【摘要】 在从事各种模具钢的热处理加工生产过程中发现了一些模具钢变形、开裂的现象,通过研究、分析及总结,及时提出有效的方案解决了问题。实际工作中还总结了模具钢改性的几种方法:T10钢冷挤压凹模高温淬火使表面硬度达到66~67HRC;专利技术的盐浴渗矾使模具表面硬度达到3000HV以上,法国专利技术的盐浴硫碳氮共渗(SURSULF&ARCOR)用于生产,提高了产品质量及生产效率。更多还原

【Abstract】 Through study and analysis of the deformation and crack finding in the process of die steel heat treatment,the effective solution is proposed for this problem in time.Several die steel modification ways are summarized in practical work.For example,under the high temperature quenching the surface hardness of steel T10 may get 66～67HRC,patented vanadizing in salt bath used for the die and mould,the hardness of surface up to 3000HV.The product quality and production efficiency is improved by using French patented salt bath sulf-nitrocarburizing(SURSULF&ARCOR).更多还原
