冷处理在工具制造领域内的应用,引起了国内外有关方面的重视,最近几年发表文章亦较多。但有关冷处理的工艺规范这方面公开发表的资料就较少。从了解到的资料看,还经常有矛盾。譬如,冷处理时要不要预冷,冷处理工序应该放在淬火后进行好,还是放在回火后进行;在低温保持一段时间后是自然升温好,还是快速升温好等等,看法都不一致。一、要不要预冷约翰·太勒在文章中提到英国BOC The application of cold processing in the field of tool manufacturing has aroused the attention of domestic and foreign parties concerned and more articles have been published in recent years. However, there is less information published publicly in this area regarding cold process specifications. From the understanding of the information, there are often contradictions. For example, cold treatment should not be pre-cooling, cold treatment process should be placed after quenching, or on the tempering; maintained at low temperatures for a long time after the natural warming is good, or rapid warming, etc., the views are inconsistent. First, to pre-cold John Taylor in the article mentioned the British BOC
