矿用磨机大型铸钢齿轮制造技术

Manufacturing Technology of Large Cast Steel Gears for Mining Mill

通过合理选材,对铸造、熔炼、热处理等工艺长期优化,形成了中信重工矿用磨机大型铸钢齿轮的核心制造技术。实践证明,利用该技术生产的大型铸钢齿轮其内部质量和力学性能能够达到要求,满足磨机在不同工况下的使用。

Through reasonable material selection and long-term optimization for casting method,smelting and heat treatment processes,the core manufacturing technology of large cast steel gear for mining mill of CITIC Heavy Industry is developed.The practice proved that using this technology producing the large cast steel gears can ensure that the internal quality and mechanical properties of gears meet the use of the mill under different working conditions.
