摘　　要：针对铁路轴承锻件冷却缓慢导致粗大网状碳化物形成并且在淬火或使用中产生裂纹的现象,设计制造了贯通式半自动锻件组织细化机,提高了轴承使用寿命。In view of the phenomenon that railway bearing forgings cooled slowly to result in emerging of thick netted carbide and appear of crack in the course of quenching or use,the link-style semi-automatic texture fining machine was designed and manufactured.The service life of bearing was eventually raised.
