本刊1963年6月号“高速鋼的热处理新工艺”一文(以下称原文)中对高速鋼热处理工艺提出一些建議,其主要內容是以低温淬火后高温回火代替退火工序,以及高温快速回火代替三次回火处理。前者具有一定的价值,可在生产实踐中作进一步檢驗;后者早巳被提出,但由于一系列原因(諸如透热、回火均勻程度,工艺操作以及可靠的参数尚未拟定、一系列性能数据尚未建立等等),并未得到实际应用。可惜的是,原文作者在这方面也沒有提供新的資料。
The publication June 1963 “high-speed steel heat treatment of new technology” article (hereinafter referred to as the original) on the high-speed steel heat treatment process put forward some proposals, the main contents of the high temperature tempering after the low temperature quenching instead of annealing process, and high temperature rapid back Fire instead of tempering three times. The former has some value and can be further tested in production practice; the latter has already been proposed, but due to a number of reasons (such as diathermy, uniformity of tempering, process operation and reliable parameters have not been developed, a series of performance Data has not been established, etc.), has not been practical application. Unfortunately, the original author did not provide any new information in this regard.
