摘　　要：针对现有的不锈耐酸钢球冷敦过程中,球坯在顶端损伤明显,冷镦工具磨损严重。利用有限元分析软件来模拟钢球冷镦过程,对不锈耐酸钢棒材进行加温处理,降低其变形抗力。结果表明:新工艺冷镦最大应力相对旧工艺降低了9.9%,工具磨损也较均匀。The top of ball blank is damaged seriously and tool is badly worn in the process of cold heading stainless acid-re- sistant steel ball. Finite element analysis software is used to simulate this process, and stainless acid-resistant steel stick is heated up so as to reduce the deformation resistance. The results show that the maximum stress of cold heating in the new process reduces by 9.9% and tool is worn uniformly.
