摘　　要：研究了一种高耐磨矿用链轮链齿的热处理工艺。通过对链轮链齿链窝部位进行渗碳淬火处理,使链轮链齿链窝部位表层2.5 mm渗层内硬度达到55~60 HRC,表层2.5~35 mm渗层硬度达到50~55 HRC。与传统链轮相比,高耐磨链轮链齿链窝部位2.5 mm渗层内组织中碳化物较多,有效保证了链窝的耐磨性能,提高了链轮的使用寿命。Studied a heat treatment process for high wear-resistant mining sprocket tooth.By performing carburizing and quenching treatment on the sprocket tooth pit,the hardness of the 2.5 mm carburized layer on the surface of the sprocket tooth pit reaches 55-60 HRC,and the hardness within 2.5-35 mm of the surface reaches 50-55 HRC.Compared with traditional sprockets,the high wearresistant sprocket tooth pit has more carbides in the 2.5 mm carburized layer microstructure,which effectively ensures the wear resistance of the sprocket pit and improves the service life of the sprocket.
