花纹板热轧过程中板坯复杂的变形过程导致难以确定合理的花纹板热轧工艺及控制参数,运用ABAQUS有限元软件,对花纹板轧制三维热力耦合过程进行数值模拟,得到花纹板热轧过程中的应力、应变和温度场分布规律.花纹板轧制前后存在明显的应力和温度分布不均匀,这会直接导致应变分布不均匀.最大的等效应变产生在无豆形基板的上层,导致该部分的晶粒尺寸最小.通过试验验证了有限元模型的可靠性,为实际生产提供了可靠的理论依据.
Numerical Simulation and Experimental Study on Non-Uniform Deformation of Hot-Rolled Pattern Plate
The bean-shaped complex deformation process of pattern plate during hot rolling makes it difficult to determine reasonable hot rolling process and control parameters.In this paper,the three-dimensional thermo-mechanical coupling process of pattern plate rolling is numerically simulated by using ABAQUS finite element software,and the distribution rules of stress,strain and temperature field in the process of pattern plate hot rolling are obtained.There is an obvious non-uniform distribution of stress and temperature before and after rolling,which will directly lead to the uneven distribution of strain.The maximum equivalent strain occurs on the upper layer of the non-bean-shaped substrate,resulting in the smallest grain size.The reliability of the finite element model is verified by experiments,which provides a reliable theoretical basis for practical production.
