graphite crucible

Kufotokozera
graphite crucible, crucible zopangidwa ndi graphite zakuthupi.Anthu akhala akugwiritsa ntchito zida za graphite crucibles.Anthu oyambirira ankagwiritsa ntchito graphite zachilengedwe (flaky graphite ndi earthy graphite) ndi dongo, slag kapena mchenga kuti asakanize zopanda kanthu, ndipo njira zopangira mbiya zinkagwiritsidwa ntchito popanga ma graphite crucibles osungunula zitsulo (mkuwa , Iron, chitsulo, etc.).Graphite crucible ali mkulu mawotchi mphamvu, refractoriness, matenthedwe madutsidwe, akhoza kupirira angapo smelting ndipo akhoza kukana kukokoloka kwa mkulu kutentha njira.Graphite crucible akhoza kusungunuka malleable kuponyedwa chitsulo, kuponyedwa zitsulo, mkuwa aloyi, nthaka aloyi, mkuwa solder, etc. Ndi chitukuko cha mafakitale amakono, mafakitale zitsulo zosiyanasiyana ntchito ng'anjo magetsi kusungunula zitsulo zosiyanasiyana, kotero ntchito graphite crucibles ntchito graphite zachilengedwe monga chinthu chaletsedwa.Komabe, ambiri osungunula mafakitale ang'onoang'ono akupitiriza kugwiritsa ntchito mtundu uwu wa graphite crucible.
Chiyambireni kutulukira kwa graphite yochita kupanga chakumapeto kwa zaka za m’ma 1800, anthu apanga ma graphite ochita kupanga kukhala mphira za graphite.Kupanga ndi kupanga graphite yoyera kwambiri, yolimba kwambiri, magalasi a kaboni, ndi zina zambiri, ma graphite crucibles opangidwa ndi zinthu izi amakulitsa kuchuluka kwa ma graphite crucibles kuyenga zitsulo zamtengo wapatali monga golidi ndi siliva., Atomic mphamvu ya uranium smelting, semiconductor material silicon single crystal, germanium single crystal kupanga, ndikugwiritsidwa ntchito poyesa mankhwala osiyanasiyana.
Ma graphite crucibles amagawidwa kukhala ma graphite crucibles achilengedwe, ma graphite crucibles opangidwa ndi anthu, ma graphite crucibles apamwamba kwambiri, ma vitreous carbon crucibles, ndi zina zambiri malinga ndi zinthu zawo.Malinga ndi cholingacho, pali zitsulo zachitsulo, zitsulo zamkuwa, zopangira golide, ndi zowunikira.

Mawonekedwe
Mlingo waukadaulo wopanga ma graphite crucibles apakhomo wafika kapena kupitilira zitsulo zotumizidwa kunja.Zojambula zapamwamba zapakhomo za graphite zili ndi izi:
1. Kuchulukana kwakukulu kwa ma graphite crucibles kumapangitsa kuti ma crucibles azikhala ndi matenthedwe abwino kwambiri, ndipo matenthedwe ake amatenthetsa bwino kwambiri kuposa ma crucibles ena ochokera kunja.;graphite crucible Graphite crucible .
2. graphite crucible ili ndi glaze wapadera wosanjikiza ndi wandiweyani akamaumba zinthu, bwino kwambiri kukana dzimbiri mankhwala ndi kutalikitsa moyo utumiki wake.
3. Zigawo za graphite mu graphite crucible zonse zachilengedwe graphite ndi matenthedwe conductivity zabwino kwambiri.Pambuyo pa kutentha kwa graphite crucible, sayenera kuikidwa pa tebulo lozizira lachitsulo mwamsanga kuti lisawonongeke chifukwa cha kuzizira kofulumira.

Kusamalira
1. Nambala yeniyeni ya crucible ndi mphamvu ya mkuwa (kg)
2. Mtsuko wa graphite uyenera kusungidwa pamalo owuma kapena pamtunda wamatabwa ukasungidwa.
3. Gwirani mosamala ponyamula, ndipo ndikoletsedwa kugwa ndi kugwedezeka.
4. Musanagwiritse ntchito, iyenera kuphikidwa ndi zipangizo zowumitsa kapena ng'anjo, ndipo kutentha kumawonjezeka pang'onopang'ono mpaka 500 ° C.
5. Chophimbacho chiyenera kuikidwa pansi pa kamwa la ng'anjo kuti chivundikiro cha ng'anjo zisavale pakamwa kumtunda kwa crucible.
6. Zowonjezera zowonjezera ziyenera kutengera kuchuluka kwa kusungunuka kwa crucible.Osawonjezera zinthu zambiri ndikuletsa crucible kuti isakanikizidwe.
7. Kutuluka kwa ng'anjo ndi crucible clamp ziyenera kugwirizana ndi mawonekedwe a crucible.Mbali yapakati ya clamp iyenera kuteteza crucible kuti isawonongeke ndi mphamvu.
8. Mukatulutsa slag yosungunuka ndi coke pamakoma amkati ndi akunja a crucible, jambulani kuti muteteze kuwonongeka kwa crucible.
9. Mtunda woyenera uyenera kusungidwa pakati pa crucible ndi khoma la ng'anjo, ndipo crucible iyenera kuikidwa pakati pa ng'anjo.
10. Kugwiritsa ntchito moyenera zida zoyaka moto ndi zowonjezera zidzachepetsa moyo wautumiki wa crucible.
11. Pogwiritsa ntchito, kutembenuza crucible kamodzi pa sabata kungathe kutalikitsa moyo wautumiki wa crucible.
12. Pewani moto woyaka moto kuti usapondereze mwachindunji mbali ndi pansi pa chulu cha crucible.
