimized pass,and the result indicated that the problems had mainly solved and optimized pass can be used in actual production.
