I-graphite ye-silicon carbide crucible, njengamacandelo abalulekileyo kwiinkqubo ezahlukeneyo zoshishino, zijongene neengxaki ezinokubakho ngenxa yokusetyenziswa kwexesha elide. Ukuqhekeka kwe-longitudinal kwabonwa kwiindonga ze-crucible, ezibonisa iziphene ezinokuthi zenzeke ezinokuthi ziphazamise ukusebenza kwayo kunye nokhuseleko.
Olunye lwemigqaliselo ephathelele kuphuhliso lokuqhekeka okukodwa okude ukusuka kumda ongaphezulu wesibhodlo. Oku kunokwenzeka ngenxa yokufudumeza ngokukhawuleza kwe-crucible, ngakumbi xa imida engezantsi kunye nezantsi ibonakaliswe kumaqondo okushisa aphezulu kunaphezulu. Ukongezelela, ukusetyenziswa kweentambo ezingafanelekanga okanye impembelelo kumda ophezulu we-ingot kunokukhokelela ekubunjweni kwezi ziqhekeza.
Ukongezelela, ubukho bokuqhekeka kweelongitudinal ezininzi ezihambelanayo ukusuka kumda ophezulu we-crucible kuphakamisa inkxalabo eyongezelelweyo. Le nto inokuthi ihambelane noxinzelelo olwenziwa ngokuthe ngqo kwi-lid yesithando somlilo kwi-crucible okanye ubukho be-gap ebalulekileyo phakathi kwesivalo somlilo kunye ne-crucible. Ezi meko zingakhokelela ekunyuseni kwe-oxidation ye-crucible, ekugqibeleni ibangele ukuqhekeka kunye nokunciphisa ingqibelelo yayo yesakhiwo.
Ukongeza kokuqhekeka kwinqanaba eliphezulu, ukuchithwa kwe-longitudinal kwafunyanwa kwakhona kumacala e-crucible. Ezi ntanda ngokuqhelekileyo zibangelwa luxinzelelo lwangaphakathi, oluhlala lubangelwa ukubeka i-wedge epholileyo yezinto ezityhidiweyo ecaleni kwi-crucible. Ukwandiswa kwezinto zokuphosa ezimise okwe-wedge xa kushushu kunokubangela uxinzelelo olubalulekileyo kwi-crucible, ekhokelela ekuphuhlisweni kweentanda kunye nomonakalo onokuthi ube khona.
Ubukho bezi ntanda bubonisa ngokucacileyo ukuba i-crucible inokusondela okanye ifikelele ekupheleni kobomi bayo obuncedo. Ukucuthwa kodonga lwe-crucible kwi-crack igxininisa ngakumbi ukuba i-crucible ayinakukwazi ukumelana noxinzelelo olugqithisileyo, ibeka umngcipheko omkhulu kwinkqubo yoshishino ngokubanzi apho isetyenziswe khona.
Ukujongana nale miba kubalulekile ekuqinisekiseni ukuba iinkqubo zemizi-mveliso ezixhomekeke kuzoi-graphite silicon carbide crucible ukuqhubeka nokusebenza ngokukhuselekileyo nangempumelelo. Abaqhubi bemizi-mveliso kunye nabasebenzi bolondolozo kufuneka babeke iliso elibukhali imeko yei-graphite silicon carbide crucible kunye nokuthatha amanyathelo asebenzayo ukunciphisa umngcipheko wokungaphumeleli kwesakhiwo.
Ukuhlolwa rhoqo kunye nokugcinwa kweprotocol kufuneka kusekwe ukuze kubonwe iimpawu zokuqala zokunxitywa kwe-crucible kunye nomonakalo. Ukongezelela, iindlela ezifanelekileyo zokufudumeza kunye nokusetyenziswa kwezixhobo ezifanelekileyo zokuphatha (ezifana ne-crucible tongs) zibalulekile ukukhusela ukubunjwa kweentanda kunye nokuqinisekisa ixesha elide le-crucible kwindawo yoshishino.
Ukongezelela, ukuyila kunye nokusebenza kwesithando somlilo kufuneka kuhlolwe ngokucophelela ukuze kuncitshiswe uxinzelelo oluthe ngqo kwi-crucible kunye nokukhusela i-oxidation egqithisileyo, engakhokelela ekubunjweni kokuqhekeka. Ukuthatha amanyathelo okulawula uxinzelelo lwangaphakathi, ngakumbi xa ujongene nezinto ezandisa kakhulu xa zifudumala, kubalulekile ukukhusela i-crucible kumonakalo wesakhiwo.
Isishwankathelo, ubukho bokuqhekeka kwe-longitudinal kwii-graphite silicon carbide crucible ifuna ingqwalasela ekhawulezileyo kunye namanyathelo okulungisa ukuthintela ubungozi obunokubakho kunye nokuphazamiseka kwiinkqubo zamashishini. Ngokubeka phambili ukugcinwa rhoqo, iinkqubo ezifanelekileyo zokuphatha kunye nokwenza ngcono ukusebenza kweziko, amashishini anokukhusela ingqibelelo yawo.i-graphite silicon carbide crucible kunye nokugcina ukuthembeka kwemisebenzi yabo yokuvelisa kunye nemveliso.
