I-Hydrostatic Silicon Carbide Crucible: I-Revolutionizing High Temperature Processing

Emkhakheni we-metallurgy, ukufuna izinsimbi eziqinile nezisebenzayo bekulokhu kuwukukhathazeka okuyinhloko. Uma ufuna i-crucible ekhethekile efanelekile izinqubo zokushisa okuphezulu, kei-hydrostatic silicon carbide crucibleskuyisinqumo sakho esingcono kakhulu. Ngezici zayo ezihlaba umxhwele, le Crucible iguqula imboni futhi iba yithuluzi elibalulekile kumabhizinisi emhlabeni jikelele.

I-Hydrostatic silicon carbide crucibles inenhlanganisela enhle kakhulu yezici ezizehlukanisa nezinsimbi zendabuko. Okokuqala, ukuqhutshwa kwayo okuphezulu kwe-thermal kutholakala ngokusebenzisa izinto ezifana ne-graphite, enciphisa izikhathi zokuncibilika. Lokhu kusiza amabhizinisi ukuthi onge isikhathi esibalulekile sokukhiqiza, okubavumela ukuthi bahlangabezane nezidingo zamakhasimende ngesikhathi esifanele.

Ngaphezu kwalokho, ama-crucibles anikeza ukushisa okungenakuqhathaniswa nomthelela wokumelana. Ukwakhiwa kwayo okuqinile kuqinisekisa ukuthi ingakwazi ukumelana nokushintshashintsha kwezinga lokushisa ngaphandle kokuqhekeka. Ezingeni eliphezulu lokushisa phakathi kuka-1200 no-1650 °C, le crucible ifakazele ukuqina kwayo futhi ihlale igcina ubuqotho bayo. Ngokumelana nokushisa okuhlaba umxhwele okunjalo, amabhizinisi angakwazi ukusunduza ngokuzethemba imingcele yezinqubo zawo.

Enye yezinzuzo eziyinhloko ze-hydrostatic silicon carbide crucibles ukumelana kwazo nokuhlaselwa yi-melt. Ukusabela kwamakhemikhali nezinto ezonakalisayo kuvame ukubangela ukulimala ezitsheni zendabuko, okuholela ekwenyukeni kwezindleko kanye nokuncipha kokusebenza kahle. Kodwa-ke, ukumelana nokugqwala okuhle kakhulu kwale crucible kuqinisekisa ukuphila kwayo isikhathi eside nokuthembeka, okuyenza ibe ukukhetha okubiza amabhizinisi esikhathini eside.

Ukuguquguquka kwe-hydrostatic silicon carbide crucibles kubenza bafanelekele izinqubo ezihlukahlukene zokushisa okuphezulu. Ukusuka ekuncibilikeni kwengxube yensimbi kuya ekukhiqizweni kwe-ceramic, i-crucible ifakazele ukubaluleka kwayo ezimbonini eziningi. Ngaphezu kwalokho, i-crucible's superior thermal conductivity kanye nokumelana nokugqwala kuqinisekisa imiphumela engaguquki nenembayo, okuvumela izinkampani ukuthi zithole ngempumelelo ukuphuma kwekhwalithi ephezulu.

Mayelana nezinzuzo, amabhizinisi asebenzisa lesi sihluthulelo sokusebenza okuphezulu abone ukukhiqiza okwandayo ngenxa yokuncipha kwezikhathi zokuncibilika. Ukumelana nokushisa okuthuthukisiwe kuqinisekisa isikhathi esincane sokuphumula kanye nezindleko zokulungisa zokusebenza okungenazihibe. Ngaphezu kwalokho, ukumelana nokuguguleka kuqinisekisa impilo yesevisi ye-crucible, ukonga izindleko ngokuhamba kwesikhathi.

I-Hydrostatic silicon carbide crucibles ngempela ingushintsho lomdlalo kumabhizinisi adinga izixazululo ezinokwethenjelwa zenqubo yokushisa okuphezulu. Inhlanganisela yayo ye-thermal conductivity ephezulu, ukumelana nokushisa, ukumelana nomthelela, nokumelana nokugqwala kuyenza ibe ukukhetha okuphezulu. Amabhizinisi asebenzisa le crucible azokhuphula umkhiqizo, anciphise isikhathi sokuphumula futhi angabizi kakhulu. Yamukela ikusasa lokucubungula okunokushisa okuphezulu nge-hydrostatic silicon carbide crucibles, ukuthatha inqubo yokukhiqiza ukusebenza kahle kanye nekhwalithi kuya kumazinga amasha.
