Scrap steel preheating system of electric arc furnace

The utility model relates to a scrap steel preheating system of an electric arc furnace, which makes full use of physical and chemical surplus heat of high-temperature smoke gas of the electric arc furnace to realize preheating of steelmaking raw materials of the electric arc furnace. Moreover, the scrap steel preheating system utilizes a dust removing system to carry out filtration and temperature reduction on the high-temperature smoke gas of the electric arc furnace, so as to achieve the purposes of energy saving, consumption reduction, emission reduction and environmental protection of theelectric arc furnace. Meanwhile, the scrap steel preheating system increases the steelmaking productivity of the electric arc furnace, and realizes preheating of the high-temperature smoke gas and investment reforming of scrap steel in present old workshops. The scrap steel preheating system comprises scrap steel preheating material basket mechanisms and a material basket rotary swinging mechanism. The material basket ro
