早在五十年代末,第一汽车制造厂组织了工艺试验队伍,经过了近十年的努力,在吸热式保护气氛制备、气氛露点控制、用新型的气氛取代原设计煤油裂解气、各种能源加热元件的定型等,经大量试验、设计并制造出无罐连续式气体渗碳炉,碳氮共渗震底炉,应用吸热式保护气氛保护加热零件,一些承受疲劳及磨损的调质和渗碳或碳氮共渗件,改为感应加热淬火,如后桥半轴、球销、变速叉、转向节等,取得了很大的成果。六十年代末,开始建设第二汽车制造厂。这是个新建企业,应用了一汽热处理工艺和装备的研究成果,同时考虑到二汽的特点,在工艺选择上又有所发展。例如,二汽全部采用电能加热,无罐式连续渗碳自动线,震底
As early as the late fifties, FAW FAW organized a process test team. After nearly a decade of efforts, it was prepared in a heat-absorbing protective atmosphere and the dew point of the atmosphere was controlled. The original design kerosene pyrolysis gas was replaced by a new atmosphere After a large number of tests, a series of gas-free continuous carburizing furnaces and carbonitriospondose heart-shaking furnaces were designed and manufactured. Heat-absorbing protective atmospheres were used to protect the heated parts. Some of the fatigue and wear-resistant Quality and carburizing or carbonitriding pieces, replaced by induction heating quenching, such as the axle after axle, ball pin, speed fork, steering knuckle, and achieved great results. The end of the sixties, began building second automobile factory. This is a new business, the application of FAW heat treatment technology and equipment research results, taking into account the characteristics of steam, in the process of choice and development. For example, the two steam all electric heating, continuous carburizing tank without automatic line, the end of the earthquake
