摘要：

The purpose of this article is to solve the uneven deformation problem of electrical steel strip caused by high-temperature phase transition during hot rolling process. The hot rolling process of electrical steel strip is built by ABAQUS software, importing the constitutive model of electrical steel. The effect of temperature drop in the edge of electrical steel strip on the profile and flatness of strip is studied. Simulation results show that the strip edge temperature drop has great effect on hot rolling process of electrical steel strip. When electrical steel strip is in single-phase state, the strip edge temperature drop can reduce the strip crown, but also lead to larger rolling pressure and local high point height in the strip edge. When electrical steel strip is in two-phase state, the local high point height in the strip edge does not exist, but the strip edge temperature drop can lead to larger strip crown.
