Scrap steel preheating system for electric arc furnace

The invention relates to a scrap steel preheating system for an electric arc furnace, which realizes the preheating for steelmaking raw materials for the electric arc furnace by fully utilizing the physical and chemical waste heat of high-temperature flue gas of the electric arc furnace and enables a dust removal system to filter and cool the high-temperature flue gas to achieve the purposes of energy saving, reduction of consumption, emission reduction and environment protection as well as improve the steelmaking production ratio of the electric arc furnace and to realize the investment and alteration of preheating scrap steel by high-temperature flue gas in a current old factory workshop. The scrap steel preheating system for an electric arc furnace comprises scrap steel preheating basket mechanisms and a basket rotation swing mechanism; the basket rotation swing mechanism is respectively connected with the scrap steel preheating basket mechanisms positioned at a scrap steel receiving position and a scrap s
