Ayini ama-electrode e-graphite ne-coke yenaliti?

Ama-electrode e-graphite ayisici sokushisa esiyinhloko esisetshenziswa esithandweni se-arc sikagesi, inqubo yokwenza insimbi lapho kuncibilika khona izingcucu ezisuka ezimotweni ezindala noma izinto zikagesi ukuze kukhiqizwe insimbi entsha.

Izithando ze-arc zikagesi zishibhile ukwakha kuneziqhumiso zendabuko, ezenza insimbi nge-iron ore futhi ezibaswa ngamalahle amalahle.Kodwa izindleko zokwenza insimbi ziphezulu njengoba zisebenzisa izinsalela zensimbi futhi zisebenza ngogesi.

Ama-electrode ayingxenye yesivalo sesithando somlilo futhi ahlanganiswe abe amakholomu.Ugesi ube usudlula kuma-electrode, enze i-arc yokushisa okunamandla okuncibilikisa insimbi elahliwe.Ama-Electrode ayahluka kakhulu ngosayizi kodwa angaba amamitha angu-0.75 (amafidi angu-2 nohhafu) ububanzi futhi afinyelele kumamitha angu-2.8 (amafidi angu-9) ubude.Isisindo esikhulu kunazo zonke singaphezu kwamathani amamethrikhi amabili.

Kuthatha kufika ku-3 kg (6.6 lb) wama-electrode e-graphite ukukhiqiza ithani elilodwa lensimbi.

Ichopho le-electrode liyofinyelela ku-3 000 degrees Celsius, okuyingxenye yokushisa kwelanga.Ama-electrode enziwe nge-graphite ngoba yi-graphite kuphela ekwazi ukumelana nokushisa okunamandla kangako.

Isithando somlilo sibe sesitshekelwa ohlangothini lwaso ukuze sithele insimbi encibilikisiwe emabhakedeni amakhulu abizwa ngokuthi ama-ladle.Amaleyidi abe esethwala insimbi encibilikisiwe ayiyise emshinini wokugaywa wensimbi, okwenza imikhiqizo emisha ngezicucu ezigaywe kabusha.

Ugesi odingekayo kule nqubo wanele ukunika amandla idolobha elinabantu abangu-100,000.Ukuncibilika ngakunye esithandweni sesimanje se-arc sikagesi ngokuvamile kuthatha cishe imizuzu engama-90 futhi kwenza amathani angu-150 ensimbi, anele izimoto ezingaba ngu-125.

I-needle coke iwumkhiqizo oyinhloko osetshenziswa kuma-electrode abakhiqizi abathi kungathatha izinyanga eziyisithupha ukuwenza ngezinqubo ezihlanganisa ukubhaka nokubhaka kabusha ukuze kuguqulwe i-coke ibe igraphite.

Kukhona inaliti ye-petroleum-based coke kanye ne-coke yenaliti esekwe emalahleni, futhi ingasetshenziswa ukukhiqiza ama-electrode e-graphite.I-'Pet coke' iwumkhiqizo ophuma ohlelweni lokucwenga uwoyela, kanti i-coke yenaliti esekelwe emalahleni yenziwa ngetiyela lamalahle elivela ngesikhathi sokukhiqiza i-coke.

Ngezansi kukhona abakhiqizi abahamba phambili emhlabeni bama-electrode e-graphite abalwa ngamandla okukhiqiza ngo-2016:
