本文提出了一种新的有限元方法来模拟轧制过程中夹杂物的变形和裂纹的产生，即在夹杂物和板带基体之间建立一个过渡层，并考虑材料的破坏。用该程序模拟了304不锈钢冷轧过程中夹杂物的行为，计算结果表明，夹杂物与基体的结合强度对轧制过程中裂纹的产生有明显的影响，结合强度越低，裂纹产生的可能性越大。通过模拟夹杂物与基体之间存在过渡层的轧制过程中夹杂物的行为，分析了轧制条件和夹杂物与基体之间的结合强度对带钢质量的影响。
A new method has been proposed for simulating the inclusion deformation and the crack generation during rolling by finite element method, in which a transition layer between the inclusion and the strip matrix is established and the material failure considered. The inclusion behavior in type 304 stainless steel strip during cold rolling has been simulated with it. The calculated results show that the bond strength between the inclusion and the strip matrix clearly affects the crack generation during rolling, and that the lower the bond strength is, the more possible the cracks appear. Simulation of the behavior of inclusion during rolling with the transition layer between the inclusion and the strip matrix gives a way to analyze the effects of the rolling conditions and the bond strength between the inclusion and the strip matrix on the strip quality.
