Kanjani ukwenza ama-turcibles

Njengethuluzi elibalulekile kubuchwepheshe besimanje sokuphosa,I-Silicon Carbide Elenyukayokancane kancane ube yisitsha esikhethwayo sokushaya okungafanele kwensimbi ngenxa yokusebenza kwayo okuhle kanye nezinto ezibonakalayo ezihlukile. Ikakhulu uma kucutshungulwa kwensimbi ephezulu yokushisa kwensimbi, ama-silicon Carbide ama-errucibles abonisa uchungechunge lwezinzuzo ezibalulekile zobuchwepheshe. Le ndatshana izokwethula ngokuningiliziwe izici zokusebenza kwe-Silicon Carbide Carbides, isicelo sayo ezinhlelweni zokuphonsa, nokuthi ungazinikeza kanjani izixazululo ezisebenzayo nezithembekile zezinkampani zesimanje zokuphosa.

1. Yini i-silicon Carbide ebekiwe?
I-Silicon Carbide ecashile yisitsha esiphakeme sokushisa sisebenzisa i-silicon Carbide (SIC) njengezinto eziphambili ezingavuthiwe. Isetshenziselwa ikakhulukazi ukunyibilikisa nokucubungula izinsimbi ezahlukahlukene nama-alloys. I-Silicon Carbide iyinto eyenziwe ngento yokwenziwa ngobulukhuni obuphakeme kakhulu nokumelana nokushisa. Kusetshenziswa kabanzi kwizinkambu zobuchwepheshe obuphakeme njengama-ceramics, metallurgy, nama-semiconductors.

Ngenxa yokuthi ama-selicon carbide ama-rucibles anezakhiwo ezinhle kakhulu zomzimba nezamakhemikhali ezifana nokuvuselelwa okuphezulu okushisayo, ukumelana okuphezulu okukhohlisayo, kanye nokuqina kokugqwala, kukhombisa ukuqina okungekho emthethweni, ukuqina okungekho ngaphansi kokushisa okuphezulu kanye nezimo eziphakeme.

1. Ukumelana okuhle kakhulu kokushisa okuphezulu
I-Silicon Carbide Carbide Crucibles inokumelana nokushisa okuphezulu kakhulu futhi ingamelana namazinga okushisa adlula i-1600 ° C. Lokhu kubenza balungele ukuncibilikisa izinsimbi eziphakeme zokushisa njengethusi, i-aluminium ne-nickel. Uma kuqhathaniswa nama-tucibles okwenziwe kwezinye izinto, amandla e-Silicon Carbide Carbide akwehlisi kakhulu ngaphansi kwezimo zokushisa eziphakeme, aqinisekise ukuqina kwalo ngesikhathi senqubo yokunqwabanisa.

Lokhu kumelana okushisa okuphezulu kakhulu kusiza izinkampani ukuthi zigweme ama-tucIbles kusuka ekulimaleni noma ekuqhekekeni ngenxa yamazinga okushisa aphezulu, ngaleyo ndlela kuthuthukise ukukhiqizwa kokukhiqizwa nokusebenza kahle.

2. Ukusebenza okuhle kakhulu okushisayo
Esinye isici esiphawuleka se-Silicon Carbide Material ukuthuthuka okuphezulu okuphezulu okushisayo, okuvumela ukudluliselwa okusheshayo nokushisa. Lokhu kusho ukuthi ngesikhathi senqubo yokunqwabanisa, i-molten Metal ingafinyelela ngokushesha izinga lokushisa elidingekayo, kunciphisa isikhathi sokuncibilika kanye nokwenza ngcono ukusebenza kahle kokukhiqiza.

Lokhu kushisa okusebenzayo kunciphisa nokushisa ngokweqile kwensimbi encibilikisiwe, kusiza ukufeza ukulawulwa okunembile kokushisa ngesikhathi senqubo yokuphonsa kanye nokuqinisekisa ikhwalithi yokuphonsa okungaguquki.

I-coefficie yokwandiswa kwe-thermal ibhekisa ezingeni lokuthi impahla yanda ngevolumu lapho ifudumele. I-Silicon Carbide ine-coefficient ephansi kakhulu yokwanda okushisayo, okusho ukuthi kushintsha kancane ngosayizi lapho kufuthelwa. Ngakho-ke, ngisho nasendaweni enokuguquguquka okukhulu kwezinga lokushisa, i-Silicon Carbive ebethelwe ingalondolozwa ukwakheka kwayo kwasekuqaleni futhi igweme ukuqhekeka noma ukulimala ngenxa yokwanda noma ukukhiqizwa.

Ukunwetshwa okuphansi okushisayo kufanelekile ikakhulukazi izinqubo zokuphonsa ezibandakanya ukufudumeza okuvame ukufudumeza nemijikelezo epholile, ukunweba kakhulu impilo yenkonzo yokubaleka.

4. Ukumelana Nokuthuthuka Okuhle kakhulu
Ngesikhathi senqubo yokunqwabanisa, i-molan Metal iphendula ngokunembathelwa, kancane kancane iqeda indawo yayo. Kodwa-ke, impahla ye-silicon carbide inokumelana okuhle kakhulu kwamakhemikhali.

Ukumelana nokugqwala okuhle akugcini nje ngokunweba impilo yenkonzo ebekiwe, kepha futhi kunciphisa ukungcoliswa kokungcola okubangelwa ukugqwala endaweni ebekiwe, kuqinisekisa ubumsulwa boketshezi lwensimbi kanye nokwenza ngcono ikhwalithi yomkhiqizo wokugcina.

5. Amandla aphezulu wemishini
I-Silicon Carbide Carbide igcina amandla aphezulu emishini ngisho nasemazingeni okushisa aphezulu, abenze banciphise amathuba okuthi baphule noma bakhubazeke. Lesi sici esinamandla esinamandla sinika amandla ukuhlakanipha ukumelana nomthelela wengcindezi yensimbi ebilisiwe nokucindezelwa kwangaphandle kwemishini, ukugcina ukuqina kwesakhiwo ngesikhathi sokushaya okushisa kakhulu.

6. Ukuqina okuhle okushaqisayo
Ukuqina okushaqisayo kusho amandla okuqukethwe ukuze umelane nokuqhekeka lapho izinga lokushisa lishintsha ngokushesha. I-Silicon Carbide Carbide Ebonisa ukuqina okuvusa umkhondo okuhle kakhulu futhi uyakwazi ukubekezelela izinguquko zokushisa ezisheshayo ngaphandle kokuqhekeka. Lokhu kubaluleke kakhulu ezinqubweni zokuphonsa ezidinga ukufudumala okujwayelekile nokupholisa.

ezintathu. Ukusetshenziswa kwe-silicon Carbide eBrassible
Ngenxa yokumelana kwayo kokushisa okuphezulu okuvelele, ukuvumelanisa okushisayo, nokumelana nokugqwala, ama-silicon Carbide ama-Carbive asetshenziswa kabanzi ezinhlanganweni ezihlukile zokushaya insimbi nezinqubo zokuphonsa, ikakhulukazi ekunyisweni kwezinsimbi ezingezona ze-Ferrous kanye nama-alloys. Okulandelayo izimo zesicelo eziningana ezijwayelekile:

Ukuphonsa kwe-Copper: Lapho kuncenga ithusi,I-Silicon Carbide Elenyukayos ingagcina umfaniswano wokushisa oncibilikayo, wehlise ukwakheka kokungcola, futhi uthuthukise ikhwalithi yezingxenye zethusi.
I-Aluminium ne-Aluminium Alloy Smorelting: I-Aluminium iphendula kalula ngesikhathi sokubhema, kepha ukumelana nokugqwala kwe-silicon Carbide kuvikela ngempumelelo ukugcwala kwe-aluminium futhi kunwebe impilo yayo yenkonzo.
Okunye ukubhema okushisa okuphezulu: I-Silicon Carbide Eletheleleke nayo ilungele ukubhema izinsimbi eziphakeme zokushisa ezifana ne-zinc ne-nickel, futhi inokuvumelana okuqinile.

Ezine. Sebenzisa kanye nokulungiswa kwe-silicon Carbide eBrain
Ukwelula impilo yensiza ye-Silicon Carbide Carbide Carbibles, ukusetshenziswa okulungile nokunakekelwa kubalulekile. Nazi iziphakamiso:

Preheat the Earcicible: Ngaphambi kokusebenzisa kokuqala noma ukusebenzisa kabusha, kunconywa kancane kancane Preheat kancane ngokusobala kokushisa okusebenzayo ukuvikela ukufudumala okungazelelwe nokuqhuma.
Gwema ukufudumeza okusheshayo nokupholisa: Yize ama-Silicon Carbide Carbide anokuqina okuhle okushisayo, izinguquko zokushisa ezisheshayo kakhulu zisazolimaza i-ebekiwe.
Ukuhlolwa okujwayelekile: Ngesikhathi sokusebenzisa, hlola njalo indawo ebelekile yezimpawu zokuqhekeka noma ukugqwala, futhi uxazulule izinkinga ezingaba khona ngesikhathi esifanele.
