I-electrode yegraphite yinxalenye ebalulekileyo ye-EAFsteelmaking, kodwa ibala kuphela iqhezu elincinci leendleko zentsimbi.Kuthatha i-2 kg ye-graphite electrode ukuvelisa itoni yentsimbi.
Kutheni usebenzisa i-graphite electrode?
I-electrode yegraphite yeyona nto iphambili yokufudumeza i-conductor fittings ye-arc furnace.Ii-EAFs inkqubo yokunyibilika kwenkunkuma kwiimoto ezindala okanye kwizixhobo zekhaya ukuvelisa intsimbi entsha.
Ixabiso lokwakhiwa kwesithando sombane se-arc sisezantsi kunesithando somlilo esiqhelekileyo.Iziko lemveli lokuqhushumba zenza intsimbi kwintsimbi ekrwada kwaye zisebenzisa amalahle okucokisa njengamafutha.Nangona kunjalo, iindleko zokwenza intsimbi ziphezulu kwaye ungcoliseko lokusingqongileyo lunzulu.Nangona kunjalo, i-EAF ISEBENZISA intsimbi elahliweyo kunye nombane, nto leyo engachaphazeli indalo esingqongileyo.
I-electrode yegraphite isetyenziselwa ukudibanisa i-electrode kunye nesigqubuthelo sesithando somlilo siphelele, kwaye i-electrode yegraphite inokusebenza phezulu naphantsi.I-current idlula kwi-electrode, yenze i-arc yobushushu obuphezulu obunyibilikisa intsimbi ye-scrap.Ii-electrode zinokufikelela kwi-800mm(2.5ft) ububanzi kwaye ziye kuma-2800mm(9ft) ubude.Obona bunzima bungaphezulu kweetoni ezimbini zeemetric.
Ukusetyenziswa kwe-electrode yegraphite
Kuthatha iikhilogram ezi-2 (4.4 pounds) zegraphite electrode ukuvelisa itoni yentsimbi.
Ubushushu be-electrode yegraphite
Incam ye-electrode iya kufikelela kuma-3 000 ngokukaCelsius, isiqingatha sobushushu belanga.I-electrode yenziwe ngegraphite, kuba igraphite kuphela inokumelana nobushushu obunjalo.
Emva koko jikela iziko kwicala layo kwaye ugalele intsimbi etyhidiweyo kwimiphanda emikhulu.Ileyile ke iye iyise intsimbi etyhidiweyo kwindawo yokusila yentsimbi, nto leyo eguqula inkunkuma esetyenzisiweyo ibe yimveliso entsha.
I-electrode yegraphite idla umbane
Le nkqubo ifuna umbane owaneleyo ukunika amandla idolophu enabantu abayi-100,000.Kwisithando sombane se-arc yanamhlanje, ukunyibilika ngakunye kuthatha imizuzu engama-90 kwaye kunokuvelisa iitoni ezingama-150 zentsimbi, ezaneleyo ukwenza iimoto ezingama-125.
Impahla engekasilwa
Inaliti ye-coke yeyona nto iphambili ye-electrode, ethatha ukuya kwiinyanga ezintathu ukuya kwezintandathu ukuvelisa.Inkqubo ibandakanya ukugcadwa kunye nokuzala kwakhona ukuguqula icoke ibe yigraphite, utshilo umenzi.
Kukho inaliti esekwe kwipetroleum kunye necoke yenaliti esekwe emalahleni, zombini ezinokuthi zisetyenziswe ukuvelisa iielectrode zegraphite."I-Pet coke" yimveliso yenkqubo yokucoca i-petroleum, ngelixa i-coke-to-coke yenziwe kwi-tar yamalahle eyenzeka ngexesha lenkqubo yokuvelisa i-coke.
