I-graphite crucibleszaziwa ngokusebenza kwazo okuhle kakhulu kwe-thermal kanye nokumelana nokushisa okuphezulu. I-coefficient yabo ephansi yokwanda okushisayo ibavumela ukuthi bamelane nokushisa nokupholisa ngokushesha. Ziphinde zibonise ukumelana nokugqwala okuqinile kuzixazululo ze-asidi ne-alkaline, okubonisa ukuzinza okuhle kakhulu kwamakhemikhali. Kwezokusansimbi, ukuphonsa, emishinini, embonini yamakhemikhali nakweminye imikhakha yezimboni, isetshenziswa kakhulu ekuncibilikiseni insimbi yensimbi eyingxubevange, izinsimbi ezingenayo insimbi nama-alloys azo, futhi inezinzuzo ezinhle zobuchwepheshe nezomnotho. Umkhiqizi olandelayo wemikhiqizo ye-graphite ye-Haoyu uzokwethula izinyathelo zokuphepha lapho usebenzisa i-graphite crucible. Izexwayiso: Bamba ngokucophelela ngesikhathi sokuhamba ukuze ugweme ukulimala kokumboza phezulu futhi ugweme ukugingqika. Gcina endaweni eyomile ukuze uvimbele umswakama. Uma isetshenziswa kuhhavini we-coke, okuphansi kufanele kube isisekelo se-crucible esinobubanzi obukhudlwana kancane kunobubanzi obuphansi be-crucible ukunikeza ukusekela okufanele. Uma ilayishwa esithandweni somlilo, i-crucible akumele inyakaze, futhi ukuvuleka okuphezulu akufanele kube ngaphezu komlomo wesithando somlilo. Uma izitini zokusekela zisetshenziswa phakathi kokuvula phezulu kwe-crucible kanye nodonga lwesithando somlilo, izitini kufanele zibe phezulu kunokuvulwa kwe-crucible. Isisindo sesembozo sesithando somlilo kufanele sibe odongeni lwesithando somlilo. Ubukhulu be-coke esetshenzisiwe kufanele bube buncane kunegebe phakathi kodonga lwesithando somlilo kanye ne-crucible. Kufanele zengezwe ngokuwa mahhala ukusuka ekuphakameni okungenani okungama-5 cm futhi akufanele zithengwe. Ngaphambi kokusetshenziswa, i-crucible kufanele ishiswe kusuka ekamelweni lokushisa kuya ku-200 ° C amahora angu-1-1.5 (ikakhulukazi lapho kushisa okokuqala, i-crucible kumele iguqulwe ngokuqhubekayo ukuze kuqinisekiswe ukuthi ngaphakathi nangaphandle kwe-crucible kuyashiswa ngokulinganayo, futhi izinga lokushisa eliphakeme kakhulu liyi-100 ° C). Ngemva kokupholisa kancane nokukhipha isitimu, qhubeka nokushisa). Yabe isishisiswe cishe ku-800°C ihora elingu-1. Isikhathi sokubhaka akufanele sibe side kakhulu. (Uma ukushisa kwangaphambili okungafanele kubangela ukuxebuka nokuqhekeka, akuyona inkinga yekhwalithi, futhi inkampani yethu ayinasibopho ngembuyiselo.) Izindonga zesithando somlilo kufanele zigcinwe zinjalo ukuze kuvinjelwe ukuchezuka kwelangabi. Uma i-burner isetshenziselwa ukushisa, ilangabi akufanele lifuthwe ngokuqondile ku-crucible, kodwa phansi kwe-crucible. Izindlawu ezifanele ze-crucible kufanele zisetshenziselwe ukuphakamisa nokulayisha. Uma ulayisha insimbi, ungqimba lwezicucu kufanele lusatshalaliswe phansi ngaphambi kokufaka ingot yensimbi. Kodwa insimbi akufanele ibekwe iqine kakhulu noma izinga njengoba lokhu kungase kubangele ukuqhekeka kwe-crucible ngenxa yokwanda kwensimbi. Ukuncibilika okuqhubekayo kunciphisa isikhathi phakathi kwama-crucibles. Uma ukusetshenziswa kwe-crucible kuphazamiseka, uketshezi olusele kufanele lukhishwe ukuze kugwenywe ukuphuka uma luqalwa kabusha. Ngesikhathi senqubo yokuncibilikisa, inani le-ejenti yokucwenga kufanele lilawulwe ngokuqinile. Ukusetshenziswa ngokweqile kuzofinyeza impilo ye-crucible. I-slag eqoqiwe kufanele isuswe njalo ukuze kugwenywe ukushintsha ukuma nomthamo we-crucible. Ukwakheka kwe-slag ngokweqile nakho kungabangela ukuthi phezulu kukhukhumale futhi kuqhekeke. Ngokulandela lezi zinyathelo zokuphepha, ungaqinisekisa ukusebenza okuphelele nempilo ye-graphite crucible yakho.
