Koj nkees hloov pauvtus ntooThaum lub sij hawm yaj melting? Txheeb xyuas peb cov kev hloov pauvGraphite carbon crucibles! Tej notus ntooyog tsim nrog siab thermal colority cov ntaub ntawv thiab siab tshaj yog cov txheej txheem moulding poulding txheej txheem, nrog ntom thiab cov qauv sib dhos thiab kev kub ceev thiab maj nrawm. Qhov no txhais tau tias koj tus crucible tsis tsuas kav ntev dua, tab sis koj kuj txuag tau ntawm cov nqi zog vim nws lub peev xwm ua tau zoo.
Piv nrog rau cov av nplaum uas muaj qhov tseem ceeb ntawm cov tawv ntoo, peb cov pa roj carbon ntsaa, peb cov carbon graphbles tuaj yeem nce cov kev pabcuam lub neej ntawm cov khoom qub los ntawm 2-5 zaug. Yog lawm, hais kev sib ntsib kom nquag crucible hloov thaum cov txheej txheem thiab nyob zoo rau cov khoom lag luam siab dua thiab cov nqi txuag tau. Cov khoom siv xaiv thiab kev kub siab nias ua rau lawv ob leeg muaj zog thiab muaj peev xwm ntawm nrog kev kub siab txog li 1700°C, thaum tseem muaj kev tsis sib haum xeeb mus rau lub cev thiab tshuaj ntawm cov yaj.
Tsis yog peb tsuas yog peb cov av nplaum grucite crucite crucosles siab nyob rau hauv qhov ntom ntom, tab sis lawv cov khoom siv cov khoom siv tau yog tsim los tawm tsam cov kev phom sij thiab oxidation feem ntau tau ntsib thaum hlau smelting. Hais qhov zoo rau lo plias thiab nyob zoo rau lub tshuab nqus tsev ntxhua khaub ncaws, cov txheej txheem zoo dua. Kev Tshaj Tawm Kev Tawm Tsam Tawm Oxidation kuj tseem ua kom pom tseeb tias cov teeb tsa hauv Crucible yog kev tiv thaiv zoo, uastxhais tau tias tsis muaj pov tseg thiab khaws nyiaj ntxiv.
Ntxiv rau design Nrog kojqhov toob kas, peb graphite crucibles muaj cov txiaj ntsig ntxiv ntawm kev ua phooj ywg ib puag ncig. Nrog cov oxidation siab tiv taus thiab ua kom cua sov tsis yeem txo qis hluav taws xob poob, txuag cov khoom qias neeg thiab txo cov kuab paug pov tseg. Peb cov crucibles muaj yuav luag tsis muaj kev cuam tshuam impurities, uas tsis tsuas yog txuag cov hlau, tab sis kuj tiv thaiv ib puag ncig.
Hauv cov ntsiab lus, peb graphite carbon cruciles, cov graphite crucibles, dav dav grucitres thiab ntau yam ntawm cov txiaj ntsig los txhim kho koj cov txheej txheem melting. Lawv muaj zog thiab muaj kev tiv thaiv zoo rau lub cev thiab tshuaj lom neeg ntawm cov yaj. Lawv kuj tseem yog eco-phooj ywg, ua rau lawv zoo tag nrho rau cov neeg uas muaj nuj nqis heev. Xaiv peb Graphite carbon cruciles rau kev ua haujlwm siab, yig thiab kev daws teeb meem.
