以高压成型法制备合金粉末预置块,在合金化部位的铸型上采用局部保温和排气措施,以40Cr钢和ADI球铁为母材制造冲压模具,经现场应用试验表明,其使用寿命为常用的Cr12MoV、Cr-WMn模具的4倍以上。
Preparation of alloy powder pre-block by high-pressure forming method, partial insulation and exhausting measures were adopted on the castings of the alloyed parts, 40Cr steel and ADI ductile iron were used as the base material to make the stamping die. The field application tests showed that the service life For commonly used Cr12MoV, Cr-WMn mold more than 4 times.
