Kungani usebenzise ama-electrode e-graphite? Izinzuzo kanye nokukhubazeka kwe-graphite electrode

I-electrode ye-graphite iyingxenye ebalulekile ye-EAFsteelmaking, kodwa ibala ingxenye encane yezindleko zokwenza insimbi. Kudingeka i-2 kg ye-graphite electrode ukukhiqiza ithani lensimbi.

Kungani usebenzise ama-electrode e-graphite?

I-graphite electrode iyisici esiyinhloko se-conductor yokushisa yesithando somlilo se-arc. Ama-EAFs inqubo yokuncibilikisa izinsalela ezimotweni ezindala noma izinto zasendlini ukuze kukhiqizwe insimbi entsha.
Izindleko zokwakha zesithando somlilo se-arc kagesi ziphansi kunesithando somlilo esivamile. Iziko lendabuko eliqhumayo zenza insimbi ngensimbi futhi zisebenzisa amalahle okuphekela njengophethiloli. Nokho, izindleko zokwenza insimbi ziphezulu futhi ukungcoliswa kwemvelo kubi kakhulu. Nokho, i-EAF ISEBENZISA izinsimbi ezilahliwe nogesi, okungayithinti neze indawo ezungezile.
I-electrode ye-graphite isetshenziselwa ukuhlanganisa i-electrode kanye nesembozo sesithando somlilo sibe siphelele, futhi i-electrode ye-graphite ingaqhutshwa phezulu naphansi. I-current ibe isidlula ku-electrode, yenze i-arc enezinga eliphezulu lokushisa encibilikisa insimbi eyizinsimbi. Ama-electrode angaba ngu-800mm(2.5ft) ububanzi futhi afinyelele ku-2800mm(9ft) ubude. Isisindo esiphezulu singaphezu kwamathani amamethrikhi amabili.

Ukusetshenziswa kwe-graphite electrode

Kudingeka amakhilogremu angu-2 (amakhilogremu angu-4.4) wama-electrode e-graphite ukukhiqiza ithani lensimbi.

Ukushisa kwe-graphite electrode

Ichopho le-electrode lizofinyelela ku-3,000 degrees Celsius, ingxenye yokushisa kwelanga okuyingxenye. I-electrode yenziwe nge-graphite, ngoba i-graphite kuphela ingakwazi ukumelana namazinga okushisa anjalo.
Bese uvula isithando somlilo ohlangothini lwaso bese uthela insimbi encibilikisiwe emiphongolweni emikhulu. Iladi libe selihambisa insimbi encibilikisiwe emshinini wokugaywa wensimbi, oguqula izinsalela ezigaywe kabusha zibe umkhiqizo omusha.

I-electrode yegraphite idla ugesi

Lolu hlelo ludinga ugesi owanele ukunika amandla idolobha elinabantu abangu-100,000. Esithandweni sesimanje se-arc sikagesi, ukuncibilika ngakunye ngokuvamile kuthatha imizuzu engu-90 futhi kungakhiqiza amathani angu-150 ensimbi, anele ukwenza izimoto ezingu-125.

Impahla eluhlaza

I-needle coke iwumthombo oyinhloko wama-electrode, athatha izinyanga ezintathu kuya kweziyisithupha ukukhiqiza. Inqubo ihilela ukugazinga kanye nokukhulelwa kabusha ukuze i-coke ibe i-graphite, kusho umenzi.
Kukhona i-coke yenaliti esekwe ku-petroleum ne-coke yenaliti esekwe emalahleni, zombili ezingasetshenziswa ukukhiqiza ama-electrode e-graphite. I-“Pet coke” iwumkhiqizo ophuma ku-petroleum refining, kuyilapho i-coke-to-coke yenziwa ngetiyela lamalahle eyenzeka phakathi nenqubo yokukhiqiza i-coke.
