对井式炉滴注有机液气体渗碳,是目前国内普遍采用的气体渗碳工艺,它具有设备简单,操作方便,渗碳层质量稳定,成本低等特点。然而,它的生产周期长,不能达到碳势自动控制,是它的不足,国内外对此也进行了大量的研究和实验,如采用多段式渗 Injecting organic liquid gas carburizing to the pit furnace is the commonly used gas carburizing process in our country. It has the characteristics of simple equipment, convenient operation, stable carburized layer quality and low cost. However, its long production cycle, can not achieve the carbon potential of automatic control, is its lack of domestic and foreign also conducted a lot of research and experiments, such as the use of multi-stage seepage
