摘要
本文根据生产实践，分析了影响柴油机球墨铸铁曲轴质量的热加工工艺因素，同时提出了提高曲轴使用寿命的方法：提高球墨铸铁曲轴的球化质量与牌号、消除铸造缺陷、采用合金化球墨铸铁和正火－氮化热处理工艺．
Based on productional practice, discussion has been made on the hot-working technologies affecting the quality of nodular cast iron crankshafts for diesel engine, and some methods for improving crankshafts' operating lives have been suggested, which include enhancing the nodulized quality and grade of nodular cast iron crankshafts, eliminating casting defects, applying alloyed nodular cast iron and adopting normalizing-nitriding heat treatment technology.
