摘　　要：由于传统热作模具钢的高温强韧性不能满足钢挤压工模具的要求以及综合成本较高等原因,提出了适合用于钢挤压工模具的热作模具钢材质1.2367,并将其与传统热作模具钢进行对比;对各种钢挤压工模具材质选择、适宜的热处理硬度及使用规范进行了较为详细的叙述;对频繁水冷容易造成模具钢热疲劳的问题,提出了利用多件工模具循环使用并采取自然冷却的方法代替水冷的观点。For the high temperature strength and toughness of the traditional hot working die steel materials can not meet the requirement of the steel extrusion toolings, and their comprehensive costs are high, so the hot working die steel material 1. 2367 suiting for steel extrusion toolings was proposed. And the differences between them and the tra- ditional hot working die steel materials were compared. The material selection, suitable hardness after heat treatment and use specification of each steel extrusion toolings were described in detail. The frequently water cooling usually re- sulted in the die steel thermal fatigue, so the viewpoint of water cooling replaced by several toolings cycle use and natu- ral cooling was proposed.
