Emkhakheni wezinqubo zezimboni,i-graphitei-graphite silicon carbide crucible idlala indima ebalulekile ekusetshenzisweni okuhlukahlukene njenge-metallurgy, i-Foundry kanye namalabhorethri amakhemikhali. Ukuqinisekisa ukusebenza kahle kanye nokuhlala isikhathi eside kwalawa mathuluzi abalulekile, kufanele kulandelwe indlela yokunakekela ebanzi.
Okokuqala futhi okubaluleke kakhulu, ukugcinwa kwegraphitei-graphite silicon carbide crucible kudinga ukunakwa ngokucophelela. Lezii-graphite silicon carbide crucible kufanele igcinwe endaweni eyomile futhi ivikelwe emswakama ngaso sonke isikhathi. Kunconywa ukuwagcina ohlakeni olomile noma lokhuni ukuze unikeze isendlalelo esengeziwe sokuvikela. I-Fragility iyisici esichazayo se-graphitei-graphite silicon carbide crucible ngakho-ke kufanele kuphathwe ngokucophelela okukhulu ngesikhathi sokuthutha. Noma yiluphi uhlobo lomthelela noma ukudlidliza kufanele kugwenywe ngokuqinile ukuze kuvinjelwe umonakalo.
I-crucible kufanele ishiswe kancane kancane ibe ngu-500°C ngaphambi kokusetshenziswa. Uma ungeza izinto zokushisa, kubalulekile ukucabangela umthamo we-crucible futhi uqinisekise ukuthi inani elingeziwe liphakathi kwengxenye eyodwa kwezintathu kanye nezingxenye ezimbili kwezintathu zevolumu yayo yonke. Ngaphezu kwalokho, amathuluzi nezinsimbi ezisetshenziselwa ukuthulula kufanele zenziwe ngendlela oyifisayo ngokuvumelana nokuma kwe-crucible futhi zibe namandla okubamba afanele ukuvimbela noma yimuphi umonakalo.
Phakathi nenqubo yokwengeza izinto, kubalulekile ukulawula inani lezinto ezincibilikisiwe ku-crucible futhi ugweme ukugcwalisa noma ukuqinisa ngokweqile ukuvimbela ukwanda. Uma ususa i-slag ne-coke ezindongeni zangaphakathi nangaphandle ze-crucible, kunconywa ukuthi uthinte kancane ukuvimbela umonakalo. Ukubekwa okufanele ngaphakathi kwesithando somlilo nakho kubalulekile, nge-crucible egcinwe ebangeni elifanele ukusuka ezindongeni zesithando somlilo futhi ibekwe phakathi nendawo ukuze isebenze kahle.
Ukusetshenziswa okuqhubekayo kusiza i-crucible ukuthi ibonise ukusebenza kwayo okuphezulu. Kodwa-ke, amanani eqile ama-accelerators kanye nezithasiselo kufanele agwenywe ngoba anganciphisa kakhulu impilo yesevisi ye-crucible. Ukuze ukwandise impilo yesevisi ye-crucible, kunconywa ukuyijikeleza kanye ngesonto ngesikhathi sokusetshenziswa.
Ukwengeza, kubalulekile ukugwema ukujova okuqondile kwamalangabi e-oxidizing aqinile emaceleni nangaphansi kwe-crucible njengoba lokhu kungase kubangele umonakalo. Ngokunamathela kule mihlahlandlela yokulungisa, izikhungo zezimboni zingaqinisekisa isikhathi eside nokusebenza kahle kwegraphite yazoi-graphite silicon carbide crucible, ekugcineni kube nesandla ekusebenzeni kahle kwezinqubo nezinhlelo zokusebenza ezahlukahlukene.
