摘　　要：渗碳齿轮钢等温退火处理可以获得均匀、稳定的组织和硬度,对下游客户的冷锻加工性能有显著改善,提高了加工精度,并能减少齿轮最终渗碳淬火热处理变形。介绍了冷锻加工用渗碳齿轮钢的退火工艺、技术及产品性能。The isothermal annealing treatment of the carburized gear steel can achieve a uniform and stable structure and hardness, which can significantly improve the cold forging processing performance of the downstream customers. With im proved machining accuracy, it can also reduce the heat treatment distortion of the final carburizing and quenching of the gears. This paper introduces the development of annealing process, technology- and product performance of carburized gear steel for cold forging machining at Jiangy-in Xingcheng Special Steel Works CO. ,Ltd.
