在轴承制造中,热处理是很重要的。各国对热处理工艺与装备在进一步研究。 当设计轴承用热处理炉时,时常要碰到的问题就是要热处理的零件形状或尺寸的范围过于广泛。 过去的一般倾向是按生产量方面的要求设置小型炉。但近年来为了扩大生产量和减少热处理成本,出现了把装料限制在一定范围内的近似专用炉式的大型热处理炉。同时为了进一步提高热处理质量,缩短热处理后的工序等原因盛行保护气体热处理炉。
In the manufacture of bearings, heat treatment is very important. Countries on the heat treatment process and equipment for further research. When designing bearing heat treatment furnaces, the problem often encountered is that the shape or size of the part to be heat treated is too wide. The general trend in the past was to set up small furnaces as required by production volume. However, in recent years, in order to expand the production volume and reduce the cost of heat treatment, a large-scale heat treatment furnace having an approximately special furnace type which limits the charging within a certain range has appeared. At the same time in order to further improve the quality of heat treatment, shorten the heat treatment process and other reasons prevailing protective gas heat treatment furnace.
