I-graphite crucibles idume ngokuhambisa ukushisa okukhethekile kanye nokumelana nezinga lokushisa eliphezulu. I-coefficient yabo ephansi yokunwetshwa kwe-thermal ibanika amandla okumelana nokushisisa nokupholisa okusheshayo, okubenza bafanelekele izinhlelo zokusebenza ezinzima. Ngaphezu kwalokho, ukumelana kwabo okuqinile nama-acids abolayo kanye nezixazululo ze-alkaline, kuhambisana nokuzinza okuhle kakhulu kwamakhemikhali, kubenza bahluke ezimbonini ezihlukahlukene.
Kodwa-ke, ukusebenzisa ama-graphite crucibles kudinga ukunakwa ngokucophelela kuzinkombandlela ezithile ukuze kuqinisekiswe ukuphila kwabo isikhathi eside nokusebenza kahle. Nawa amaphuzu abalulekile okufanele uwacabangele:
Izinyathelo Zokuqapha Ngaphambi Kokusebenzisa:
Ukuhlolwa Kwezinto Ezibalulekile Nokulungiswa: Hlola ngokucophelela izinto ezizofakwa ku-crucible nganoma yiziphi izici eziqhumayo. Lapho ungeza izinto, qiniseka ukuthi zishisiwe futhi zomiswe ngokwanele. Uma wethula ama-graphite crucibles enqubweni, izinga lokufaka kufanele libe kancane kancane.
Ukuphatha Nokuthutha: Sebenzisa amathuluzi akhethekile okuthutha izinsimbi, ugweme ukugingqika okuqondile phansi. Ziphathe ngokucophelela ngesikhathi sokuthutha ukuze uvimbele ukulimala kokucwebezela, okungabeka engcupheni impilo ye-crucible.
Imvelo: Gcina indawo ezungezile yesithando somlilo futhi ugweme ukunqwabelana kwamanzi. Ungapakishi izinto ezingahlobene eduze nezinsimbi ze-graphite ukuze uvimbele noma yikuphi ukusebenzisana okungafunwa.
Ukufakwa Kwe-Crucible Nokulungiswa:
Okweziko Zegesi noma Kawoyela: Beka i-crucible esisekelweni, ushiye isikhala esithile sokunweba phakathi kwe-crucible top kanye nodonga lwesithando somlilo. Sebenzisa izinto ezinjengamabhulokhi okhuni noma amakhadibhodi aqinile ukuze uvikeleke endaweni. Lungisa indawo yokushisa kanye ne-nozzle ukuze uqinisekise ukuthi ilangabi liqondise igumbi elivuthayo, hhayi ngqo phansi kwe-crucible.
Kumafurnace ajikelezayo: Sebenzisa izitini zokusekela kuzo zombili izinhlangothi ze-spout yokuthulula i-crucible ukuze uyivikele, ngaphandle kokuqinisa kakhulu. Faka izinto ezifana nekhadibhodi, ubukhulu obungu-3-4mm, phakathi kwezitini ezisekelayo kanye ne-crucible ukuvumela ukunwetshwa kwangaphambili.
Okwezithando Zomlilo Kagesi: Beka i-crucible engxenyeni emaphakathi yesithando somlilo, nesisekelo saso sibe ngaphezu kancane komugqa ongezansi wezinto zokushisisa. Vala igebe phakathi kwengaphezulu le-crucible kanye nonqenqema lwesithando somlilo ngezinto ezivikelayo.
Kuma-Induction Furnaces: Qinisekisa ukuthi i-crucible igxile ngaphakathi kwekhoyili yokungeniswa ukuze uvikele ukushisa okweqile kwendawo kanye nokuqhekeka.
Ukunamathela kule mihlahlandlela kuqinisekisa ukusetshenziswa okuphephile nokusebenza kahle kwe-graphite crucibles, okuthuthukisa impilo ende yama-crucibles kanye nokusebenza kahle okuphelele kuzinhlelo zokusebenza ezisezingeni eliphezulu.
Ukuze uthole imiyalelo enemininingwane eminingi nokwesekwa, abasebenzisi bayakhuthazwa ukuthi babheke imihlahlandlela yomkhiqizi futhi baxhumane nochwepheshe bemboni.
