Monga chida chofunikira paukadaulo wamakono wakuponya,silicon carbide cruciblepang'onopang'ono chakhala chidebe chomwe chimakondedwa kwambiri chosungunulira zitsulo zopanda chitsulo chifukwa chakuchita bwino komanso zinthu zapadera. Makamaka pokonza zitsulo zotentha kwambiri zimasungunuka, ma silicon carbide crucibles amawonetsa zabwino zambiri zaukadaulo. Nkhaniyi ifotokoza mwatsatanetsatane za magwiridwe antchito a silicon carbide crucibles, momwe angagwiritsire ntchito poponya, komanso momwe angaperekere mayankho ogwira mtima komanso odalirika kwamakampani amakono oponya.
1. Kodi silicon carbide crucible ndi chiyani?
Silicon carbide crucible ndi chidebe chotentha kwambiri chogwiritsa ntchito silicon carbide (SiC) ngati chida chachikulu. Amagwiritsidwa ntchito kwambiri posungunula ndi kukonza zitsulo zosiyanasiyana ndi ma aloyi. Silicon carbide ndi chinthu chopangidwa ndi kuuma kwambiri komanso kukana kutentha. Amagwiritsidwa ntchito kwambiri m'magawo apamwamba kwambiri monga ceramics, metallurgy, ndi semiconductors.
Chifukwa ma silicon carbide crucibles ali ndi zinthu zabwino kwambiri zakuthupi komanso zamankhwala monga kutenthetsa kwambiri, kutsika kwamafuta owonjezera, komanso kukana kwa dzimbiri, amawonetsa kukhazikika kosayerekezeka ndi kukhazikika pansi pa kutentha kwambiri komanso mikhalidwe yovuta kwambiri.
2. Ubwino waukadaulo wa silicon carbide crucible
1. Zabwino kwambiri kutentha kukana
Ma silicon carbide crucibles amakhala ndi kutentha kwambiri ndipo amatha kupirira kutentha kopitilira 1600 ° C. Izi zimawapangitsa kukhala abwino kusungunula zitsulo zotentha kwambiri monga mkuwa, aluminiyamu ndi faifi tambala. Poyerekeza ndi zitsulo zopangidwa ndi zipangizo zina, mphamvu za silicon carbide crucibles sizimachepa kwambiri pansi pa kutentha kwakukulu, kuonetsetsa kuti mawonekedwe ake azikhala okhazikika panthawi ya smelting.
Kukaniza kwapamwamba kwambiri kumeneku kumathandiza makampani kuti apewe ma crucibles kuti asapunduke kapena kusweka chifukwa cha kutentha kwambiri, potero kumapangitsa kuti ntchitoyo isapitirire komanso igwire bwino ntchito.
2. Wabwino matenthedwe madutsidwe
Chinthu chinanso chodziwika bwino cha silicon carbide ndi mphamvu yake yotentha kwambiri, yomwe imalola kusuntha kwachangu komanso ngakhale kutentha. Izi zikutanthauza kuti panthawi yosungunula, chitsulo chosungunula chimatha kufika kutentha kofunikira, kuchepetsa nthawi yosungunuka ndikuwongolera kupanga bwino.
Kutentha kwabwino kumeneku kumachepetsanso kutenthedwa kwachitsulo chosungunula, kumathandizira kukwaniritsa kuwongolera kutentha koyenera panthawi yoponya ndikuwonetsetsa kuti chitsulo chosungunula chimatenthedwa.
3. Coefficient yowonjezera yowonjezera kutentha
Coefficient of thermal expansion imatanthawuza momwe chinthu chimachulukira mu voliyumu chikatenthedwa. Silicon carbide ili ndi coefficient yotsika kwambiri pakukulitsa kutentha, zomwe zikutanthauza kuti imasintha pang'ono kukula ikatenthedwa. Choncho, ngakhale m'malo omwe ali ndi kusinthasintha kwakukulu kwa kutentha, silicon carbide crucible imatha kusunga mawonekedwe ake oyambirira ndikupewa ming'alu kapena kuwonongeka chifukwa cha kufalikira kapena kutsika.
Kuwotcha kwamafuta ochepa kumakhala koyenera kwambiri poponyera zinthu zomwe zimaphatikiza kutenthetsa pafupipafupi ndi kuziziritsa, zomwe zimakulitsa kwambiri moyo wautumiki wa crucible.
4. Kukana kwabwino kwa dzimbiri
Panthawi yosungunula, chitsulo chosungunula chimagwira ndi crucible, pang'onopang'ono kuwononga pamwamba pake. Komabe, zinthu za silicon carbide zimakhala ndi kukana kwa dzimbiri kwa mankhwala ndipo zimatha kukana kukokoloka kwa zakumwa zachitsulo, makamaka pochita ndi zitsulo zotakasuka kwambiri monga mkuwa ndi aluminiyamu.
Kukana bwino kwa dzimbiri kumangowonjezera moyo wautumiki wa crucible, komanso kumachepetsa kuipitsidwa koyipa komwe kumachitika chifukwa cha dzimbiri pamtunda, kuonetsetsa kuyera kwamadzi achitsulo ndikuwongolera mtundu wa chinthu chomaliza.
5. Mphamvu zamakina apamwamba
Ma silicon carbide crucibles amakhalabe ndi mphamvu zamakina apamwamba ngakhale kutentha kwambiri, zomwe zimapangitsa kuti asaphwanye kapena kupunduka. Makhalidwe apamwambawa amachititsa kuti crucible ikhale ndi mphamvu yachitsulo chosungunuka ndi kupanikizika kwa makina akunja, kusunga kukhazikika kwapangidwe panthawi yotentha kwambiri.
6. Kukhazikika kwabwino kwa kutentha kwa kutentha
Kukhazikika kwa kutentha kwa kutentha kumatanthauza kuthekera kwa chinthu kukana kusweka pamene kutentha kumasintha mofulumira. Ma silicon carbide crucibles amawonetsa kukhazikika kwamphamvu kwamafuta ndipo amatha kupirira kutentha kwachangu popanda kusweka. Izi ndizofunikira makamaka pakuponyera njira zomwe zimafuna kutentha ndi kuziziritsa pafupipafupi.
atatu. Kugwiritsa ntchito silicon carbide crucible
Chifukwa cha kukana kwake kutentha kwambiri, kutentha kwa kutentha, komanso kukana kwa dzimbiri, ma silicon carbide crucibles amagwiritsidwa ntchito kwambiri posungunula ndi kuponyera zitsulo, makamaka pakusungunula zitsulo zopanda chitsulo ndi aloyi. Zotsatirazi ndi zingapo zomwe zimagwiritsidwa ntchito nthawi zambiri:
Kuponyera mkuwa: Posungunula mkuwa,silicon carbide crucibles amatha kusunga kutentha kwa yunifolomu, kuchepetsa mapangidwe a zonyansa, ndi kupititsa patsogolo mbali zamkuwa.
Aluminiyamu ndi zitsulo zotayidwa zitsulo zosungunula: Aluminiyamu imakhudzidwa mosavuta ndi crucible panthawi yosungunuka, koma kukana kwa dzimbiri kwa silicon carbide kumateteza bwino crucible ku dzimbiri za aluminiyumu ndikuwonjezera moyo wake wautumiki.
Kusungunula kwina kotentha kwambiri: Silicon carbide crucible ndiyoyeneranso kusungunula zitsulo zotentha kwambiri monga zinki ndi faifi tambala, ndipo imatha kusinthika mwamphamvu.
Zinayi. Kugwiritsa ntchito ndi kukonza silicon carbide crucible
Kuti muwonjezere moyo wautumiki wa silicon carbide crucibles, kugwiritsa ntchito moyenera ndi kukonza ndikofunikira. Nazi malingaliro ena:
Preheat the crucible: Musanagwiritse ntchito koyamba kapena kugwiritsanso ntchito, tikulimbikitsidwa kuti pang'onopang'ono mutenthetse kutentha kwa crucible kuti muteteze kutentha kwadzidzidzi ndi kuphulika.
Pewani kutentha ndi kuziziritsa mwachangu: Ngakhale ma silicon carbide crucibles ali ndi kukhazikika kwamphamvu kwa kutentha, kusintha kwachangu kwambiri kumatha kuwononga crucible.
Kuyang'ana pafupipafupi: Mukamagwiritsa ntchito, yang'anani nthawi zonse pamwamba pa crucible kuti muwone ngati pali ming'alu kapena dzimbiri, ndikuthetsa zovuta zomwe zingachitike munthawi yake.
