摘    要：1973年能源危机发生以来,国外高度重视能源节约,在冶金、机械等工业领域里大力开展电炉节能研究。当前,电阻炉的主要节能技术是应用耐火纤维炉衬以及电阻直接加热;感应电炉节能的主要动向包括冷却水废热回收、炉料预热、联合供热以及选用高效率的变频设备;电弧炉节能的主要研究课题是炉料预热以及烟气废热的回收。

Abstract: Since the energy crisis began in 1973, the developed countries have beenpaying great attention to energy conservation, and a lot of investigations ofenergy conservation for electrical furnaces have been carried out in thefields of the metallurgical and machine-building industries. Nowadays, the principal technique of energy conservation for resistance-heated furnaces isto use ceramic fiber liner and direct resistance heating. The chief tendencyof energy conservation for induction furnaces includes the recovery of wasteheat from cooling water, the preheating of the charge, the combination heat-ing and the choice of high-efficient frequency converters. As to are furnacesthe primary investigation subjects consist of the preheating of the chargeand the recovery of waste heat from flue gas.
