Itekhnoloji yamandla aphezulu e-EAF yeyona nto kugxilwe kuyo kuphando lwethu, amandla aphezulu yeyona nto ibalaseleyo kwisizukulwana esitsha sezixhobo ze-EAF, itekhnoloji yokwenziwa kwentsimbi yombane ephucukileyo iqinisekisa elona nqanaba liphezulu lomthamo wemveliso kunye nomgangatho, ukumiselwa kwamandla e-EAF phezulu. ukuya kwi-1500KVA / t intsimbi etyhidiweyo ye-ultra-high igalelo lamandla, ixesha elivela kwintsimbi ephuma kwintsimbi licinezelekile ukuya kwi-45min, ukwenzela ukuba ukwanda okumandla kumthamo we-EAF.
I-EAF yamkela itekhnoloji entsha yokufudumeza, enokunciphisa iindleko zemveliso kunye nokunyusa imveliso. Ukurisayikilishwa okusebenzayo kwamandla obushushu nge-100% yokufudumeza kwemathiriyeli ekrwada kunciphisa ukusetyenziswa kwamandla ukuya ngaphantsi kwe-300KWh ngetoni nganye yentsimbi.
I-EAF inokudityaniswa kunye ne-LF kunye nezixhobo ze-VD ukuvelisa iindidi ezikumgangatho ophezulu wentsimbi kunye nentsimbi engenasici. I-ultra-high-power input kunye ne-high throughput yimpawu ezizodwa zolu hlobo lwesithando somlilo.
Ngokusekelwe kumava ethu abanzi, sinokunika uluhlu olubanzi lwezisombululo zentsimbi eziphambili nezisebenzayo ze-EAF.
Inkqubo yokusebenza ye-EAF Electric Arc Furnace
Emva kokubeka ngokuchanekileyo isinyithi esilahliweyo kunye nezixhobo zentsimbi ngaphakathi kwesithando sombane, i-arc ignition mechanism isebenze ngokukhawuleza, kwaye umbane onamandla ungeniswa ngokusebenzisa i-electrodes eqhuba kakhulu ukuba ingene ngokuchanekileyo kwisakhiwo sentsimbi kunye nentsimbi. Le nkqubo ixhomekeke kumandla obushushu obugqithisileyo akhutshwe yi-arc ukufezekisa i-pyrolysis esebenzayo kunye nokunyibilika kwentsimbi ye-scrap. Intsimbi engamanzi ke iqokelelana ezantsi kweziko, ilungele ukucocwa ngakumbi.
Ngethuba lenkqubo yokunyibilika, isixhobo sokutshiza amanzi sitshiza inkungu yamanzi ukulawula ubushushu kunye nomoya esithandweni. Kwinkqubo elawulwa kakhulu yokunyibilika, inkqubo yokutshiza ye-ad hoc micro-mist ilawulwa ngokuguquguqukayo ngokwe-algorithms echanekileyo, ukutshiza inkungu yamanzi ngokucokisekileyo nangokufanayo, ukuzinzisa intsimi yobushushu ngaphakathi kwesithando somlilo kunye nokwenza ngcono imekobume yokusabela kweekhemikhali ngendlela yesayensi, iqinisekisa ukusebenza kakuhle kunye nokuzinza kwenkqubo yokunyibilika kunye nokucoceka kweemveliso.
Ukongeza, ukukhutshwa kwerhasi eyingozi evela ekusebenzeni kokunyibilika, inkqubo ixhotyiswe ngezixhobo zokucoca igesi ephumayo, yamkele itekhnoloji yokucoca yamanqanaba amaninzi, ukubeka iliso ngexesha lokwenyani kunye nokuguqula ngokufanelekileyo kunye nokwenza izinto ezinobungozi kwigesi yokukhupha, ngokungqongqo. ukuthobela imigangatho yokhuseleko lokusingqongileyo, kunye nokuzalisekisa uxanduva lweshishini lokhuseleko lokusingqongileyo.
Iimpawu zeEAF Electric Arc Furnace
I-EAF electric arc furnace iqukethe igobolondo yomlilo, inkqubo ye-electrode, inkqubo yokupholisa, iyunithi yokutofa kwamanzi, iyunithi yokucoca igesi yokukhupha kunye nenkqubo yokubonelela ngombane. Igobolondo lesithando somlilo lenziwe ngepleyiti yensimbi kwaye igqunywe ngezinto eziphikisayo ukumelana nobushushu obuphezulu. Inkqubo ye-electrode ibandakanya i-electrode ephezulu nangaphantsi kunye nomphathi we-electrode. I-electrodes ixhunyiwe kwinkqubo yokunikezelwa kwamandla ngokusebenzisa abanikazi be-electrode, ngaloo ndlela iqondisa umbane wombane kwisithando somlilo. Inkqubo yokupholisa isetyenziselwa ukugcina ubushushu bee-electrodes kunye negobolondo lesithando somlilo ukukhusela ukufudumala Iyunithi yokutshiza amanzi isetyenziselwa ukutshiza inkungu yamanzi ukulawula ukupholisa kunye nomoya ngaphakathi kwesithando somlilo. Iyunithi yonyango yegesi yokukhupha isetyenziselwa ukuphatha iigesi ezinobungozi ezenziwe ngexesha lokunyibilika.
Iziko zombane ze-arc ze-EAF ziyakwazi ukunyibilikisa inkunkuma kunye nentsimbi ngexesha elifutshane, okukhokelela ekusebenzeni okuphezulu kwemveliso Xa kuthelekiswa neendlela eziqhelekileyo zokwenza intsimbi, i-EAF inokulawula inkqubo yokunyibilika ngokuchanekileyo ngakumbi ukufumana i-alloy efunekayo.
