为了开辟热处理的新能源,采用太阳能加热的盐浴淬火炉进行了几个钢种的淬火实验。本文就实验所用盐浴炉的结构及参数进行了详细说明,介绍了65Mn,40Cr和T12三个钢种的淬火加热工艺,其结果证明利用太阳能加热淬火是可能的。质量完全合乎要求。同时也提出了今后需要解决的问题。 In order to open up new sources of heat treatment, the use of solar heating salt bath quenching furnace conducted several quenching experiments. In this paper, the structure and parameters of the salt bath furnace used in the experiment are described in detail. The quenching process of the three steel grades 65Mn, 40Cr and T12 is introduced. The results show that it is possible to use the solar heating to quench the steel. The quality is completely satisfactory. At the same time, some problems that need to be solved in the future are also proposed.
