一、前言近年来,为了提高产品质量,节约能源消耗,在热处理领域人们从理论上,对传统热处理工艺进行了大量的分析研究,并提出了多种新工艺和新的加热时间的计算方法,在实践中已取得了良好的效果。对于GCr15钢制轴承套圈的淬火工艺,虽然过去进行过一些研究,但在实际生产中未获得广泛应用。实际生产中,轴承套圈淬火加热的保温时间缩短多少为妥,缩短保温时间后对热处理淬回火质量有无影响,即能否保证热检标准所规定的主要技术指标,这是关系到成品内在质量的优劣。本工作的目的 I. Introduction In recent years, in order to improve product quality and save energy consumption, people in the field of heat treatment in theory, the traditional heat treatment process conducted a lot of analysis and research and proposed a variety of new processes and new heating time calculation method, In practice, it has achieved good results. For GCr15 steel bearing ring quenching process, although some research in the past, but in actual production has not been widely used. The actual production, the bearing ring quenching heating shortening the number of how much is appropriate to shorten the holding time after quenching and tempering the quality of heat treatment has no effect, that is, to ensure that the thermal test standards set by the main technical indicators, which is related to the finished product Intrinsic quality of the pros and cons. The purpose of this work
