RJJ—60井式气体渗碳炉是工业上对工件进行表面硬化的热处理设备。它是五十年代仿苏式的结构,炉膛密封性不好,漏气,散热比较严重,耗电多,加工周期长,使加工的成本提高,是工业炉窑的“电老虎”。为了降伏这只“电老虎”,我们在铜井耐火材料厂的大力协作下,采用全硅酸铝砖对北京叉车一分厂的一台炉进行了改装硅酸铝保温材料具有重量轻、耐高温、导热系数低、隔热保温性好的优点在国外热处理电炉上已获得了广泛的应用,目前正向采用全厚硅酸铝纤维材料的方向发展。我们在改炉前后,共进行了六炉试验,在节电方面获得了较好的效果。
RJJ-60 Pit Gas Carburizing Furnace is a industrial heat treatment equipment for surface hardening of workpieces. It is the fifties Soviet imitation of the structure, the furnace seal is not good, leakage, cooling more serious, more power, long processing cycle, so that processing costs increase, is the industrial furnace “electric tiger.” In order to lower down the only “electric tiger”, we Tonghua refractory plant in the strong collaboration, the use of all aluminum silicate brick Beijing Forklift factory a furnace modified aluminum silicate insulation materials with light weight, resistance The advantages of high temperature, low thermal conductivity, good heat insulation and thermal insulation have been widely used in foreign heat treatment electric furnaces. At present, the development of full-thickness aluminum silicate fiber materials is going forward. Before and after the furnace reform, we conducted a total of six furnace tests and achieved good results in energy saving.
