Qhov blog no tsom mus rau delve rau hauv cov ncauj lus no, muab kev nkag siab zoo ntawm seb graphite crucibles tuaj yeem siv rau lub hom phiaj no.
Nkag siab Graphite Crucibles
Graphite crucibles muaj npe nrov rau lawv qhov tshwj xeeb thermal conductivity, siab melting point, thiab tshuaj stability. Cov khoom no ua rau lawv muaj kev xaiv nrov hauv ntau hom kev lag luam, tshwj xeeb tshaj yog hauv cov hlau smelting. Peb Foundry Graphite Crucible yog tsim los tiv thaiv huab cua kub thiab hnyav tshuaj lom neeg ib puag ncig, kom ntseeg tau tias kev ua tau zoo hauv kev xav tau.
Lub siab thermal conductivity ntawm graphite tso cai rau kev hloov hluav taws xob zoo, ua kom cov hlau melting sai thiab lwm yam ntaub ntawv. Qhov no tsis yog tsuas yog txo cov kev siv hluav taws xob xwb tab sis kuj nce kev tsim khoom. Tsis tas li ntawd, graphite crucibles muaj cov coefficient tsawg ntawm thermal expansion, uas txhais tau hais tias lawv tuaj yeem tiv taus qhov kub thiab txias hloov tsis tau tawg lossis tawg. Cov cuab yeej no yog qhov tseem ceeb hauv kev siv cov ntaub ntawv uas tau yaj thiab txias dua.
Cov khoom siv refractory: lawv yog dab tsi?
Cov khoom siv refractory yog cov khoom uas tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj qhov cuam tshuam loj lossis hloov tshuaj lom neeg. Lawv feem ntau siv hauv kev lag luam xws li steelmaking, iav manufacturing, thiab ceramics ntau lawm. Piv txwv ntawm cov ntaub ntawv refractory muaj xws li alumina, silica, magnesia, thiab zirconia. Cov ntaub ntawv no muaj cov ntsiab lus melting uas muaj peev xwm tshaj 1,500℃(2,732℃F), ua rau lawv nyuaj rau yaj siv cov txheej txheem.
Puas yog Graphite Crucibles Melt Refractory Materials?
Cov lus teb yog yog, tab sis nrog qee qhov kev xav. Graphite crucibles tuaj yeem siv los yaj qee cov ntaub ntawv refractory, nyob ntawm lawv cov tshuaj muaj pes tsawg leeg thiab cov ntsiab lus melting. Graphite muaj qhov siab melting point ntawm kwv yees li 3,652℃(6,606℃F), uas txhais tau hais tias nws tuaj yeem tiv taus qhov kub thiab txias uas yuav tsum tau yaj ntau cov ntaub ntawv refractory.
Txawm li cas los xij, tsis yog txhua yam khoom siv refractory yog sib xws nrog graphite crucibles. Qee cov ntaub ntawv refractory, xws li cov uas muaj cov hlau reactive los yog cov tebchaw, tuaj yeem hnov mob nrog graphite ntawm qhov kub thiab txias, ua rau lub crucible degrade los yog ua tsis tiav. Piv txwv li, cov ntaub ntawv uas muaj cov pa oxygen los yog sulfur tuaj yeem ua rau cov graphite los ua cov pa roj carbon monoxide lossis carbon dioxide, uas tuaj yeem ua rau cov qauv crucible tsis muaj zog.
Txhawm rau txiav txim siab seb lub graphite crucible puas tsim nyog rau melting ib qho khoom siv refractory, nws yog ib qho tseem ceeb uas yuav tau xav txog cov hauv qab no:
Tshuaj Compatibility: Xyuas kom meej tias cov khoom siv refractory tsis hnov mob nrog graphite ntawm lub melting kub. Tham nrog ib tus kws tshaj lij cov ntaub ntawv lossis ua cov kev xeem sib raug ua ntej siv graphite crucible.
Melting Point: Lub ntsiab lus melting ntawm cov khoom siv refractory yuav tsum nyob rau hauv qhov kub thiab txias uas cov graphite crucible tuaj yeem tiv taus. Tshaj qhov kub ntawm lub crucible txwv yuav ua rau nws deform los yog tawg.
Cov xwm txheej ua haujlwm: Xav txog cov kev khiav hauj lwm, xws li cov cua sov, tus nqi cua txias, thiab cua. Kev kub ceev los yog cua txias tuaj yeem ua rau thermal stress, uas tuaj yeem ua rau tawg lossis tawg ntawm crucible. Tsis tas li ntawd, muaj cov roj reactive los yog cov khoom paug hauv cov huab cua tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub crucible.
Qhov zoo ntawm kev siv Graphite Crucibles rau Melting Refractory Materials
Txawm hais tias cov kev xav tau hais los saum no, muaj ntau qhov zoo rau kev siv graphite crucibles rau melting refractory cov ntaub ntawv:
Kub Kub Resistance: Graphite crucibles tuaj yeem tiv taus qhov kub thiab txias uas yuav tsum tau yaj ntau cov ntaub ntawv refractory, ua kom cov txheej txheem melting muaj txiaj ntsig thiab txhim khu kev qha.
