本文着重介绍了 V 型滚道中频淬火感应器设计参数的确定,以及加热规范与电规范的制定。作者还就影响滚道使用寿命的热处理质量因素:淬硬层深度及组织的均匀性,表面硬度等进行了论述,目前该厂该零件淬硬层已达到3.5毫米,接火带只有12毫米宽,超过了一机部基础件攻关要求(淬硬层3毫米,接火带宽20毫米) This article focuses on the V-type raceway IF quenching inductor design parameters to determine, as well as heating norms and electrical specifications. The author also discusses the quality factors of the heat treatment affecting the service life of the raceway: the depth of the hardened layer and the uniformity of the structure, the surface hardness and so on. At present, the hardened layer of the part of the plant has reached 3.5 mm and the fire belt is only 12 mm wide , More than a machine part of the basic offensive requirements (hardened layer 3 mm, then fire bandwidth 20 mm)
