高锰钢部件的使用寿命与其运转条件有关,特别是某些破碎与研磨设备中的锤头、衬板等部件,由于运转中的冲击负荷较小,不能够充分发挥高锰钢的加工硬化特性,故其使用寿命较低。对此我们采用生铁焊条堆焊高锰钢锤头增加其工作面硬度的方法,提高了工作面的耐磨性,延长了锤头使用寿命。 The service life of high manganese steel parts and its operating conditions, especially in some crushing and grinding equipment, hammer, lining and other components, due to the operation of the impact load is small, can not give full play to high manganese steel work hardening properties , So its service life is low. In this regard, we use pig iron electrode surfacing high manganese steel hammer to increase the hardness of the work surface to improve the wear resistance of the work surface, extending the life of the hammer.
