I-Silicon carbide graphite crucible: umsunguli embonini yokuncibilikisa i-aluminium

Ngokuthuthuka okuqhubekayo kobuchwepheshe bokuncibilikisa i-aluminium,i-silicon carbide graphite cruciblekancane kancane uye waba umkhiqizo wenkanyezi embonini yokukhiqiza i-aluminium ngenxa yokusebenza kwayo okuhle kakhulu nokuthembeka. Lawa ma-crucibles awagcini nje ngokuhlangabezana nezidingo eziqinile zokuncibilikisa izinga lokushisa eliphezulu, kodwa futhi abe namandla abalulekile kanye nobungane bemvelo, okubenza babe yimishini ebalulekile yokuthuthukiswa kwemboni yesimanje ye-aluminium.

Izinzuzo eziyingqayizivele ze-silicon carbide graphite crucible
I-Silicon carbide graphite crucible iyi-crucible refractory eyenziwe ngengxube ye-silicon carbide ne-graphite, esetshenziswa ngokukhethekile kwinqubo yokuncibilikisa i-aluminium nama-alloys ayo. Ukwakheka kwezinto eziyingqayizivele kunikeza i-crucible izici ezihlukahlukene ezinhle kakhulu:

Ukusebenza kahle kakhulu kwe-thermal: Kokubili i-silicon carbide ne-graphite inokuhamba okuphezulu kwe-thermal, okungafinyelela ukudluliswa kokushisa okusheshayo nokufana okufanayo, ukuthuthukisa ukusebenza kahle kokuncibilika, ukunciphisa isikhathi sokuncibilika, nokunciphisa ukusetshenziswa kwamandla.

Ukumelana nokushisa okuphezulu kwe-oxidation: Inhlanganisela ye-silicon carbide ne-graphite inikeza ukumelana ne-oxidation ye-crucible emazingeni okushisa aphezulu, ivimbele ngempumelelo i-oxidation ebusweni futhi inwebe impilo yayo yesevisi.

Amandla aphakeme emishini: I-silicon carbide graphite crucible igcina amandla aphezulu emishini ngisho nasezingeni eliphezulu lokushisa, ivumela ukuthi imelane nokucindezeleka okushisayo nokwemishini okukhiqizwa ngesikhathi sokuncibilika kwe-aluminium, ngaleyo ndlela inciphisa ingozi yokulimala.

Ukumelana nokugqwala kwamakhemikhali: Izinto ze-silicon carbide kanye ne-graphite zinokugqwala okuhle kwamakhemikhali ku-aluminium nama-alloys ayo, okuqhubeka nokwandisa impilo yesevisi ye-crucible nokugcina ubumsulwa bomkhiqizo oncibilikayo.

Ukuqamba okusha kwezobuchwepheshe kuqhuba ukukhiqiza okubalulekile
Ukuthuthuka kobuchwepheshe besimanje bokukhiqiza kuye kwathuthukisa ngokuqhubekayo inqubo yokukhiqiza i-silicon carbide graphite crucibles. Isibonelo, ukuxuba okunembile kwezinto ezibonakalayo kanye nobuchwepheshe be-sintering obuthuthukisiwe kwenza abakhiqizi bakwazi ukukhiqiza ama-crucible anezakhiwo eziminyene nokusebenza okuzinzile. Ukwengeza, ukwethulwa kobuchwepheshe bokuphrinta be-3D kwenza kube nokwenzeka ukuklama iziphambano ezinomumo oyinkimbinkimbi ukuze zihlangabezane nezidingo ezithile zezinqubo ezihlukahlukene zokuncibilikisa i-aluminium.

Ukubamba iqhaza ekuvikelweni kwemvelo kanye nentuthuko esimeme
Ngaphezu kokusebenza okuphezulu, ama-silicon carbide graphite crucibles nawo afaka isandla ekuvikelweni kwemvelo nasekuthuthukisweni okusimeme. Ukwenziwa kokushisa okuphumelelayo kunciphisa ukusetshenziswa kwamandla, kuyilapho ukuqina kwe-crucible kunciphisa imvamisa yokushintshwa, ngaleyo ndlela kunciphisa ukukhiqizwa kwemfucuza yezimboni. Abanye abakhiqizi bahlola nokusetshenziswa kwezinto ezigaywe kabusha ukuze baqhubeke nokunciphisa umthelela wendawo.

Amathemba emakethe kanye nezicelo
Njengoba imboni ye-aluminium iqhubeka nokuthuthuka, isidingo semishini yokuncibilikisa esebenza kahle kakhulu siyakhula. I-silicon carbide graphite crucibles iya ngokuya ithandwa yimakethe ngokusebenza kwayo okuhle kakhulu nezici zokuvikela imvelo. Kungakhathaliseki ukuthi kusezimbonini ze-aluminium noma ezinkampanini zokucubungula i-aluminium ezimbonini zezimoto, i-aerospace nezinye izimboni, ama-silicon carbide graphite crucibles abe yisinqumo esithembekile sokuthuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo.

Ekuphetheni
Ukuvela kwezimpawu ze-silicon carbide graphite crucible ubuchwepheshe bokuncibilikisa i-aluminium bungene enkathini entsha. Njengomsunguli wemishini yokuncibilikisa i-aluminium, i-silicon carbide graphite crucibles ayithuthukisi nje kuphela ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo, kodwa futhi isetha izilinganiso zemboni ekusebenzeni kahle kwamandla nokuvikelwa kwemvelo. Sizoqhubeka nokuzinikela ku-R&D kanye nokukhiqizwa kwezinsimbi ze-silicon carbide graphite crucibles ezisebenza kahle kakhulu, sinikeze amakhasimende izixazululo ezinokwethenjelwa zokuncibilikisa, futhi sikhuthaze intuthuko esimeme yemboni ye-aluminium.
