Zusammenfassung:	A method for efficiently removing Cu in electric furnace steelmaking with regenerated steel raw materials comprises removing Cu in the electric furnace steelmaking and removing Cu deeply in RH/VOD steelmaking. The removing Cu in electric furnace steelmaking comprises removing Cu by spraying CaO-CaCl2-O2 in stages in the electric furnace steelmaking; the removing Cu deeply in the R/VOD steelmaking comprises removing Cu deeply by dynamically blowing CaCl2-O2 based on vacuum degree. Cu removing and Cu removing deeply are performed in the electric furnace steelmaking and the RH/VOD refining process based on the Cu removal principle of selective chlorination by high-oxygen-potential microcells manufactured in electric furnace steelmaking molten pool and on the RH/VOD refined steel liquid level and the high-vacuum smelting environment in the RH/VOD refining process fully utilized; the cost is low, the copper removing efficiency is high, and large-scale industrial production are facilitated.
