Njengesixhobo esibalulekileyo kumashishini afana nokunyibilikisa isinyithi kunye nezinye izicelo ezinobushushu obuphezulu,iicrucibles zegraphiteidlala indima ebalulekileyo ekuqulatheni nasekufudumezeni iintsimbi ezahlukeneyo kunye neealloyi.Nangona kunjalo, ubomi babo benkonzo babulinganiselwe, nto leyo enokuba luncedo kwaye ibangele iindleko ezongezelelweyo kubasebenzisi.Kweli nqaku, siza kuphonononga ezinye iindlela zokwandisa ixesha lokuphilaiicrucibles zegraphitekunye nokwandisa ixesha elide.
Iintsimbi zegraphitezisetyenziselwa kakhulu ukunyibilika kunye neenkqubo zokuphosa, ngenxa ye-conductivity ebalaseleyo ye-thermal, ukuxhathisa ukubola, kunye neempawu eziphikisayo.Nangona kunjalo, ixesha elide lokuphila kwabo kuxhomekeke kwizinto ezininzi, ezifana nomgangatho wezinto eziluhlaza, iinkqubo zokuvelisa, iimeko zokusebenza kunye neenkqubo zokulondoloza.Ke ngoko, kubalulekile ukukhetha izikhonkwane ezikumgangatho ophezulu kubaboneleli abathembekileyo kwaye ulandele izikhokelo ezicetyiswayo zokusetyenziswa kunye nokhathalelo lwabo.
Omnye umba obalulekileyo ochaphazela ubomi bemibhobho yegraphite yinkqubo yokufudumeza kunye nokupholisa.Ukutshintsha ngokukhawuleza kweqondo lokushisa, okubizwa ngokuba yi-thermal shock, kunokukhokelela ekuqhekekeni, ukusabalalisa, okanye ukuguqulwa kwee-crucibles, ekugqibeleni ukunciphisa ixesha elide kunye nokusebenza kwabo.Ukuthintela le miba, kucetyiswa ukuba ngokuthe ngcembe kwaye ngokufanayo ufudumeze izikhephe ngaphambi kokuba ungeze isinyithi okanye i-alloys kwaye emva koko uzipholise ngokuthe ngcembe emva kokuba inkqubo igqityiwe.
Enye into ebalulekileyo ekufuneka iqwalaselwe luhlobo lwentsimbi okanye ialloy elungiswayo.Izinyithi ezithile, ezifana nentsimbi, i-nickel, kunye ne-cobalt, zinokuphendulwa ngegraphite kumaqondo obushushu aphezulu kwaye zenze i-carbides, ezinokukhawulezisa ukunxiba kunye nokukrazula kwee-crucibles.Ukuze ugweme oku, kuyacetyiswa ukuba kusetyenziswe iingubo zokukhusela okanye iilayini kwii-crucibles okanye ukhethe amabakala akhethekileyo egraphite achasene neempendulo ezinjalo.
Ngaphezu koko, ukugcinwa okufanelekileyo kunye nokucocwa kwee-crucibles nako kubalulekile ekwandiseni ubomi babo kunye nokuthintela ukungcoliseka kwesinyithi okanye i-alloys.Kunconywa ukukhupha, ukupholisa, kunye nokucoca ii-crucibles emva kokusetyenziswa ngalunye usebenzisa izixhobo ezifanelekileyo kunye neekhemikhali ukuphelisa nayiphi na intsalela okanye ukungcola.Ukugcinwa ngokufanelekileyo kwee-crucibles kwindawo eyomileyo nekhuselekileyo nayo ibalulekile ukukhusela umonakalo womzimba okanye ukufunxa ukufuma.
Ukushwankathela, ukwandisa ixesha lokuphila kwee-graphite crucibles kufuna ukunamathela kwizenzo ezichanekileyo kunye nezilumkiso.Oku kubandakanya ukukhetha ii-crucibles ezikumgangatho ophezulu, ukuziphatha ngononophelo, ukulawula ukufudumeza kunye nenkqubo yokupholisa, ukukhusela kwiintsimbi ezisebenzayo, nokuzigcina rhoqo.Ngokwenza njalo, abasebenzisi banokonga ixesha, imali, kunye nezixhobo ngelixa beqinisekisa ukusebenza okufanayo kunye nokuthembekileyo kwe-crucible.
