前言模具在机械制造工业中占有重要地位。由于少、无切削加工工艺的发展与推广,对冷冲、冷镦和冷挤压加工所需要的模具,不但需要数量多,而对质量的要求也越来越高,特别是要求尽可能长的使用寿命是模具行业中急待解决的问题。影响模具寿命的因素很多,而最重要的是热处理质量。从模具的失效原因分析中清楚看到,因模具热处理问题造成的失效占整个失效原因的50％,其中热处理的氧化脱 Preface Mold in the machinery manufacturing industry occupies an important position. Due to the small, non-cutting processing technology development and promotion of the cold red, cold heading and cold extrusion processing mold required, not only the number required, and the quality requirements are getting higher and higher, especially as long as possible The service life of the mold industry is an urgent problem. Many factors affect the life of the mold, and the most important thing is the quality of heat treatment. From the mold failure analysis clearly shows that due to mold heat treatment failure caused by 50% of the total failure causes, including heat treatment of the oxidation off
