摘要
高温回火可消除模具淬火时产生的残余应力,避免模具在后续的电加工中产生变形;而采用超低温工艺处理后,模具的耐磨性可提高2～3倍,延长了模具的使用寿命。
The high temperature tempering can eliminate the residual stress caused by quenching, this can avoids the deformation in the following electric machining; after ultralow-temperature disposal process, the wear resistance of die increases 2 to 3 times, so its using time is consumedly prolonged.
