High Carbon Ferrochrome Technology

Ikhabhoni ephezului-ferrochromeingenye yama-ferroalloys ajwayelekile akhiqizwayo futhi acishe asetshenziswe kuphela ekukhiqizeni insimbi engagqwali nezinsimbi ze-chromium eziphezulu.Ukukhiqizwa kwenzeka ikakhulukazi emazweni anokunikezwa kwe-chromite ore enkulu.Ugesi oshibhile kanye nezinto ezincishiswayo nazo zinomthelela ekusebenzeni kwekhabhoni ferrochrome ephezulu.Ubuchwepheshe obujwayelekile bokukhiqiza obusetshenziswayo ukuncibilika kwe-arc emanzini ashisayo ku-AC, nakuba ukuncibilika kwe-arc evulekile ezithandweni ze-DC kuya ngokuya kuvame.Umzila wobuchwepheshe obuthuthuke kakhulu ohlanganisa isinyathelo sokunciphisa kusengaphambili usetshenziswa kuphela ngezinga elibalulekile umkhiqizi oyedwa.Izinqubo zokukhiqiza seziphenduke amandla engeziwe kanye ne-metallurgical esebenza kahle ngokusebenzisa izinqubo ezithuthukisiwe ezifana nokunciphisa ngaphambi kwesikhathi, ukushisa kuqala, i-agglomeration ye-ore, kanye nokusetshenziswa kwegesi ye-CO.Izitshalo ezisanda kufakwa zibonisa ubungozi obulawulekayo mayelana nokungcoliswa kwemvelo nempilo yomsebenzi.

Ngaphezulu kwama-80% okukhiqizwa kwe-ferrochrome emhlabeni asetshenziswa ekukhiqizeni insimbi engagqwali.Insimbi engagqwali incike ku-chromium ngokubukeka kwayo kanye nokumelana nokugqwala.Isilinganiso sokuqukethwe kwe-chromium kunsimbi engagqwali ngu-18%.I-FeCr iphinde isetshenziswe uma ifunwa ukwengeza i-chromium kunsimbi ye-carbon.I-FeCr yaseNingizimu Afrika eyaziwa ngokuthi “i-chrome yokushaja” futhi ekhiqizwe ngensimbi ye-chrome yezinga eliphansi isetshenziswa kakhulu ekukhiqizeni insimbi engagqwali.I-FeCr enekhabhoni ephezulu ekhiqizwa kusukela ku-ore yezinga eliphezulu etholakala e-Kazakhstan (phakathi kwezinye izindawo) isetshenziswa kakhulu ezinhlelweni ezikhethekile ezifana nezinsimbi zobunjiniyela lapho isilinganiso esiphezulu se-Cr kuya ku-Fe sibalulekile.

Ukukhiqizwa kwe-Ferrochrome empeleni kuwumsebenzi wokunciphisa izinga lokushisa eliphezulu kwe-carbothermic.I-Chrome ore (i-oxide ye-chromium ne-iron) incishiswa nge-coke (namalahle) ukuze yakhe ingxubevange ye-iron-chromium-carbon.Ukushisa kwenqubo kunikezwa ngokujwayelekile kusukela ku-arc kagesi eyakhiwe phakathi kwamathiphu ama-electrode ngaphansi kwesithando somlilo kanye neziko lomlilo eziko ezinkulu ezingamacylindrical ezaziwa ngokuthi "izithando ze-arc ezicwilisiwe."Njengoba igama lisho ukuthi ama-electrode amathathu ekhabhoni yesithando somlilo acwiliswa embhedeni wengxube eqinile kanye nenye ye-liquid eyenziwe yikhabhoni eqinile (i-coke kanye/noma amalahle), izinto zokusetshenziswa eziqinile ze-oxide (i-ore kanye ne-fluxes) kanye uketshezi lwe-FeCr alloy namaconsi e-slag ancibilikisiwe akhiwayo.Enqubweni yokuncibilikisa, kusetshenziswa amanani amakhulu kagesi.Ukuthepha impahla evela esithandweni kwenzeka ngezikhathi ezithile.Uma i-ferrochrome eyanele encibilikisiwe isinqwabelene eziko lesithando, imbobo kampompi iyavulwa futhi umfudlana wensimbi encibilikisiwe kanye ne-slag kugeleza ku-trough kube kumakhaza noma i-ladle.I-ferrochrome iyaqina ekubunjweni okukhulu, okuchotshozwa ukuze kudayiswe noma kuqhutshekwe kucutshungulwe.
