Ezi crucibles azihlangabezi kuphela iimfuno ezingqongqo zokunyibilika kobushushu obuphezulu, kodwa zikwanazo amandla abalulekileyo kunye nokulungelelana kokusingqongileyo, okwenza zibe zixhobo eziphambili zokuphuhliswa kweshishini le-aluminium yanamhlanje.

Iinzuzo ezizodwa ze-silicon carbide graphite crucible
I-Silicon carbide graphite crucible yi-crucible refractory eyenziwe ngomxube we-silicon carbide kunye ne-graphite, esetyenziswe ngokukodwa kwinkqubo yokunyibilika kwe-aluminium kunye ne-alloys yayo. Ukuqulunqwa kwezinto ezizodwa kunika i-crucible iintlobo ezahlukeneyo zepropathi ezigqwesileyo:

I-thermal conductivity egqwesileyo: Zombini i-silicon carbide kunye negraphite zine-conductivity ephezulu ye-thermal, enokufikelela ngokukhawuleza kunye nokuhanjiswa kobushushu obufanayo, ukuphucula ukusebenza kakuhle kokunyibilikisa, ukunciphisa ixesha lokunyibilikisa, kunye nokunciphisa ukusetyenziswa kwamandla.

Ukumelana nobushushu obuphezulu be-oxidation: Indibaniselwano ye-silicon carbide kunye negraphite inika i-crucible egqwesileyo ukumelana ne-oxidation kumaqondo obushushu aphezulu, ikhusela ngokufanelekileyo i-oxidation yomhlaba kunye nokwandisa ubomi bayo benkonzo.

Amandla aphezulu omatshini: I-silicon carbide graphite crucible igcina amandla aphezulu omatshini nakwiqondo lokushisa eliphezulu, livumela ukuba likwazi ukumelana noxinzelelo lwe-thermal kunye nomatshini owenziwe ngexesha lokunyibilika kwe-aluminium, ngaloo ndlela inciphisa umngcipheko womonakalo.

Ukuxhathisa kwi-Chemical corrosion: I-silicon carbide kunye ne-graphite izinto zinokumelana kakuhle kweekhemikhali kwi-aluminiyam kunye ne-alloys yayo, ukwandisa ngakumbi ubomi benkonzo ye-crucible kunye nokugcina ukucoceka kwemveliso yokunyibilikisa.

Utshintsho lwetekhnoloji luqhuba ukwenziwa kwezinto
Ukuqhubela phambili kobuchwephesha bokwenziwa kwanamhlanje kuye kwaphucula ngokuqhubekayo inkqubo yokuvelisa i-silicon carbide graphite crucibles. Ngokomzekelo, ukuxuba izinto ezichanekileyo kunye neteknoloji ye-sintering ephezulu yenza ukuba abavelisi bavelise ama-crucibles anezakhiwo ezixineneyo kunye nokusebenza okuzinzile. Ukongeza, ukuqaliswa kweteknoloji yoshicilelo lwe-3D kwenza kube lula ukuyila ii-crucibles ezinokwakheka okuyinkimbinkimbi ukuhlangabezana neemfuno ezithile zeenkqubo ezahlukeneyo zokunyibilikisa i-aluminium.

Faka igalelo kukhuseleko lokusingqongileyo kunye nophuhliso oluzinzileyo
Ukongeza ekusebenzeni okuphezulu, i-silicon carbide graphite crucibles nayo inegalelo ngokusebenzayo ekukhuselweni kwendalo kunye nophuhliso oluzinzileyo. Ukuqhuba ukushisa okusebenzayo kunciphisa ukusetyenziswa kwamandla, ngelixa ukuqina kwe-crucible kunciphisa ukuphindaphinda kokutshintshwa, ngokunciphisa ukuveliswa kwenkunkuma yezoshishino. Abanye abavelisi bakwaphonononga ukusetyenziswa kwezinto ezisetyenzisiweyo ukuphinda bacuthe impembelelo yokusingqongileyo.

Amathemba emarike kunye nokusetyenziswa
Njengoko ishishini le-aluminium liqhubeka likhula, imfuno yezixhobo eziphezulu zokunyibilikisa iyanda. I-silicon carbide graphite crucibles iya ithandwa kakhulu yimarike ngokusebenza kwayo okugqwesileyo kunye neempawu zokukhusela okusingqongileyo. Nokuba kwiziseko ze-aluminiyam okanye iinkampani zokulungisa i-aluminium kwiimoto, i-aerospace kunye namanye amashishini, i-silicon carbide graphite crucibles ibe lukhetho oluthembekileyo lokuphucula ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso.

ukuququmbela
Ukuvela kwe-silicon carbide graphite crucible marks ukuba iteknoloji yokunyibilikisa i-aluminium ingene kwixesha elitsha. Njengomqambi kwizixhobo zokunyibilikisa i-aluminium, i-silicon carbide graphite crucibles ayiphuculi nje ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso, kodwa iphinda ibeke imigangatho yoshishino ekusebenzeni kwamandla kunye nokukhuselwa kwendalo. Siya kuqhubeka nokuzinikela kwi-R&D kunye nokuveliswa kwe-silicon carbide graphite crucibles ephezulu yokusebenza, ukubonelela abathengi ngezisombululo ezithembekileyo zokunyibilikisa, kunye nokukhuthaza uphuhliso oluzinzileyo lweshishini le-aluminium.
