摘　　要：针对复合厚板轧制过程头部翘曲问题,采用ABAQUS软件进行有限元建模分析,对网格无关性进行了验证,得出了合理的单元尺寸;研究了板坯来料厚度、轧制压下率、板坯上下表面温差及轧辊速比对复合厚板头部翘曲的影响规律。In view of head warping problem in hot rolling of clad plate, the commercial software ABAQUS was used to FEM simu- lation. Firstly, the models accuracy was proved, and the size of element was properly setting. The influence of initial sheet thick- ness, reduction, the temperature difference between up and below surface, velocity ratio of up and below rolls on head warping were analyzed, the solutions for the problems of head warping were provided.
