Kungani usebenzisa ama-electrode e-graphite? Izinzuzo kanye nokukhubazeka kwe-electrode ye-graphite

I-electrode ye-graphite iyingxenye ebalulekile yokwenza insimbi ye-EAF, kodwa iyingxenye encane kakhulu yezindleko zokwenza insimbi. Kuthatha ama-2 kg e-electrode ye-graphite ukukhiqiza ithani lensimbi.

Kungani usebenzisa ama-electrode e-graphite?

I-electrode ye-graphite iyizinto eziyinhloko zokufaka umqhubi wokushisa wesithando se-arc. I-EAFs inqubo yokuncibilikisa izingcezu zezimoto ezindala noma izinto zasekhaya ukuze kukhiqizwe insimbi entsha.
Izindleko zokwakha isithando sikagesi se-arc ziphansi kunesesithando sikagesi se-blast. Izithando zikagesi zendabuko zenza insimbi nge-iron ore futhi zisebenzisa amalahle okupheka njengophethiloli. Kodwa-ke, izindleko zokwenza insimbi ziphakeme futhi ukungcola kwemvelo kubi kakhulu. Kodwa-ke, i-EAF IYASEBENZISA insimbi elahliwe kanye nogesi, okungayithinti kangako imvelo.
I-electrode ye-graphite isetshenziselwa ukuhlanganisa i-electrode kanye nesembozo sesithando kube yi-furnace yonke, futhi i-electrode ye-graphite ingasebenza phezulu naphansi. Ugesi ube usudlula ku-electrode, wakhe i-arc yokushisa okuphezulu encibilikisa insimbi eqoshiwe. Ama-electrode angaba ububanzi obufika ku-800mm (2.5ft) futhi abe nobude obufika ku-2800mm (9ft). Isisindo esiphezulu singaphezu kwamathani amabili e-metric.

Ukusetshenziswa kwe-graphite electrode

Kuthatha amakhilogremu amabili (amakhilogremu angu-4.4) ama-electrode e-graphite ukukhiqiza ithani lensimbi.

Izinga lokushisa le-electrode ye-graphite

Isihloko se-electrode sizofinyelela kuma-degree Celsius angu-3,000, okuyisigamu sokushisa kwelanga. I-electrode yenziwe nge-graphite, ngoba yi-graphite kuphela engamelana namazinga okushisa aphezulu kangaka.
Bese uphendula isithando somlilo ohlangothini lwaso bese uthela insimbi encibilikisiwe emigqonyeni emikhulu. Iladle bese ihambisa insimbi encibilikisiwe ku-caster yefektri yensimbi, eguqula izingcezu ezisetshenzisiwe zibe umkhiqizo omusha.

I-electrode ye-graphite isebenzisa ugesi

Le nqubo idinga ugesi owanele ukunika amandla idolobha elinabantu abayi-100,000. Esithandweni sikagesi sesimanje, ukuncibilika ngakunye kuvame ukuthatha imizuzu engama-90 futhi kungakhiqiza amathani ayi-150 ensimbi, okwanele ukwenza izimoto eziyi-125.

Impahla eluhlaza

I-Needle coke iyinto eyinhloko yokusetshenziswa kwama-electrode, okuthatha izinyanga ezintathu kuya kweziyisithupha ukukhiqiza. Le nqubo ihilela ukuyosa nokufuthwa kabusha ukuze kuguqulwe i-coke ibe yi-graphite, kusho umenzi.
Kukhona i-needle coke esekelwe ku-petroleum kanye ne-needle coke esekelwe kumalahle, zombili ezingasetshenziswa ukukhiqiza ama-electrode e-graphite. I-“Pet coke” ingumkhiqizo ongaphansi kwenqubo yokucwenga i-petroleum, kuyilapho i-coal-to-coke yenziwa nge-coal tar eyenzeka ngesikhathi senqubo yokukhiqizwa kwe-coke.
