5 CrMnMo钢作为一种常用的模具材料,虽然其综合性能不及国外的一些新材料,但其来源充足,价格便宜,而且在当今模具钢中仍占有重要地位。提高5 CrMnMo钢热锻模的使用寿命,是节省模具材料、提高经济效益的重要途径。我厂将5 CrMnMo钢热锻模的常规热处理改为复合热处理,严格控制锻模预热、工作节奏、冷却润滑、材料的始锻温度等使用中的几个问题,使金属支柱锻件楔块、水平
As a commonly used mold material, 5 CrMnMo steel, although its comprehensive performance is inferior to some foreign new materials, is abundant in source and cheap in price, and still occupies an important position in today’s mold steel. Improve the service life of 5 CrMnMo steel hot forging die is to save mold materials, an important way to improve economic efficiency. Our factory will 5 CrMnMo steel hot forging die conventional heat treatment to composite heat treatment, strictly control forging die preheating, working tempo, cooling lubrication, the material forging temperature and other use of several problems in the metal forgings wedge, Level
