脱碳是钢在加热时表层碳量降低的现象。它产生在热加工中的加热过程中,产品脱碳除在特殊要求情况下做为一种手段使用外(如硅钢片),均被视为一种加热中的严重缺陷。本文着重谈谈产品脱碳的危害及在热处理过程中引起脱碳的原因和预防措施。一、脱碳的危害 1.降低钢的淬火硬度和耐磨性。因此对高硬度使用的工模具和轴承等是极为有害的,它降低产品的使用寿命。某厂在对Cr12MoV钢制滚丝轮做切
Decarburization is the phenomenon that the surface carbon content decreases when steel is heated. It produces during heating in the heating process, product decarburization except in special circumstances as a means of use (such as silicon steel), are considered as a serious heating defects. This article focuses on the dangers of product decarbonization and heat treatment in the cause of decarburization and preventive measures. First, the dangers of decarburization 1. Reduce the quenching hardness and wear resistance of steel. Therefore, the use of high hardness molds and bearings, etc. are extremely harmful, it reduces product life. A factory in the Cr12MoV steel rolling wheel to do cut
