Kungani Usebenzisana Nathi?

Uma usikhetha, uthola okungaphezu komkhiqizo—uthola uzakwethu.

• Ubuchwepheshe: Amashumi eminyaka yesipiliyoni embonini yokusungula.
• Ukwenza ngokwezifiso: Izixazululo ezenzelwe ukuhlangabezana nezidingo zakho ezithile.
• Ukusekela: Kusukela ekukhethweni kuya ekufakweni, sinawe kuzo zonke izinyathelo zendlela.

I-Carbon Crucible amaqhawe angaqanjwanga wokulingisa insimbi. Eqinisweni, badlala indima ebalulekile ekusingatheni ezinye zezinselele zokuncibilika ezinzima kuma-foundries nasezindaweni ezinezinga lokushisa eliphezulu. Ubuwazi yini ukuthi lezi zinsimbi zikwazi ukumelana namazinga okushisa angaphezu kuka-1600°C? Akuyona into encane leyo! Ukuqina kwazo, kuhlanganiswe ne-thermal conductivity ehlukile, kuzenza zibaluleke kakhulu emhlabeni wensimbi.

Umgomo wethu kuzoba ukuba umphakeli oqanjiwe wamadivayisi edijithali nezokuxhumana ngobuchwepheshe obuphezulu ngokunikeza isakhiwo esinenzuzo eyengeziwe, ukukhiqiza okusezingeni lomhlaba, namakhono esevisi eCarbon Crucible, Inkampani yethu izoqhubeka nokunamathela “esimisweni sekhwalithi ephezulu, enedumela, umsebenzisi kuqala” ngenhliziyo yonke. Samukela ngemfudumalo abangani abavela kuzo zonke izizinda zokuphila ukuze babavakashele futhi banikeze isiqondiso, basebenzisane futhi bakhe ikusasa eliqhakazile!
I-Carbon Bonded Silicon Carbide Crucibles isetshenziswa kakhulu ezindaweni zokuncibilikisa nokuphonsa izinsimbi ezingeyona insimbi ehlukene njengethusi, i-aluminium, igolide, isiliva, umthofu, i-zinc nama-alloys. Ukusetshenziswa kwalawa ma-crucibles kubangela ikhwalithi engaguquki, impilo ende yesevisi, ukunciphisa kakhulu ukusetshenziswa kukaphethiloli kanye nokuqina kwabasebenzi. Ngaphezu kwalokho, kuthuthukisa ukusebenza kahle komsebenzi futhi inikeza izinzuzo ezinhle kakhulu zezomnotho.

Izinto zokwakha kanye Nokwakha
I-graphite crucibles yenziwe ngezinto eziningana:

• I-graphite (45-55%): Ingxenye ewumgogodla, ehlinzeka ngokudluliswa kokushisa okuhle kakhulu kanye nokuzinza kwe-thermal.
• I-silicon carbide, i-silica, nobumba: Lezi zinto zithuthukisa amandla omshini we-crucible kanye nokumelana nokugqwala, ikakhulukazi ezindaweni ezishisayo.
• I-clay binder: Iqinisekisa ukuhlangana okufanele kwezinto, inikeze i-crucible ukuma kwayo nobuqotho besakhiwo.

Usayizi wezinhlayiyana ze-graphite ezisetshenzisiwe nazo ziyahlukahluka kuye ngosayizi nenjongo ye-crucible. Isibonelo, ama-crucible amakhulu asebenzisa i-graphite e-coarser, kuyilapho ama-crucible amancane adinga i-graphite ecijile ngokunemba okungcono nokusebenza.

Izicelo ze-Graphite Crucible
I-graphite carbon crucibles isetshenziswa kabanzi emikhakheni ehlukene:

• Ukusakaza kwensimbi okungeyona i-ferrous: Kulungele izinsimbi ezifana nethusi, igolide, isiliva, nethusi ngenxa ye-coefficient yazo ephansi yokunwetshwa kokushisa.
• Amafurnace okungenisa: Kwezinye izimo, ama-crucibles aklanyelwe ukusebenza namaza omlilo athile ukuze kuthuthukiswe ukusebenza kahle kwamandla nokulawula izinga lokushisa.
• Ukucutshungulwa kwamakhemikhali: Ukuzinza kwawo kwamakhemikhali kuwenza afanelekele ukusetshenziswa ezindaweni ezichayeke ezintweni ezine-asidi noma ezine-alkaline.

Amathiphu Okugcina Okubalulekile
Ukwandisa isikhathi sokuphila se-graphite carbon crucible, ukunakekelwa okufanele nokugcinwa kubalulekile:

1. Ukupholisa: Qinisekisa ukuthi i-crucible iphola ngokuphelele ngaphambi kokuyigcina ukuze uvimbele ukushaqeka okushisayo.
2. Ukuhlanza: Njalo susa insimbi eyinsalela kanye nokuguquguquka ngemva kokusetshenziswa ngakunye ukuvimbela ukungcola.
3. Isitoreji: Gcina i-crucible endaweni eyomile, kude nemithombo yokushisa eqondile, ukugwema ukumuncwa komswakama, okungaholela ekulimaleni kwesakhiwo.
