Kwinkalo yeenkqubo zoshishino,igraphitei-graphite silicon carbide crucible zidlala indima ebalulekileyo kwizicelo ezahlukeneyo ezifana nesinyithi, isiseko kunye neelebhu zekhemikhali. Ukuqinisekisa ukusebenza ngokugqibeleleyo kunye nokuphila ixesha elide kwezi zixhobo zibalulekileyo, irejimeni yolondolozo olubanzi kufuneka ilandelwe.
Okokuqala nokuphambili, ukugcinwa kwegraphitei-graphite silicon carbide crucible kufuna ingqalelo ekhethekileyo. Ezii-graphite silicon carbide crucible kufuneka igcinwe kwindawo eyomileyo kwaye ikhuselwe ekufumameni ngamaxesha onke. Kunconywa ukuba uzigcine kwisakhelo esomileyo okanye sokhuni ukubonelela ngoluhlu olongezelelweyo lokukhusela. I-fragility luphawu olucacileyo lwegraphitei-graphite silicon carbide crucible kwaye ke ngoko kufuneka iphathwe ngenkathalo egqithisileyo ngexesha lothutho. Naluphi na uhlobo lwempembelelo okanye ukungcangcazela kufuneka kuphetshwe ngokungqongqo ukukhusela umonakalo.
I-crucible kufuneka ifudunyezwe ngokuthe ngcembe ukuya kwi-500°C ngaphambi kokusetyenziswa. Xa ufaka izinto zokufudumeza, kubalulekile ukuqwalasela umthamo we-crucible kwaye uqinisekise ukuba imali eyongeziweyo iphakathi kweyesithathu kunye neyesithathu kwisithathu somthamo wayo wonke. Ukongeza, izixhobo kunye neeclamps ezisetyenziselwa ukukhulula kufuneka zenziwe ngokwezifiso ngokwemilo ye-crucible kwaye ibe namandla afanelekileyo okubamba ukukhusela nawuphi na umonakalo.
Ngethuba lenkqubo yokongeza izinto eziphathekayo, kubalulekile ukulawula ubuninzi bezinto ezichithwe kwi-crucible kwaye ugweme ukugqithisa okanye ukuqinisa kakhulu ukukhusela ukwanda. Xa ususa i-slag kunye ne-coke kwiindonga zangaphakathi nangaphandle ze-crucible, kucetyiswa ukuba ucofe ngokukhawuleza ukukhusela umonakalo. Ukubekwa ngokufanelekileyo ngaphakathi kwesithando somlilo kubalulekile, kunye ne-crucible egcinwe kumgama ofanelekileyo ukusuka kwiindonga zesithando somlilo kwaye ibekwe phakathi kwendawo yokusebenza ngokufanelekileyo.
Ukusetyenziswa ngokuqhubekayo kunceda i-crucible ibonise ukusebenza kwayo okuphezulu. Nangona kunjalo, izixa ezigqithisileyo ze-accelerators kunye nezongezo kufuneka zigwenywe njengoko zinokunciphisa kakhulu ubomi benkonzo ye-crucible. Ukuze ukwandise ubomi benkonzo ye-crucible, kucetyiswa ukuba uyijikeleze kanye ngeveki ngexesha lokusetyenziswa.
Ukongeza, kubalulekile ukunqanda ukutofa ngokuthe ngqo kwamadangatye oxidizing anamandla emacaleni nasezantsi kwe-crucible njengoko oku kunokubangela umonakalo. Ngokuthobela ezi zikhokelo zokulondoloza, izibonelelo zoshishino zinokuqinisekisa ixesha elide kunye nokusebenza kakuhle kwegraphite yazoi-graphite silicon carbide crucible, ekugqibeleni igalelo ekusebenzeni kakuhle kweenkqubo ezahlukeneyo kunye nezicelo.
