Njengethuluzi elibalulekile ezimbonini ezinjengokuncibilikisa insimbi nezinye izinhlelo zokusebenza ezishisa kakhulu,ama-graphite cruciblesidlala indima ebalulekile ekuqukethe nasekushisiseni izinsimbi nama-alloys ahlukahlukene. Kodwa-ke, izimpilo zabo zesevisi bezikhawulelwe, lokho kungase kube nzima futhi kuphumele ezindlekweni ezengeziwe zabasebenzisi. Kulesi sihloko, sizohlola izindlela ezifanayo zokwandisa isikhathi sokuphilaama-graphite cruciblesfuthi andise ukuqina kwazo.
I-graphite crucibleszisetshenziselwa kakhulu ukuncibilika nokukhipha izinqubo, ngenxa ye-conductivity evelele yokushisa, ukumelana nokugqwala kanye nezakhiwo eziphikisayo. Nokho, ukuphila kwabo isikhathi eside kuncike ezicini eziningana, njengekhwalithi yezinto zokusetshenziswa, izinqubo zokukhiqiza, izimo zokusebenza, nezinqubo zokulondoloza. Ngakho-ke, kubalulekile ukukhetha ama-crucibles ekhwalithi ephezulu kubahlinzeki abathembekile futhi ulandele imihlahlandlela enconyiwe yokusetshenziswa nokunakekelwa kwabo.
Isici esisodwa esibalulekile esithinta isikhathi sokuphila se-graphite crucibles yinqubo yokushisisa nokupholisa. Ukushintsha okungazelelwe kwezinga lokushisa, okubuye kwaziwe njengokushaqeka kwe-thermal, kungaholela ekuqhekekeni, ekuqhekekeni, noma ekuwohlokeni kwama-crucibles, ekugcineni kunciphise impilo ende nokusebenza kwawo. Ukuze ugweme lezi zinkinga, kunconywa ukuthi kancane kancane futhi ngokulinganayo ushise kuqala ama-crucibles ngaphambi kokwengeza izinsimbi noma ama-alloys bese uzipholisa kancane kancane ngemva kokuba inqubo isiqediwe.
Esinye isici esibalulekile okufanele sicatshangelwe, okuwuhlobo lwensimbi noma i-alloy ecutshungulwayo. Izinsimbi ezithile, njenge-iron, i-nickel ne-cobalt, zingasabela nge-graphite emazingeni okushisa aphezulu futhi zenze i-carbides, engasheshisa ukuguga nokuqhekeka kwezinsimbi. Ukuze ugweme lokhu, kuhle ukusebenzisa izigqoko ezivikelayo noma ama-liners kuma-crucibles noma ukhethe amamaki e-graphite akhethekile aphikisana nokusabela okunjalo.
Ngaphezu kwalokho, ukunakekelwa okufanele kanye nokuhlanzwa kwezinsimbi kubalulekile futhi ekwandiseni isikhathi sabo sokuphila kanye nokuvimbela ukungcoliswa kwezinsimbi noma ama-alloys. Kunconywa ukuthi kuthululwe, kuphole, futhi kuhlanzwe izinsimbi ngemva kokusetshenziswa ngakunye usebenzisa amathuluzi afanele namakhemikhali ukuze kuqedwe noma yikuphi okusalayo noma ukungcola. Ukugcinwa ngendlela efanele kweziphambano endaweni eyomile nevikelekile nakho kubalulekile ukuze kuvinjwe ukulimala ngokomzimba noma ukumuncwa komswakama.
Ukufingqa, ukukhulisa isikhathi sokuphila se-graphite crucibles kudinga ukunamathela emikhubeni efanele nezinyathelo zokuphepha. Lokhu kuhlanganisa ukukhetha ama-crucibles ekhwalithi ephezulu, ukuwaphatha ngokucophelela, ukulawula inqubo yokushisisa nokupholisa, ukuwavikela ezinsimbi ezisasebenza, kanye nokuzinakekela njalo. Ngokwenza kanjalo, abasebenzisi bangonga isikhathi, imali, kanye nezinsiza ngenkathi beqinisekisa ukusebenza kwe-crucible okungaguquki nokuthembekile.
