Impilo yesevisi yegraphite silicon carbide crucibleskuyisici esibalulekile okufanele sicatshangelwe lapho uzisebenzisa ezinhlelweni ezahlukahlukene zezimboni. Lawa ma-crucibles asetshenziswa kakhulu ezinqubweni zokuncibilikisa nokuphonsa ezimbonini ze-metallurgical kanye ne-Foundry. Ukuqonda izici ezithinta impilo yesevisi yalezi ziphambano kubalulekile ukuze kuthuthukiswe ukusebenza kwazo nokuqina.
Izinga lokushisa elisebenzayo lidlala indima ebalulekile ekunqumeni impilo yesevisi ye-graphite silicon carbide crucibles. Ukuphakama kwezinga lokushisa lokusebenza, impilo yesevisi ye-crucible iyancipha. Lokhu kungenxa yokuthi ama-crucibles abhekana nengcindezi enkulu yokushisa emazingeni okushisa aphezulu futhi maningi amathuba okuthi aphuke. Kubalulekile ukusebenzisa ama-crucibles ngaphakathi kwebanga lokushisa elinconywayo ukuze uqinisekise impilo yesevisi eyandisiwe futhi uvimbele ukwehluleka ngaphambi kwesikhathi.
Inombolo yokusetshenziswa izophinde ithinte impilo yesevisi ye-graphite silicon carbide crucible. Ngemuva kokusetshenziswa ngakunye, ama-crucibles angaphansi kokugqoka nokugqwala, okwenza impilo yabo yesevisi yehle kancane kancane. Imvamisa yokusetshenziswa ithinta ngqo impilo yesevisi ye-crucible, ngakho-ke kubalulekile ukuqapha nokuhlola isimo se-crucible ngemva komjikelezo ngamunye. Ukunakekelwa okufanele kanye nokuhlolwa okuvamile kungasiza ekunwebiseni impilo ye-crucible yakho futhi kuqinisekise ukusebenza okude, okuzinzile.
Indawo yamakhemikhali lapho i-crucible isetshenziswa khona inomthelela omkhulu empilweni yayo yesevisi. I-graphite silicon carbide crucibles ibonisa amazinga ahlukene okumelana nokugqwala ezindaweni ezihlukene zamakhemikhali. Ukuchayeka ezintweni ezonakalisayo kuzosheshisa ukuwohloka kwe-crucible, okuholela empilweni yesevisi ibe mfushane. Kubalulekile ukukhetha izinto ezifanele ze-crucible ngokusekelwe endaweni ethile yamakhemikhali lapho i-crucible izosetshenziswa khona ukuze kuqinisekiswe ukusebenza kahle nokuphila isikhathi eside.
Indlela i-crucible esetshenziswa ngayo nayo ithinta impilo yayo yesevisi. Ukusetshenziswa okungafanele, njengokufaka i-crucible ekushintsheni okungazelelwe kwezinga lokushisa noma ukubeka izinto ezibandayo kuyo, kungalimaza ukuqina kwayo. Ukuphatha ngendlela efanele kanye nokuhambisana nezinqubo zokusebenza ezinconyiwe kubalulekile ekwandiseni impilo ebucayi kanye nokuvimbela ukwehluleka ngaphambi kwesikhathi.
Ukunamathela kanye nokwakheka kwezingqimba ze-oxide ngaphakathi kwe-crucible nakho kungathinta ukusebenza kwayo nokuphila kwesevisi. Lezi zici zingaphazamisa ikhono le-crucible ukumelana namazinga okushisa aphezulu kanye nezindawo ezibolayo, okuholela ekuphileni okufushane. Ukuhlanza njalo nokunakekela kungasiza ekwehliseni imiphumela yokunamathela kanye nokwakheka kwe-oxide, kusize ukwelula impilo ye-crucible yakho.
Lapho uhlola impilo yesevisi ye-graphite silicon carbide crucibles, kubalulekile ukucabangela isicelo esithile kanye nezimo zokusebenza. Impilo yangempela yesevisi ingase ihluke kuye ngezinto ezifana nendlela yokusetshenziswa, izinga lokushisa, indawo yamakhemikhali, kanye nemvamisa yokusetshenziswa. Ukuhlola okuphelele nokuhlola endaweni yokusebenza okuhlosiwe kunganikeza imininingwane ebalulekile empilweni yesevisi elindelwe ye-crucible.
I-graphite silicon carbide crucibles yethu iklanyelwe ukuhlinzeka ngokusebenza okuthembekile nempilo yesevisi eyandisiwe ezinhlelweni zokuncibilika ezihlukahlukene. Uma isetshenziselwa ukuncibilikisa i-aluminium, ama-crucibles ethu ahlinzeka impilo yesevisi yezinyanga ezingu-6-7, kuyilapho lapho esetshenziselwa ukuncibilikisa ithusi, impilo yesevisi cishe yizinyanga ezi-3. Ngokunaka ngokukhethekile ukusetshenziswa, amazinga okushisa okusebenza kanye nemvelo yamakhemikhali, ama-crucibles ethu angakhulisa impilo yawo yesevisi, anikeze ukusebenza okungaguquguquki, okuphumelelayo kwezinqubo zokuncibilika kwezimboni kanye nokuphonsa.
