热处理用电阻炉的耗电量很大,近年来,各单位在节约热处理电炉用电上作了不少工作,并取得了明显的效果。其中最主要的是采用硅酸铝纤维毡改炉。但是,从目前情况来看,热处理用电阻炉的节电潜力还是很大的。例如:常用的井式气体渗碳炉的料筐和炉栅,是为了存放工件或气体循环均匀而设置的,但这些结构都是耐热钢铸件,壁厚大,重量重,甚至有些电炉的 Resistance furnace heat treatment power consumption is very large, in recent years, all units in the heat treatment furnace electric power made a lot of work, and achieved significant results. One of the most important is the use of aluminum silicate fiber felt furnace. However, from the current situation, heat treatment resistance furnace energy saving potential is still great. For example, the commonly used well type gas carburizing furnaces for baskets and grates are provided for storing workpieces or gas circulation uniformly, but these structures are heat-resistant steel castings with large wall thickness, heavy weight, and even some electric furnaces
