双金属板热轧复合模拟及最小相对压下量的确定

在对复合板轧制过程中的粘合特性进行分析的基础上，采用了合理的轧制和界面假设条件，应用Marc有限元软件建立了包括上辊、双层金属在内的三维模型，对不锈钢／碳钢复合板的热轧复合过程成功的进行模拟，获得了不同相对压下量条件下，轧制变形区内应力应变的分布、界面上应力分布以及接触表面上轧制力的三维分布。在此基础上分析得出了最重要的轧制工艺参数，即不锈钢／碳钢复合板热轧复合所需的最小相对压下量，这与在某钢厂所作的生产性试验是一致的。

Simulation on hot rolling compounding of two metal plates and determination of minimum relative reduction

Based on bonding character analysis of the clad plate in rolling process with some hypotheses, three-dimensional model included the upper roll and double-ply metal is set up. Hot rolling compounding process of stainless/carbon steel plate have been simulated. The stress and strains distribution in the deforming region, stresses distribution at the interface and the specific rolling pressure 3-D distribution on the contact surface have been obtained in various relative reductions. Most important technology par- ameter, namely minimum relative reduction for perfect compounding have been found. This result is in good agreement with the experimental results in a hot rolling sheet plant.
