众所周知,高速钢具有许多优良的和特殊的性能(红热硬性和耐磨性等),因此,在生产中有大量刀具都是由高速钢制成。但要使高速钢刀具获得最佳性能,必须经过复杂和费时间的热处理过程(预热及最后高温加热淬火、多次高温回火等)。如果能在保证质量的前提下,如何缩短高速钢的热处理过程,将具有很大的经济价值。本文仅就高速钢的快速回火问题进行研究。 As we all know, high-speed steel has many excellent and special properties (red hot hardness and wear resistance, etc.), therefore, in the production of a large number of tools are made of high-speed steel. But to get the best performance HSS tool must go through complex and time-consuming heat treatment process (preheating and the last high-temperature quenching, high temperature tempering, etc.). If we can guarantee the quality of the premise, how to shorten the high-speed steel heat treatment process, will have great economic value. This article only on the rapid tempering of high-speed steel research.
