I-graphite silicon carbide crucible, njengezingxenye ezibalulekile ezinqubweni ezihlukahlukene zezimboni, zibhekana nezinkinga ezingase zibe khona ngenxa yokusetshenziswa isikhathi eside. Ukuqhekeka kwe-longitudinal kwabonwa ezindongeni eziphambanisayo, okubonisa ukukhubazeka okungenzeka kwesakhiwo okungase kuphazamise ukusebenza nokuphepha kwayo.
Okunye okubhekiwe okuphathelene nokwakhiwa kokuqhekeka okukodwa okuyi-longitudinal okusuka phezulu konqenqema lwe-crucible. Lokhu kungase kwenzeke ngenxa yokushisa okusheshayo kwe-crucible, ikakhulukazi uma imiphetho engezansi nephansi ibhekene namazinga okushisa aphezulu kunaphezulu. Ukwengeza, ukusetshenziswa kodlawu lwe-crucible olungafanele noma umthelela onqenqemeni olungaphezulu lwe-ingot nakho kungaholela ekwakhekeni kwalokhu kuqhekeka.
Ukwengeza, ukuba khona kwemifantu ye-longitudinal eminingi ehambisanayo esuka emaphethelweni aphezulu e-crucible kuphakamisa ukukhathazeka okwengeziwe. Lesi senzakalo singase sihlotshaniswe nokucindezela okwenziwa ngokuqondile yisivalo somlilo ku-crucible noma ukuba khona kwegebe elibalulekile phakathi kwesivalo somlilo kanye ne-crucible. Lezi zimo zingaholela ekwandeni kwe-oxidation ye-crucible, ekugcineni kubangele ukuqhekeka futhi kuphazamise ubuqotho bayo besakhiwo.
Ngaphandle kokuqhekeka onqenqemeni oluphezulu, ukuqhekeka kwe-longitudinal nakho kwatholakala ezinhlangothini ze-crucible. Le mifantu ivamise ukudalwa ukucindezelwa kwangaphakathi, okuvamise ukubangelwa ukubeka inkaba epholile yento ephonswe eceleni ku-crucible. Ukunwetshwa kokubunjwa okumise okwe-wedge uma kushisisiwe kungafaka ingcindezi enkulu ku-crucible, okuholela ekuthuthukisweni kokuqhekeka kanye nokulimala okungaba khona kwesakhiwo.
Ukuba khona kwale mifantu kuyinkomba ecacile yokuthi i-crucible ingase isondele noma isifinyelele ekupheleni kokusebenza kwayo. Ukuncipha kodonga oluhlabayo ku-crack kuphinde kugqamise ukuthi i-crucible ingase ingakwazi ukumelana nengcindezi eyeqile, okubeka engcupheni enkulu kuyo yonke inqubo yezimboni lapho isetshenziswa khona.
Ukubhekana nalezi zinkinga kubalulekile ekuqinisekiseni ukuthi izinqubo zezimboni ezithembele kuzoi-graphite silicon carbide crucible qhubeka nokusebenza ngokuphepha nangempumelelo. Abaqhubi bezimboni kanye nabasebenzi abalungisa izinto kumele baqaphe ngokucophelela isimo sei-graphite silicon carbide crucible futhi uthathe izinyathelo ezisheshayo zokunciphisa ingozi yokwehluleka kwesakhiwo.
Iphrothokholi ejwayelekile yokuhlola kanye nokugcinwa kufanele isungulwe ukuze kutholwe izimpawu zakuqala zokuguga nokulimala kwe-crucible. Ukwengeza, amasu okushisa afanele kanye nokusetshenziswa kwemishini yokuphatha efanele (njengama-crucible tongs) kubalulekile ukuvimbela ukwakheka kwemifantu nokuqinisekisa ubude besikhathi se-crucible endaweni yezimboni.
Ukwengeza, ukuklama nokusebenza kwesithando somlilo kufanele kuhlolwe ngokucophelela ukuze kuncishiswe ukucindezela okuqondile ku-crucible nokuvimbela i-oxidation ngokweqile, okungaholela ekwakhekeni kwemifantu. Ukuthatha izinyathelo zokulawula ingcindezi yangaphakathi, ikakhulukazi uma usebenzisana nezinto ezikhula kakhulu lapho kushisa, kubalulekile ukuvikela i-crucible ekulimaleni kwesakhiwo.
Kafushane, ukuba khona kokuqhekeka kwe-longitudinal kui-graphite silicon carbide crucible idinga ukunakwa ngokushesha kanye nezinyathelo zokulungisa ukuvimbela izingozi ezingase zibe khona kanye nokuphazamiseka ezinqubweni zezimboni. Ngokubeka phambili ukugcinwa okuvamile, izinqubo zokuphatha okufanele kanye nokwenza ngcono ukusebenza kwesithando somlilo, izimboni zingakwazi ukuvikela ubuqotho bomsebenzi wazo.i-graphite silicon carbide crucible kanye nokugcina ukwethembeka kwemisebenzi yabo yokukhiqiza nokukhiqiza.
