一、前言固体渗碳具有设备简单,适应性大,成本低等优点。因此,目前许多中小工厂还继续使用,即使在工业发达的国家也一直延用,有的还有所发展。如西德大多数工厂都同时采用固体渗碳和气体渗碳,并对固体渗碳做了许多研究工作,其中Degussa公司生产的渗碳剂质量最佳。目前国内生产的固体渗碳剂的渗速一般在0.10～0.15mm/h左右。因而在固体渗碳中就出现了生产周期长,效率低,能源消耗大的缺点,限制了固 I. Introduction Solid carburizing has the advantages of simple equipment, large adaptability and low cost. Therefore, many small and medium-sized factories continue to be used at present, even in developed countries, they have been extended and some have been developed. For example, most factories in West Germany use both solid carburizing and gas carburizing. Much research has been done on solid carburizing. Among them, Degussa produces the best quality carburizing agent. The current domestic production of carburizing agent infiltration rate is generally 0.10 ~ 0.15mm / h or so. Thus in the solid carburizing appeared on the production cycle is long, low efficiency, high energy consumption shortcomings, limiting the solid
