Graphite carbon Crucible

Cov graphite carbon crucibleyog cov thawv tshwj xeeb siv hauv qhov kev kub-ib puag ncig rau melting thiab casting hlau, ceramics, thiab lwm yam ntaub ntawv. Ua tshwj xeeb los ntawm graphite, nws muaj kev tshwj xeeb thermal conductivity, tshuaj lom neeg inertness, thiab kuj mus rau bermal poob siab. Cov khoom no ua rau cov txheej txheem crucibles zoo tagnrho rau ntau cov txheej txheem muaj kev siv, suav nrog smelting tsis-ferrous hlau zoo li tooj liab, tooj dag, thiab txhuas.

Crucible loj

Cov ntaub ntawv thiab kev tsim kho
Graphite crucles muaj ntau yam khoom:

• Graphite (45-55%): Cov ntsiab lus tseem ceeb, muab cov cua sov hloov pauv thiab ua kom ruaj khov.
• Silicon Carbide, Silica, Thiab Av: Cov ntaub ntawv no txhim kho cov crucible ntawm cov tshuab hluav taws xob muaj zog thiab tiv taus rau corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig kub heev.
• Av binder: Xyuas kom loj cohesion ntawm cov ntaub ntawv, muab nws cov kab ntoo thiab cov qauv txheej txheem kev ntseeg.

Lub particle loj ntawm graphite hloov kuj txawv nyob ntawm tus ntoo khaub lig loj thiab lub hom phiaj. Piv txwv li, loj crucailes siv coarser graphite, thaum me dua crucibles yuav tsum tau finer graphite rau kev ntsuas zoo dua thiab ua tau zoo.

Cov ntawv thov ntawm graphite crucible
Graphite carbon crucibles tau siv dav thoob cov yeeb yam:

• Cov Hlau Tsis-Ferrous Hlau Casting: Qhov zoo tagnrho rau cov hlau zoo li tooj liab, kub, nyiaj, thiab tooj daj vim lawv cov coefficient ntawm thermal expansion.
• Induction Rauv: Hauv qee kis, crucibles yog tsim los ua haujlwm nrog cov cua sov tshwj xeeb los tswj hwm lub zog kom zoo thiab ntsuas kub.
• Kev Lag Luam: Lawv cov tshuaj ruaj khov ua rau lawv haum rau kev siv nyob rau hauv cov chaw ib puag ncig raug rau acidic lossis alkaline cov ntaub ntawv.

CRUCIA LUB TSWV YIM
Txhawm rau kom ua tiav ntawm lub neej ntawm graphite carbon crucible, kev tu kom zoo thiab chaw khaws khoom yog qhov tseem ceeb:

1. Cua txias: Ua kom cov ntoo ci ntoo txias txias cia kom tag ua ntej cia kom tiv thaiv kev poob siab.
2. Ntxuav: Nco ntsoov tshem cov ntawv sau tseg thiab flux tom qab txhua qhov kev siv los tiv thaiv kev sib kis.
3. Chaw ntim khoom: Muab cov ntoo khaub zig muag ntoo qhuav, kom tsis txhob muaj cov cua kub ncaj qha, kom tsis txhob muaj kev nqus cov cua sov, uas tuaj yeem ua rau cov qauv teeb meem.

Cov Lus Nquag Nug (FAQ)

1. Ntev li cas graphite crucible zaum kawg?
   Lub neej sib txawv nyob ntawm kev siv tau nyob ntawm kev siv, tab sis nrog kev tu kom raug, tshwj xeeb yuav kav ntev mezens ntawm cov hlau tsis muaj zog, tshwj xeeb hauv cov hlau tsis-ferrous hlau casting cov ntawv thov.
2. Yuav siv cov crucibles tuaj yeem siv nyob rau hauv txhua qhov cub hluav taws xob?
   Thaum lub sij hawm veratile, cov khoom crucible yuav tsum phim lub cub tawg. Piv txwv li, crucibles rau induction rauv xav tau cov hluav taws xob tiv thaiv kom tsis txhob overheating.
3. Dab tsi yog qhov siab tshaj plaws kub ntawm graphite crucible tuaj yeem tiv taus?
   Feem ntau, graphite crucles tuaj yeem lis kub kub los ntawm 400 ° C rau 1700 ° C, nyob ntawm cov ntaub ntawv muaj pes tsawg leeg thiab daim ntawv thov.
