Abstract：

The first pass rolling process of stainless steel 316L and carbon steel Q235 composite plate at 1200 ℃ was simulated by software ABAQUS. The ratio between the maximum vertical compressive stress and the plane deformation resistance of hard metal was used to evaluate the bonding properties of the composite plate, and the rates of the interfacial bond with different pressures were obtained. Compared with the experimental data, the simulated results of the interfacial bond are a little higher under the same compression rate. In order to eliminate the difference between the simulated results and the experimental results to make the simulated results closer to the experimental results, the ratio of the discriminant was amended to 1.03975 based on both the simulated data and experimental data. The interface bonding ratio was closer to experimental results after amendment. The validity of the finite element model and the feasibility of the evaluation in the simulation process were verified by the experimental results. In addition, the interface binding rate increased exponentially with the increase of the first reduction rate.
