本文阐述了破碎机锤头原来热处理工艺,并指出存在的问题。在此基础上,进行了一系列的板条马氏体强化工艺试验,从中摸索出35SiMn钢锤头的最佳板条马氏体强化工艺。就此论述了这一工艺方法的优点,并分析了板条马氏体和针状马氏体性能不同的内在原因,指出了获得板条马氏体组织的热处理工艺途径,为推广这一新的工艺方法提出了依据。 This article elaborates the original hammer heat treatment process, and points out the existing problems. On this basis, a series of lath martensite strengthening process tests were conducted, from which the optimum lath martensite strengthening process of 35SiMn steel hammer was worked out. This article discusses the advantages of this process, and analyzes the inherent causes of lath martensitic and acicular martensite properties. It also points out the ways of heat treatment for obtaining lath martensite. In order to promote this new Process method is based on.
