摘　　要：株洲齿轮有限公司已成功地以净化后的天然气代替丙烷气用于渗碳。这项工程所取得的成果表明,更换渗碳原料气的设备改造和调试工作量小,更换原料气后产能和产品质量提高,生产成本显著下降。经过净化的城市天然气在热处理行业具有广阔的应用前景。Propane gas has been successfully replaced by purified natural gas for carburizing in Zhuzhou Gear Co. , Ltd. The results obtained from this indicate that equipment reformation and process debuging in the replacement of feed gas for carburizing are easy to perform, and that production capability and product quality after the replacement are enhanced and production cost is obviously decreased. The application of purified town natural gas to heat treatment will have a vast vistas.
