Graphite Crucible Rau Kub Melting

Graphite crucible rau kub melting yog ib qho cuab yeej tseem ceeb rau melting kub thiab lwm yam hlau muaj nuj nqis. Kev siv cov graphite crucible tsim nyog plays lub luag haujlwm tseem ceeb hauv qhov kawg tshwm sim. Graphite crucible tau dhau los ua qhov kev xaiv tseem ceeb hauv kev lag luam metallurgical vim nws qhov kub thiab txias tsis kam, corrosion kuj thiab ruaj khov tshuaj lom neeg. Niaj hnub no peb yuav piav qhia txog cov yam ntxwv thiab kev siv ntawm kub melting graphite crucible!
Cov yam ntxwv ntawm kub melting graphite crucible:
1. High thermal conductivity: Graphite crucibles muaj cov thermal conductivity siab, uas txhais tau tias lawv tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj kev puas tsuaj lossis deformed.
2. Chemically Inert: Graphite yog chemically inert khoom, uas txhais tau hais tias nws tsis hnov ​​​​mob nrog cov tshuaj feem ntau. Cov cuab yeej no ua rau nws zoo tagnrho rau melting heev reactive precious hlau xws li kub.
3. Tsawg thermal expansion: Graphite muaj thermal expansion tsawg, uas ua rau nws tiv taus thermal shock thiab tawg.
4. High Purity: Graphite crucibles muaj qib purity siab, uas txhais tau tias lawv tsis tshua muaj kab mob molten hlau.
5. Durable: Graphite crucibles yog qhov ruaj khov heev thiab tuaj yeem tiv taus qhov kub thiab txias.
Daim ntawv thov ntawm graphite crucible:
1. Kev cob qhia cov hniav nyiaj hniav kub: Graphite crucible feem ntau yog siv rau hauv cov hniav nyiaj hniav kub rhiav kom smelt kub, nyiaj, platinum thiab lwm yam hlau zoo nkauj. Lawv pab ua kom tiav cov txiaj ntsig zoo thiab ua tau zoo.
2. Laboratory thwmsim: Graphite crucibles yog siv nyob rau hauv lub chaw soj nstuam los ua ntau yam thwmsim, tshwj xeeb tshaj yog cov uas muaj xws li kub siab.
3. Metallurgical kev lag luam: Graphite crucibles yog siv nyob rau hauv metallurgical kev lag luam rau melting hlau xws li hlau, tooj dag thiab txhuas.
4. Kev lag luam iav: Graphite crucible yog dav siv hauv kev lag luam iav rau melting thiab shaping iav.
Hauv cov ntsiab lus:
Graphite crucible yog cov cuab yeej tseem ceeb rau melting kub thiab lwm yam hlau muaj nuj nqis. Lawv cov khoom tshwj xeeb xws li thermal conductivity, tshuaj inertness, tsis tshua muaj thermal expansion, siab purity thiab durability ua rau lawv zoo tagnrho rau cov ntawv thov. Los ntawm kev xaiv qhov loj me thiab hom graphite crucible, ob qho tib si goldsmiths thiab metallurgists tuaj yeem ua kom ntseeg tau zoo thiab ua haujlwm zoo.
