高速钢扁锭锻造成方坯时 ,端面产生较大横向裂纹 ,并向内部扩展 ,为减小端面裂纹大小 ,降低裂口向内延伸长度 ,在微机上采用刚粘塑性有限元分析法对其锻造过程进行模拟研究 ,分析出了形成此裂纹的主要原因 ,据此提出了合理工艺参数和改进的锻造工艺措施。 When the high-speed steel ingot is forged into a billet, the transverse crack occurs in the end face and expands inwardly. In order to reduce the size of the end face crack and reduce the inward extending length of the crack, the rigid visco-plastic finite element analysis method is used to forge Process simulation study, the main reason for the formation of the crack is analyzed, and reasonable process parameters and improved forging process measures are proposed accordingly.
