horizontal vibration design of an electric arc furnace steelmaking conveying scrap preheating system, the system is composed of electric arc furnace, the preheating passage, preheating passage back include a feed bin, vibration conveyor, conveying channel, I-steel supporting structure. Electric arc furnace produce high-temperature flue gas in steel-making, enters the preheating passage, and scrap iron materials are countercurrent subjected to direct heat exchange, covered with a layer of insulating layer in the preheating channel outside, can prevent the flue gas heat loss, therefore, can greatly improve the scrap preheating feeding and feeding to the electric arc furnace, which can realize all the molten pool arc furnace operation. Therefore, has the advantages of simple structure, small occupation area, less investment,scrap preheating temperature is high, high thermal efficiency, convenient operation and the like, provides a novel preheating system for electric arc furnace steelmaking and transformation.
