Graphite Refractory Pwm

Graphite Refractory Moulds: Lub luag haujlwm tseem ceeb hauv High-Tub kub Industrial Materials

Hauv kev tsim khoom lag luam niaj hnub no, siab -purity graphite refractory pwm ua lub luag haujlwm tseem ceeb hauv cov txheej txheem txheej txheem tsis tseem ceeb hauv metallurgy, hluav taws xob, tshuaj, thiab lub zog tshiab. High-purity graphite feem ntau yog hais txog cov khoom siv graphite uas muaj cov ntsiab lus carbon ntau dua 99.99%. Nws tsis tsuas yog tau txais txiaj ntsig zoo ntawm cov khoom siv graphite nkaus xwb tab sis kuj tseem muaj cov khoom siv siab heev thiab lub zog siv tshuab los ntawm cov txheej txheem siab heev xws li isostatic nias lossis molding thiab siab -kub kev kho cua sov. Los ntawm cov khoom siv hluav taws xob me me mus rau kev nruam nruam hauv kev lag luam metallurgical hnyav, siab -purity graphite pwm, nrog rau lawv qhov kev ua tau zoo, tau dhau los ua qhov kev xaiv zoo tshaj plaws rau molding thiab kev ua haujlwm hauv high - qhov kub thiab txias.

Qhov tseem ceeb ntawm kev ua tau zoo ntawm high-purity graphite refractory pwm nyob rau hauv lawv qhov tsis sib xws siab siab -kub tsis kam. Piv rau cov khoom siv hlau zoo tib yam uas muag los yog deform ntawm qhov kub thiab txias, lub zog ntawm graphite pwm nyob rau hauv ib qho chaw inert hauv qab 2500℃txawm nce nrog qhov kub thiab txias, tsuas yog maj mam txo tom qab ntau tshaj 2500 degree. Tsis tas li ntawd, graphite nws tus kheej muaj qhov tsis tshua muaj coefficient ntawm thermal expansion thiab thermal shock kuj zoo heev, ua rau nws tuaj yeem tiv taus cov kev hloov pauv hauv cua sov thiab cua txias yam tsis muaj kev tawg. Cov yam ntxwv no ua rau nws tshwj xeeb tshaj yog nyob rau hauv cov iav kub dabtsi yog khoov, cemented carbide sintering, thiab lub tshuab nqus tsev kub qhov chaw, kom ntseeg tau qhov ruaj khov ntawm cov pwm nyob rau hauv qhov kub sib txawv.

Cov tshuaj zoo heev inertness thiab tus kheej -lubricating zog ntawm siab- purity graphite pwm ua rau lawv tsis tshua muaj kev cuam tshuam nrog feem ntau cov hlau molten ntawm qhov kub thiab txias thiab tiv taus acid thiab alkali corrosion. Qhov no ua rau lawv tshwj xeeb tshaj yog tsim los ua pwm rau nruam casting lossis siab casting. Piv txwv li, thaum siv graphite pwm rau hlau casting, lawv nto nws tus kheej -lubrication tsis tsuas yog zoo tiv thaiv castings los ntawm sticking rau pwm, tab sis kuj ho txhim kho cov nto tiav ntawm cov castings. Ntau cov castings tuaj yeem siv ncaj qha yam tsis muaj kev ua haujlwm ntxiv, txuag cov ntaub ntawv hlau thiab cov nqi ua tom qab.

Tsis tas li ntawd, kev ua haujlwm ntawm kev lag luam thiab kev ua tau zoo ntawm siab -purity graphite refractory pwm tau raug tshawb xyuas tag nrho hauv kev lag luam xws li photovoltaics, semiconductors, thiab metallurgy. Hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, nws yog siv los ua cov khoom siv hluav taws xob hauv cov khoom siv lead ua kev loj hlob thiab cov graphite substrate hauv cov txheej txheem epitaxial; nyob rau hauv kev lag luam photovoltaic, nws ua haujlwm ua pwm rau sintering polycrystalline silicon; thiab nyob rau hauv nruam casting, nws ua raws li ib tug crystallizer. High- purity graphite pwm tsis yog tsuas yog rov siv tau ntau zaus, tab sis kuj muaj cov nqi raw khoom qis dua piv rau lwm cov khoom siv hlau zoo. Los ntawm kev txhim kho cov khoom lag luam tawm los thiab kev tsim khoom txuas ntxiv, lawv ua lub luag haujlwm tseem ceeb hauv kev txo cov nqi tsim khoom tag nrho ntawm cov lag luam.
