【摘要】：通过有限(FEM)元速度场研究了冷轧铜铝双层板的复合过程,将该过程中金属的变形特征进行了分析,同时,将有限元计算结果与某工厂数据相结合,分析了轧制速度、压下率、异径同步、异径异步对铜铝双层板复合的影响。结果表明,速度场模型能够更有效地说明铜铝板的复合过程;轧制速度越大,变形区出口处复合面金属流动的同步性越差,复合强度越低;异径同步轧制铜铝复合板时,辊径比取1.4~1.6,变形区出口处复合面金属流动的同步性越好,复合强度较高;异径异步轧制铜铝复合板时,轧制速比取1.2,变形区出口处复合面金属流动的同步性越好,复合强度较高。
[Abstract]:The composite process of cold-rolled copper-aluminum bilayer plate was studied by the finite FEM-element velocity field. The deformation characteristics of the metal in the process were analyzed. At the same time, the finite element calculation results were combined with the data of a factory. The effects of rolling speed, reduction rate, different diameter synchronism and diameters asynchronously on the composite of copper and aluminum bilayers are analyzed. The results show that the velocity field model can more effectively explain the process of copper aluminum sheet compounding. The higher the rolling speed, the worse the synchronism of the metal flow at the exit of the deformation zone, and the lower the composite strength. In the process of synchronously rolling copper and aluminum composite plates with different diameters, the ratio of roll diameter to diameter is 1.4? 1. 6. The better the synchronicity of metal flow at the outlet of deformation zone, the higher the composite strength. When the rolling speed ratio is 1.2, the synchronism of metal flow at the outlet of deformation zone is better and the composite strength is higher.
