摘　　要：对ＣｒＷＭｎ钢制硅钢片冷冲凹模进行了循环加热低温淬火的热处理，使凹模使用寿命获得显著提高，降低了产品成本，提高了经济效益。Through the quenching treatment of the silicon- steel-piece die of CrWMn steel carried out by cycling heating low temperature quenching, the service life of the die is re- markably prolonged and the production cost is reduced, so that the economic beneficial result is greatly increased.

关 键 词：冲模 硅钢片 循环加热 低温淬火
