Graphite carbon crucible

Cov graphite carbon crucibleyog ib lub thawv tshwj xeeb siv nyob rau hauv qhov chaw kub kub rau melting thiab casting hlau, ceramics, thiab lwm yam ntaub ntawv. Ua los ntawm graphite feem ntau, nws muaj qhov tshwj xeeb thermal conductivity, tshuaj inertness, thiab tsis kam rau thermal shock. Cov khoom no ua rau graphite crucibles zoo tagnrho rau ntau yam kev lag luam, suav nrog smelting non-ferrous hlau xws li tooj liab, tooj dag, thiab txhuas.

Crucible loj

Khoom siv thiab kev tsim kho
Graphite crucibles yog tsim los ntawm ntau yam ntaub ntawv:

• Graphite (45-55%): Cov ntsiab lus tseem ceeb, muab cov cua sov hloov pauv zoo thiab thermal stability.
• Silicon carbide, silica, thiab av nplaum: Cov ntaub ntawv no txhim khu lub crucible lub zog txhua yam thiab tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv huab cua kub ib puag ncig.
• Av nplaum binder: Ua kom muaj kev sib raug zoo ntawm cov ntaub ntawv, muab lub crucible nws cov duab thiab cov qauv kev ncaj ncees.

Qhov luaj li cas ntawm graphite siv kuj txawv nyob ntawm seb lub crucible qhov loj thiab lub hom phiaj. Piv txwv li, crucibles loj siv coarser graphite, thaum me crucibles yuav tsum finer graphite kom zoo dua precision thiab kev ua tau zoo.

Kev siv ntawm Graphite Crucible
Graphite carbon crucibles yog siv dav hauv ntau qhov chaw:

• Non-ferrous hlau casting: Zoo tagnrho rau cov hlau xws li tooj liab, kub, nyiaj, thiab tooj dag vim lawv tsis tshua muaj coefficient ntawm thermal expansion.
• Induction rauv: Qee zaum, Crucibles yog tsim los ua haujlwm nrog rau cov cua sov tshwj xeeb kom ua kom lub zog ua haujlwm zoo thiab tswj qhov kub thiab txias.
• Kev ua tshuaj lom neeg: Lawv cov tshuaj stability ua rau lawv haum rau siv nyob rau hauv ib puag ncig raug rau acidic los yog alkaline cov ntaub ntawv.

Cov Lus Qhia Tseem Ceeb
Txhawm rau ua kom lub neej ntev tshaj plaws ntawm graphite carbon crucible, kev saib xyuas kom zoo thiab khaws cia yog qhov tseem ceeb:

1. Txias: Xyuas kom lub crucible cools down tag nrho ua ntej cia kom tiv thaiv thermal shock.
2. Ntxuav: Ib txwm tshem tawm cov hlau seem thiab cov flux tom qab txhua qhov kev siv los tiv thaiv kev sib kis.
3. Cia: Khaws lub crucible nyob rau hauv ib qho chaw qhuav, deb ntawm qhov chaw tshav kub ncaj qha, kom tsis txhob muaj kev nqus dej noo, uas tuaj yeem ua rau cov txheej txheem degradation.

Cov lus nug nquag nug (FAQ)

1. Lub graphite crucible ntev npaum li cas?
   Lub neej ntev nws txawv nyob ntawm kev siv, tab sis nrog kev saib xyuas kom zoo, graphite crucibles tuaj yeem kav ntev rau kaum ob lub voj voog yaj, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas tsis yog-ferrous hlau casting.
2. graphite crucibles puas tuaj yeem siv rau txhua hom rauv?
   Thaum muaj ntau yam, cov khoom siv crucible yuav tsum sib haum rau hom rauv. Piv txwv li, crucibles rau induction furnaces yuav tsum tau tshwj xeeb hluav taws xob resistivity kom tsis txhob overheating.
3. Dab tsi yog qhov kub siab tshaj plaws ntawm graphite crucible tuaj yeem tiv taus?
   Feem ntau, graphite crucibles tuaj yeem tswj qhov kub ntawm 400 ° C txog 1700 ° C, nyob ntawm seb cov khoom muaj pes tsawg leeg thiab daim ntawv thov.
