Development Status of High-efficiency Energy-saving Technology for Electric Arc Furnace Steelmaking
At present,China's steel industry,as the manufacturing industry with the highest carbon emissions,is still dominated by the blast-converter long process,which makes China's steel industry to achieve carbon neutrality facing great challenges.Compared with the long process of blast-converter steel making,the carbon emission of the short process of EAF steel making with scrap steel as the main raw material and electric power as the energy medium is about 1/3 of that of the long process of blast-converter,which has a good carbon reduction effect.And with the rising demand for environmental protection and the supply of scrap steel in China,at the same time by the national"14th Five-Year Plan"arc furnace development policy,under the background of the national"carbon peak,carbon neutral",the advantages of low energy consumption and less carbon emission of short process arc furnace steelmaking are becoming more and more obvious,and the future arc fur-nace short process steelmaking process will move faster toward efficient energy saving and green production.It has gradually become an impor-tant steelmaking process in China.From the perspective of energy saving and consumption reduction,this paper summarizes the development of high efficiency and energy saving technology of short-process electric arc furnace steelmaking at home and abroad,introduces its characteristics and development status.
