Iresiphi ye-graphite aillicon Carbide Carbide Carribles: Ukhiye ku-Step-Performance Metallurgy

Emhlabeni we-metallurgy kanye nesayensi yezinto zokwakha,okubalekaiyithuluzi elibalulekile lokuncibilika nangokuphonsa izinsimbi. Phakathi kwezinhlobo ezahlukahlukene ze-rucibles, ama-graphiton aillicon Carbide (SIC) amabhulukwe avela ngezakhiwo zazo ezihlukile, njengokuphamba okuphezulu okushisayo, ukuqina okuphezulu okuvelayo okuphezulu, kanye nokuqina okuphezulu kwamakhemikhali. Kulesi sihloko, sizokwelulwa kwiresiphi ye-graphite sic tucibles futhi sihlole ukuthi ukwakheka kwazo kunomthelela kanjani ekusebenzeni kwawo okuphawuleka ezihlolweni zokushisa okuphezulu.

Izithako eziyisisekelo

Izakhi eziyinhloko ze-graphite sic ama-scrucibles yi-flake graphite kanye ne-silicon carbide. I-flake graphite, imvamisa eyakha ama-40% -50% we-ebethelwe, ihlinzeka ngokusebenza okuhle kakhulu okushisayo kanye nokukhululeka, okusiza ekukhululweni okulula kwensimbi yensimbi. I-Silicon Carbide, okwenza i-20% -50% yale nto ebekiwe, inesibopho sokumelana nokungamelana ne-thermal okushisayo okuthe xaxa kanye nokuqina kwamakhemikhali emazingeni okushisa aphakeme.

Izingxenye ezingeziwe zokusebenza okuthuthukile

Ukuqhubeka nokwenza ngcono ukusebenza okushisa okuphezulu kanye nokuqina kwamakhemikhali kwezinto ezibaleka, ezengeziwe zengezwe kuresiphi:

1. I-Elemental Silicon powder (4% -10%): Ithuthukisa amandla aphezulu okushisa kanye nokumelana nokuvinjelwa kwe-oxidation kwe-ebekiwe.
2. I-Boron Carbide Powder (1% -5%): yandisa ukuqina kwamakhemikhali kanye nokumelana nezinsimbi ezilonakalisayo.
3. UClay (5% -15%): Izenzo njenge-binder futhi ithuthukisa amandla omshini kanye nokuqina okungekho emthethweni.
4. I-Thermosetting Binder (5% -10%): Isiza ekubopheni zonke izakhi ndawonye ukwakha isakhiwo esibumbana.

Ifomula eliphakeme kakhulu

Ngezicelo ezifuna ukusebenza okuphezulu kakhulu, kuqashwa ifomula ebekiwe ye-graphite yefomula ebekiwe. Le formula iqukethe izinhlayiya ezingama-98% we-graphic, 2% calcium oxide, 1% zirconium oxide, 1% i-sodic acid, 1% sodium silicate, no-1% we-aluminium silincate. Lezi zithako ezengeziwe zinikeza ukumelana okungenakuqhathaniswa nokushisa okuphezulu nasezindaweni ezinolaka kwamakhemikhali.

Inqubo Yokukhiqiza

Ukulungiswa kwe-graphite scrucibles ama-scric kubandakanya inqubo yokucophelela. Ekuqaleni, i-flake graphite kanye ne-silicon Carbide kuxutshwe kahle. Ngemuva kwalokho, i-aillicon kafulani ye-alemental, i-boron carbide powder, ubumba, kanye ne-thermosetting binder yengezwe engxube. Inhlanganisela icindezelwa ngesimo isebenzisa umshini wokucindezela obandayo. Ekugcineni, ama-Crucibles abunjiwe afakwe esithandweni sokushisa okuphezulu ukuze athuthukise amandla abo okusebenza kanye nokuqina okushisayo.

Izicelo nezinzuzo

Ama-graphite sic ama-stucic asetshenziswa kabanzi embonini ye-metallurgical ukuze ancibilikise futhi ancibilikise izinsimbi ezifana nensimbi, insimbi, ithusi kanye ne-aluminium. Ukusebenza kwabo okuphezulu okuphezulu kuqinisekisa ukufudumala okufanayo futhi kunciphise ukusetshenziswa kwamandla. Ukumelana nokushaqeka okuphezulu okushisayo kunciphisa ubungozi bokuqhekeka ngesikhathi sokushintsha okusheshayo kwezinga lokushisa, kanti ukuqina kwabo kwamakhemikhali kuqinisekisa ubumsulwa bensimbi ebilisiwe.

Ekuphetheni, iresiphi ye-Graphic Carbide Carbide iyinxuseli elungiselelwe kahle enikezela ngemali esele yokuvuselelwa okushisayo, ukumelana okushisayo, kanye nokuqina kwamakhemikhali. Lokhu kuhlanganiswa kubenza babaluleke kakhulu emkhakheni we-metallurgy, lapho bedlala khona indima ebalulekile ekunciphiseni okusebenzayo nokuthembekile okuncibilikayo nokukhonkotha kwezinsimbi.

Ngokuqonda izingxenye nezinqubo zokukhiqiza ze-Graphite Sic Crucibles, izimboni zingenza izinqumo ezinolwazi ngezinhlelo zazo ezithile, ziqinisekisa ukusebenza kahle kanye nokuphila isikhathi eside kwazo ezinyaweni zazo. Njengobuchwepheshe buthuthuka, izithuthukisi ezengeziwe kumasu wokupheka kanye namasu okukhiqiza ama-graphite sic ama-stucic ama-stucible alindelwe, aqhamukele indlela yezinqubo ezisebenza kahle futhi ezizinzile zensimbi.
