1. Txheej txheem cej luam ntawm graphite crucible rau melting txhuas
Puas yog koj tab tom nrhiav rau kev daws teeb meem thiab ruaj khov rau melting txhuas? IbGraphite crucible rau melting txhuasyog koj cov lus teb. Lub npe paub rau nws cov cua sov ua tau zoo thiab thermal conductivity, cov crucible yog siv dav hauv txhuas casting thiab hlau foundries. Nws tau tsim kom wrove kub thiab xa cov txiaj ntsig tau zoo, muaj txiaj ntsig zoo txhua zaus.
2. Cov yam ntxwv tseem ceeb
- Siab siab thermal conductivity: Graphite muaj cov cua sov zoo dua, uas txhais tau tias nrawm dua melting thiab lub zog txuag.
- Yam ruaj khov: Tsim siv iostatic nias thev naus laus zis, tus ntoo ci ntsa iab tau ua kom ntev thiab lub zog, ua rau nws ruaj khov.
- Corrosion Kuj: Cov graphite thiab silicon carbide muaj pes tsawg leeg ua rau nws tiv taus tshuaj corrosion, kom ntseeg tau lub purity ntawm molten aluminium.
- Cov Kub Kub Kuj: Nrog lub ntsiab lus melting saum toj no 1600 ° C, qhov Crucible no tuaj yeem ua rau ib puag ncig feem ntau xav tau.
3. Cov khoom siv thiab tsim qauv

Txoj kev no ua kom ntseeg tau tias tus ntoo khaub lig ntom ntom ntom ntom ntom ntom ntom ntom ntom. Qhov tshwm sim yog cov khoom lag luam uas tuaj yeem ua tau ntev los ntawm ntau cov voj voog ntawm qhov ntsuas kub siab.
4. Cov Khoom Txij Nkawm thiab Cov Lus Qhia Siv
- Preheating: Ib txwm preheat cov crucible maj mus rau 500 ° C ua ntej ua haujlwm puv ntoob. Qhov no pab zam kom tsis txhob thermal poob siab thiab ntev lub neej ntawm tus ntoo khaub zig.
- Ntxuav: Tom qab txhua qhov siv, nco ntsoov ntxuav tawm cov ntaub ntawv tseem ceeb. Siv cov txhuam muag muag lossis cov cua compressed los tiv thaiv kev puas tsuaj rau saum ntoo khaub lig.
- Chaw ntim khoom: Khaws cov crucible nyob rau hauv ib puag ncig qhuav kom tsis txhob muaj kev nqus dej noo, uas tuaj yeem ua rau cov khoom siv tsis muaj zog.
5. Cov Khoom Siv Khoom Muag
| Chaw ua uas tsis tau haus | Lub hom phiaj | Ntsuam cov ntaub ntawv |
|---|---|---|
| Kub tiv thaiv | ≥ 1630 ° C | ≥ 1635 ° C |
| Cov ntsiab lus carbon | ≥ 38% | ≥ 41.46% |
| Pom porosity | ≤ 35% | ≤ 32% |
| Lub qhov ntim ntawj ntom | ≥ 1.6g /M³ | ≥ 1.71g /M³ |
6. Cov lus nquag nug (FAQ)
Q1: Kuv puas tuaj yeem siv cov ntoo khaub lig no rau cov hlau lwm yam tshaj txhuas?
Yog lawm, dhau dhau txhuas, cov crucible no yog tseem haum rau cov hlau uas zoo li tooj liab, zinc, thiab nyiaj. Nws yog veratusile thiab ua haujlwm zoo rau ntau yam hlau.
Q2: Yuav ntev npaum li cas graphite crucable kawg?
Lub neej yog nyob ntawm qhov zaus ntawm kev siv thiab txij nkawm, tab sis nrog kev saib xyuas kom zoo, graphite crucible tuaj yeem nyob ntev txog 6-12 lub hlis.
Q3: Dab tsi yog txoj kev zoo tshaj plaws rau kev tswj hwm graphite?
Nco ntsoov tias nws tau ntxuav tom qab txhua qhov kev siv, zam kev hloov qhov kub tam sim no, thiab khaws cia hauv qhov chaw qhuav. Tsim kho kom tsim nyog tau txuas ntxiv nws lifespan.
