Sebenzisa i-induction melting furnace ngokuphepha futhi ugcine imikhuba emihle engu-7!

(1) Kaningi qaphela isimo sokuncibilika esithandweni somlilo. Inkokhelo kufanele ingezwe ngesikhathi ngaphambi kokuba inkokhelo incibilike ngokuphelele. Kutholakala ukuthi ukufakwa kwesikafula kufanele kulashwe ngesikhathi ukuze kugwenywe isithando somlilo ngenxa yokwenyuka okukhulu kokushisa kwensimbi encibilikisiwe ngaphansi kweshede, okudlula indawo encibilikayo (isihlabathi se-quartz 1704 ℃). Ku

(2) Ngemuva kokuthi insimbi encibilikisiwe incibilike, i-slag kufanele isuswe futhi izinga lokushisa kufanele lilinganiswe ngesikhathi, futhi insimbi encibilikisiwe kufanele ikhishwe ngesikhathi lapho ifinyelela emazingeni okushisa esithandweni somlilo. Ku

(3) Ngaphansi kwezimo ezijwayelekile, lapho udonga olubethelwayo luyi-1/3 yesikebhe sokuqala somugqa wesithando somlilo, isithando somlilo kufanele siqedwe futhi sakhiwe kabusha. Ku

(4) Insimbi encibilikisiwe kufanele ichithwe kanye ngesonto ukukala ubukhulu besithambo sesithando somlilo futhi ibheke isimo sayo sobuso, ukuqonda isimo sangempela sentambo yesithando somlilo ngesikhathi, nokubhekana nanoma yiziphi izinkinga ngesikhathi. Ku

(5) I-recarburizer yengezwa kancane kancane ngenkathi kwenziwa inqubo yokwengeza imali ekhokhwayo yensimbi. Ukungeza kusenesikhathi kuzonamathela ezansi kwesithando somlilo futhi ngeke kuncibilike kalula ensimbi ebunjiweyo. Ukungeza sekwedlule isikhathi kuzokwengeza isikhathi sokuncibilika nokushisa, okungezukubangela kuphela ukubambezeleka kokulungiswa kokwakhiwa, kepha futhi kungadala amazinga okushisa aphezulu ngokweqile. Ukwengezwa kwe-ferrosilicon (khuphula i-Si), okokufaka okuncibilikisayo kwamandla anamandla ashukumisayo, ngoba okuqukethwe okuphezulu kwe-Si kusimbi encibilikisiwe kuzodala ukwanda kwe-C, kungcono ukufaka i-Si iron ngokuhamba kwesikhathi, kepha kuzodala insimbi esithandweni somlilo . Ukubambezeleka ekuhlaziyweni nokwakhiwa ketshezi. Ku

(6) Ukushiya insimbi ewuketshezi esithandweni somlilo ngesikhathi sokuncibilika kungasiza ekuthuthukiseni ukusebenza kahle kukagesi kweminye imishini yokubasa kagesi futhi kuthuthukise amandla esigaba sokuncibilika. Kodwa-ke, lezi zinsimbi ezincibilikisiwe zingashiswa esithandweni isikhathi eside futhi zibeke engcupheni ikhwalithi yensimbi. Ngakho-ke, insimbi encibilikisiwe eseleyo kufanele ibe ne-15% yevolumu yesithando somlilo. Insimbi encanyana kakhulu encibilikisiwe izobhebhethekisa isimo esishisa ngokweqile, futhi insimbi eningi kakhulu encibilikisiwe izonciphisa ukusetshenziswa ngempumelelo kwensimbi encibilikile futhi inyuse ukusetshenziswa kwamandla eyunithi. Ku

(7) Ubukhulu benkokhiso bungaba ngu-200 ～ 300mm. Ukukhula okukhulu, ukuncibilika kancane.
