完善的铸造工艺技术生产出内部无缺陷高质量的球铁齿轮铸件，经铁素体化处理后，改善其机械 加工性能，然后应用先进的等温淬火工艺和设备进行贝氏体化热处理。得到硬度较高的下贝氏体＋马氏体组 织，再经过表面喷丸强化使齿轮弯曲疲劳性能大幅度提高。从而获得可代替传统渗碳钢的高强度、高耐磨性 的硬齿面齿轮。
Perfect casting technology to produce the internal defect-free high quality ductile iron gear castings, after ferritic treatment, to improve its machinability, and then use the advanced isothermal quenching process and equipment for bainitic heat treatment. Lower bainite + martensite with higher hardness is obtained, and then the performance of gear bending fatigue is greatly improved through surface peening. This results in a hardened face gear that can replace the traditional carburized steel with high strength and wear resistance.
