摘要：

采用有限元法，进行了电辅助不锈钢/碳钢轧制复合过程的模拟，对电流场、温度场和金属流动规律进行了分析。研究了初始厚度比、压下率、电流密度、轧制速度作为变量对不锈钢/碳钢复合板的复合厚度比的影响。结果表明：各因素单独作用时，减小初始厚度比、减小压下率、增大电流密度、增大轧制速度均能降低复合厚度比；而多因素复合作用时，增大压下率反而能增大不锈钢板上的电流密度，从而提高其温度，使得复合厚度比降低；初始厚度比对复合厚度比的作用效果最大，其次为电流密度，最后是压下率及轧制速度。

The electrically assisted rolling process of stainless steel/carbon steel was simulated by the finite element method, and the current field, temperature field and metal flow law were analyzed. Then, the influences of initial thickness ratio, reduction ratio, current density and rolling speed as single variables on the composite thickness ratio of stainless steel/carbon steel composite plate were studied. The results show that when each factor acts alone, reducing the initial thickness ratio, reducing the reduction ratio, increasing the current density and increasing the rolling speed can all reduce the composite thickness ratio. But when all factors act, reducing the reduction ratio can increase the current density on stainless steel plate, thus increasing its temperature and reducing the composite thickness ratio. The initial thickness ratio has the greatest effect on the composite thickness ratio, followed by the current density, and finally the reduction ratio and the rolling speed.
