Ubuchwepheshe bamandla aphezulu we-EAF buyinto esigxile kuyo ocwaningweni lwethu, amandla aphakeme kakhulu ayisici esivelele kakhulu sesizukulwane esisha semishini ye-EAF, ubuchwepheshe bokwenza insimbi yesithando somlilo esithuthukisiwe buqinisekisa izinga eliphezulu lomthamo wokukhiqiza kanye nekhwalithi, ukumiswa kwamandla e-EAF kuya phezulu. kuya ku-1500KVA/t insimbi encibilikisiwe okokufaka kwamandla aphakeme kakhulu, isikhathi esisuka ensimbi esiphuma ensimbi sicindezelwa sibe phakathi kwama-45min, ukuze kwenziwe ukwanda okukhulu komthamo we-EAF.
I-EAF isebenzisa ubuchwepheshe obusha bokushisisa okungavuthiwe, obunganciphisa izindleko zokukhiqiza futhi kwenyuse ukukhiqizwa. Ukugaywa kabusha okusebenzayo kwamandla okushisa ngo-100% wokushisa kwempahla eluhlaza kunciphisa ukusetshenziswa kwamandla kuze kube ngaphansi kuka-300KWh ngethani lensimbi.
I-EAF ingahlanganiswa nemishini ye-LF ne-VD ukuze kukhiqizwe izinhlobo zensimbi ezisezingeni eliphezulu kanye nensimbi engagqwali. Ukufakwa kwamandla aphezulu kakhulu kanye nokuphuma okuphezulu yizici eziyingqayizivele zalolu hlobo lokuncibilikisa kwesithando somlilo.
Ngokusekelwe kokuhlangenwe nakho kwethu okubanzi, singanikeza izixazululo eziningi ezithuthukile nezisebenzayo ze-EAF zokwenza insimbi.
Inqubo yokusebenza ye-EAF Electric Arc Furnace
Ngemva kokubeka ngokunembile izinsimbi ezilahliwe nezinto zensimbi ngaphakathi kwesithando somlilo kagesi, indlela yokuthungela i-arc iyasebenza ngokushesha, futhi amandla amanje anamandla ethulwa ngama-electrode aqhuba kahle kakhulu ukuze angene ngokunembile esakhiweni sensimbi nensimbi. Le nqubo incike emandleni okushisa okwedlulele akhishwe yi-arc ukuze kuzuzwe i-pyrolysis esebenzayo kanye nokuncibilika kwensimbi eyizinsimbi. Insimbi ewuketshezi ibe isibuthana phansi kwesithando somlilo, ilungele ukucwengwa okwengeziwe.
Phakathi nenqubo yokuncibilika, idivayisi yokufafaza amanzi ifutha inkungu yamanzi ukuze ilawule izinga lokushisa nomoya esithandweni somlilo. Enqubweni elawulwa kakhulu yokuncibilika, isistimu yokufafaza nge-ad hoc micro-mist ilawulwa ngokuguquguqukayo ngokuya nge-algorithms enembile, ukufafaza inkungu yamanzi kahle nangokufana, kusimamisa insimu yokushisa ngaphakathi kwesithando somlilo nokuthuthukisa indawo yokusabela kwamakhemikhali ngendlela yesayensi, iqinisekisa ukusebenza kahle okuphezulu nokuzinza kwenqubo yokuncibilika kanye nokuhlanzeka kwemikhiqizo.
Ngaphezu kwalokho, ekukhishweni kwegesi eyingozi etholakala ekusebenzeni kokuncibilika, uhlelo lufakwe imishini yokuhlanza igesi ephumayo esezingeni eliphakeme, yamukela ubuchwepheshe bokuhlanza okunezigaba eziningi, ukuqapha kwesikhathi sangempela kanye nokuguqula ngempumelelo kanye nokucubungula izingxenye eziyingozi kwigesi yokukhipha umoya, ngokuqinile. ukuthobela izindinganiso zokuvikela imvelo, kanye nokufeza isibopho sebhizinisi sokuvikelwa kwemvelo.
Izici ze-EAF Electric Arc Furnace
Isithando somlilo se-arc sikagesi se-EAF siqukethe igobolondo lesithando somlilo, isistimu ye-electrode, isistimu yokupholisa, iyunithi yokujova amanzi, iyunithi yokwelapha igesi ephumayo kanye nesistimu yokuphakela amandla. Igobolondo lesithando somlilo lenziwe ngepuleti lensimbi futhi limbozwe ngezinto eziphikisayo ukumelana nokushisa okuphezulu. Uhlelo lwe-electrode luhlanganisa ama-electrode aphezulu naphansi kanye nesibambi se-electrode. Ama-electrode axhunywe ohlelweni lokunikezwa kwamandla ngokusebenzisa abanikazi be-electrode, ngaleyo ndlela eqondisa amandla kagesi esithandweni somlilo. Isistimu yokupholisa isetshenziselwa ukugcina izinga lokushisa lama-electrodes kanye negobolondo lesithando somlilo ukuvimbela ukushisa ngokweqile Iyunithi yokufafaza amanzi isetshenziselwa ukufafaza inkungu yamanzi ukulawula ukupholisa kanye nomoya ngaphakathi kwesithando somlilo. Iyunithi yokwelapha igesi ephumayo isetshenziselwa ukwelapha amagesi ayingozi akhiqizwa ngesikhathi sokuncibilika.
Izithando zikagesi ze-EAF ziyakwazi ukuncibilikisa izinsalela nensimbi ngesikhathi esifushane, okuholela ekusebenzeni okuphezulu kokukhiqiza Uma kuqhathaniswa nezindlela ezijwayelekile zokwenza insimbi, i-EAF ingalawula inqubo yokuncibilika ngokunembe kakhudlwana ukuze ithole ingxubevange efunekayo.
