Isingeniso se-electrode ye-Graphite

I-electrode ye-graphiteIsetshenziswa kakhulu ekwenzeni insimbi ye-EAF. Ukwenza insimbi yesithando sikagesi kuhilela ukusebenzisa i-graphite electrode ukufaka ugesi esithandweni. Ugesi onamandla ukhiqiza ukukhishwa kwe-arc ngegesi ekugcineni okuphansi kwe-electrode, futhi ukushisa okukhiqizwa yi-arc kusetshenziselwa ukuncibilikisa. Ngokwekhono lesithando sikagesi, kusetshenziswa ama-electrode e-graphite anobubanzi obuhlukene. Ukuze kwenziwe ama-electrode asetshenziswe njalo, ama-electrode axhunywe yi-joint enentambo ye-electrode.i-electrode ye-graphiteUkwenza insimbi kubalwa u-70-80% wenani eliphelele le-graphite electrode. 2、 Isetshenziswa esithandweni samandla okushisa semayini. Isici sayo ukuthi ingxenye engezansi ye-electrode eqhubayo ingcwatshwe ekushajweni. Ngakho-ke, ngaphezu kokushisa okukhiqizwa yi-arc phakathi kwepuleti kagesi kanye nokushaja, ukushisa kukhiqizwa futhi ukumelana nokushaja lapho ugesi udlula ekushajweni. 3、 Isithando somlilo se-Graphitization, isithando sokuncibilikisa ingilazi kanye nesithando sikagesi sokukhiqiza imikhiqizo ye-graphite konke kuyizithando zokumelana. Izinto ezikusothandweni azigcini nje ngokumelana nokushisa, kodwa futhi ziyinto yokushisa. Ngokuvamile, i-electrode ye-graphite eqhubayo ifakwa odongeni lwekhanda lesithando ekugcineni kweziko, ngakho-ke i-electrode eqhubayo ayisetshenziswa njalo.

Izinkambu zohlelo lokusebenza:

(1) Isetshenziswa esithandweni sokwenza insimbi se-arc kagesi, esiwumsebenzisi omkhulu wei-electrode ye-graphite. EShayina, umkhiqizo wensimbi ye-EAF ubiza cishe u-18% womkhiqizo wensimbi engahluziwe, kanti i-graphite electrode yokwenza insimbi ibiza u-70% ~ 80% wokusetshenziswa okuphelele kwe-graphite electrode. Ukwenza insimbi yesithando sikagesi ukusebenzisa i-graphite electrode ukufaka ugesi esithandweni, bese kusetshenziswa umthombo wokushisa okushisa okuphezulu okhiqizwa yi-arc phakathi kokuphela kwe-electrode kanye nokushaja ukuze kuncibilike.

2) Isetshenziswa esithandweni se-arc esingaphansi komhlaba; isithando se-arc esingaphansi komhlaba sisetshenziswa kakhulu ekukhiqizeni i-silicon yezimboni kanye ne-phosphorus ephuzi, njll. Sibonakala ngokuthi ingxenye engezansi ye-electrode eqhubayo igqitshwe ekushajweni, yakha i-arc engqimbeni yokushaja, futhi ifudumale ishaja ngokusebenzisa amandla okushisa akhiqizwa ukumelana neshaja ngokwayo. Isithando se-arc esingaphansi komhlaba esine-current density ephezulu sidinga i-graphite electrode, isibonelo, i-graphite electrode engaba ngu-100kg iyadingeka ekukhiqizweni kwe-silicon engu-1t ngayinye, futhi i-graphite electrode engaba ngu-100kg iyadingeka ekukhiqizweni kwe-silicon engu-1t ngayinye. Cishe i-graphite electrode engu-40 kg iyadingeka ekushiseni i-phosphorus ephuzi engu-t.

(3) Isetshenziselwa isithando somlilo sokumelana; isithando somlilo se-graphitization sokukhiqiza imikhiqizo ye-graphite, isithando somlilo sokuncibilikisa ingilazi kanye nesithando sikagesi sokukhiqiza i-silicon carbide konke kungokwesithando somlilo sokumelana. Izinto ezikuso ziwukumelana nokushisa kanye nento efudumele. Ngokuvamile, i-electrode ye-graphite eqhubayo ifakwa odongeni lwekhanda lesithando ekugcineni kwesithando somlilo sokumelana, futhi i-electrode ye-graphite esetshenziswa lapha ayisetshenziswa njalo.

(4) Isetshenziselwa ukulungiselela okunesimo esikhethekileimikhiqizo ye-graphite; isikhala esingenalutho se-graphite electrode sisetshenziselwa futhi ukucubungula imikhiqizo ehlukahlukene ye-graphite enesimo esikhethekile njenge-crucible, isikhunta, isitsha sesikebhe kanye nomzimba wokushisa. Isibonelo, embonini yengilazi ye-quartz, kudingeka i-graphite electrode engu-10t engenalutho kuyo yonke ipayipi yokuncibilikisa kagesi engu-1t; i-graphite electrode engu-100kg engenalutho iyadingeka kuyo yonke i-quartz brick engu-1t.
