Graphite mbiya, mbiya zopangidwa ndi zinthu graphite. Anthu akhala akugwiritsa ntchito mtanda wopangidwa ndi graphite. Anthu oyambirira kugwiritsa ntchito graphite yachilengedwe (flaky graphite ndi earthy graphite) ndi dongo, slag kapena mchenga kusakanikirana, ndipo njira zopangira zoumba zidagwiritsidwa ntchito kupanga miyala ya graphite yosungunula zitsulo (mkuwa, Iron, chitsulo, ndi zina zambiri). Graphite mbiya ali mkulu mawotchi mphamvu, refractoriness, matenthedwe madutsidwe, chingathe kupirira smelting angapo ndipo akhoza kukana kukokoloka kwa kutentha njira. Graphite mbiya akhoza kusungunuka malleable kuponya chitsulo, chitsulo chosungunula, aloyi mkuwa, aloyi nthaka, solder zamkuwa, etc. Ndi chitukuko cha mafakitale ano, mafakitale osiyanasiyana zitsulo ntchito ng'anjo magetsi kuti asungunuke zitsulo zosiyanasiyana, kotero ntchito crucibles graphite ntchito graphite achilengedwe zakuthupi zaletsedwa. Komabe, ambiri osungunula mafakitale ang'onoang'ono akupitilizabe kugwiritsa ntchito mtundu wa graphite mbiya.
Chiyambire kubwera kwa graphite yokumba kumapeto kwa zaka za zana la 19, anthu asintha graphite yokumba kukhala mtanda wa graphite. Kukula ndi kupanga kwa graphite wokhala ndi zoyera kwambiri, graphite yamphamvu kwambiri, kapu yamagalasi, ndi zina zambiri, zopangira graphite zopangidwa ndi zinthuzi zimathandizira kugwiritsa ntchito ma graphite a graphite. Kuphatikiza pazitsulo zosungunuka, ma graphite a graphite amagwiritsidwanso ntchito kuyeretsa zitsulo zamtengo wapatali monga golidi ndi siliva. , Atomic energy uranium smelting, semiconductor material silicon single crystal, germanium single crystal yopanga, ndikugwiritsa ntchito pakusanthula kwamankhwala osiyanasiyana.
Mafotokozedwe a graphite amagawidwa m'magulu achilengedwe a graphite, zopangidwa ndi anthu zopangidwa ndi graphite, zopangira zoyera kwambiri za graphite, ma vitreous kaboni crucibles, ndi zina zotero malinga ndi zomwe ali nazo. Malinga ndi cholinga chake, pamakhala zopachika zachitsulo, zopachika mkuwa, zopachikika zagolide, ndi zophatikizira zowunikira.

Mawonekedwe
Mulingo waukadaulo wopanga ma graphite opangidwa ndi graphite wafika kapena wapitilira zopitilira kunja. Makhalidwe apamwamba a graphite apamwamba ali ndi izi:
1. Kuchuluka kwake kwa ma graphite opangidwa ndi graphite kumapangitsa kuti ma crucibles azikhala ndi matenthedwe abwino kwambiri, ndipo matenthedwe ake otenthawa ndiabwino kwambiri kuposa ma crucibles ena ochokera kunja. ; Graphite mbiya graphite mbiya.
2. graphite mbiya ali wapadera glaze wosanjikiza ndi wandiweyani zinthu akamaumba, amene bwino bwino kukana dzimbiri la mankhwala ndi kutalikitsa moyo wake utumiki.
3. The graphite zigawo za graphite mbiya zonse zachilengedwe graphite ndi matenthedwe madutsidwe wabwino kwambiri. Graphite mbiya usavutike mtima, sikuyenera kuyikidwa patebulo lozizira lazitsulo nthawi yomweyo kuti lisawonongeke chifukwa chozizira kwambiri.
Graphite crucible
Kukonza
1. Chiwerengero cha mbiya ndi mkuwa (kg)
2. Mbiya ya graphite iyenera kusungidwa pamalo ouma kapena pakhoma lamatabwa ikasungidwa.
3. Gwirani mosamala mukamanyamula, ndipo ndizoletsedwa kugwetsa ndi kugwedeza.
4. Musanagwiritse ntchito, imayenera kuphikidwa ndi zida zoyanika kapena ng'anjo, ndipo kutentha kumakulirakulira mpaka 500 ° C.
5. Chombocho chiyenera kuikidwa pansi pa mkamwa mwa ng'anjo kuti chophimba cha ng'anjo chisavalike pakamwa pamtunda.
6. Zowonjezera zowonjezera ziyenera kutengera kusungunuka kwa mbiya. Musawonjezere zinthu zochulukirapo ndikupewa mbiya kuti isapanikizike.
7. Kutuluka m'ng'anjo ndi chomata chophatikizika kuyenera kufanana ndi mawonekedwe a mbiya. Gawo lapakati la achepetsa liyenera kuteteza mbiya kuti isawonongeke ndi mphamvu.
8. Mukatulutsa slag yosungunuka ndi coke pamakoma amkati ndi akunja a mbiya, dinani kuti muteteze kuwonongeka kwa mbiya.
9. Mtunda woyenera uyenera kusungidwa pakati pa mbiya ndi khoma la ng'anjo, ndipo mbiya iyikidwe pakati pa ng'anjoyo.
10. Kugwiritsa ntchito moyenera zida zothandizira kuyaka ndi zowonjezera kumachepetsa moyo wautumiki wa mbiya.
11. Pakugwiritsa ntchito, kutembenuza mbiya kamodzi pa sabata kumatha kutalikitsa moyo wautumiki wa mbiya.
12. Pewani lawi lamoto lowononga kwambiri kuti lisapopera mbewu mwachindunji pambali ndi pamunsi pa mbiya.
