5 CrMnMo作为一种常用的模具材料,由于其来源充足,价格便宜,故从当今模具钢中所占的比例来看,仍无衰减之势.如何提高5 CrMnMo钢热锻模的使用寿命,仍是同行们所关注的问题之一. 我们厂将5 CrMnMo钢热锻模的常规热处理改为复合热处理,同时还认真抓了使用中的有关问题,使煤矿机械金属支柱的重要组件楔块、水平楔锻模寿命有了较大的提高.楔块锻模寿命由原来的763件/副提高到1470件/副,最高可达2000件/副以上;水平楔锻模的平均使
5 CrMnMo as a common mold material, due to its abundant sources, the price is cheap, so from the proportion of today’s mold steel, there is no decay trend.How to improve the service life of 5 CrMnMo steel hot forging dies, still Is one of the concerns of colleagues.We plant 5 CrMnMo steel hot forging die conventional heat treatment to composite heat treatment, but also carefully grasped the use of the relevant issues, so that the important components of mining machinery metal pillars wedge, level Wedge forging die life has been greatly improved. Wedge forging die life from the original 763 / vice increased to 1470 / pair, up to 2000 / deputy or more; horizontal wedge die average
