摘　　要：发展电弧炉短流程炼钢是钢铁工业实现“双碳”目标的重要途径。近年来,现代电弧炉技术发展迅速,电弧炉底吹搅拌技术也在不断进步和推广,对电弧炉生产的高效化和节能化作出了重要贡献。针对电弧炉底吹搅拌技术的机理、工艺特点、系统组成、气体种类、底吹元件类型及工艺布置方式进行综述,并对底吹技术的应用情况进行总结分析。模拟计算得出,远离底吹装置的区域,钢液流速明显偏低。结合炉型特点布置底吹装置及优化底吹气量,可改善熔池动力学条件,促进钢液元素传质,实现降低能耗和原材料消耗、提高生产效率的效果。深度开展底吹技术研发,与吹炼、供电、喷粉等工艺技术耦合,并结合新炉型特点制定底吹工艺制度,实现智能化底吹是发展现代电弧炉短流程技术的重要方向。The development of electric arc furnace(EAF)short process steelmaking is an important way for the iron and isdtelye,l iannddu sthtrey btoo trteoamli-zbel otwhein ggo satli rorfi n"gd oteucbhlen oclaorgbyo nof".E AInF r iesc aelnsto y peraorgsr,e sthsien mg oadnedr nb eEinAgF p treocmhontoeldo,gy w hhaisc hb emeank dees vaenlo ipminpgo rrtaapn⁃t cceosnst ricbhuatriaocnt etroi stthiec sh,i gshy setfefmic iecnomcyp aonsidti oenn,er ggya ss atyvpineg,ibno pttroomdu bcltoiowni nwgi tehl eEmAeFn.t tTyhpies apnadp eprr osucemsms aarrirzaensg tehmee mnte cohf atnhies mel,e cptrroic⁃raartce fuofr nmaoclet,e na nstde eslu mis moabrviizoeuss tlhy el oawp pinli ctahteio anr eoaf tfhare abwotatyo mfr obmlo wthien gb otettcohmn oblologwyi.n gS idmeuvliacteio.n B cya lacruralantgioinngs tshheo wbso ttthoamt tbhleo wflionwg fdeecvtiicvee layn edn ohpatnimcei ztihneg tdhyen vaomluicm ceo onfd bitoiottnosm o bf lothwei nmg oglatesn i np cooonl,ju fnacctiilointa twei tthh eth me afusrsn tarcaen scfhear raocf teelreismtiecnst,s iwt iitsh pino stshibe lem tool teefn⁃sTtheeerle,f othree,re ibt yc aanch bieev iinnfge rtrheed gtohaalt ocfo nredduucctiinngg reenseeragryc ha,n dc ormawb imniantge rdiaiflf ecroennstu tmecphtinoinq,u easn sdu ecnhh aasn cbilnogw ipnrgo,d upcotwioenr seuffpicpileyn acnyd.pwoewlld aesr irnejaelciztiionng,i nfotermlliugleantitn bgo bttootmto mb lbowloiwnign ga rper oimcepsosr tsaynstt edmir aeccctioorndsi nfgo rt ot hteh ed cehvealroapcmteerinstt icosf sohf odritf fperreoncet snse wst efeulrmnaackeins,g aosf modern EAF.
