论新型电阻炉的技术特点及超大型炉设计关键点

Technology Specification of New Type Electrical Resistance Furnace and Keypoint in Design of Super Large-sized Furnace

全纤维移动罩式、对开罩式、钟罩式新型电阻炉,以全新的构思、新型材料和先进的控制手段,为改变我国目前电阻炉落后状态开辟了新途径。新型电阻炉在加热精度、节能效果、生产效率和操作可靠性等方面都有很大提高。新技术为电阻炉超大型化提供了可能性,在超大型移动电阻炉设计中解决了炉体的稳定性、炉体的供电结构、炉气循环搅拌系统和炉体钢架的共振等问题,为电阻炉超大型化奠定了基础。2002年建造的“16m×6m×6m大型对开罩式电阻炉”是目前国内最大的移动罩式电阻炉。

The development of new type electrical resistance furnace of full refractory fiber such as movable cover furnace,split-type cover furnace and bell-type furnace have established new path to change the behindhand state of electrical resistance furnace in our country with new concept,new type material and advanced control method.The new type electrical resistance furnace has much improvement in heating accuracy,energy saving effect,production efficiency and operation reliability.The new technology makes it possible to produce super large-sized electrical resistance furnace and to solve problem of stability of furnace body,power supply construction of furnace body,gas circulating and mixing system in furnace,sympathetic of furnace body steel frame.The large sized split-type cover electrical resistance furnace of 16m×6m×6m built this year is the largest movable cover furnace in our country at the present time.
