Qhuav:
Fused magnesia feem ntau yog tsim los ntawm magnesite 47% min los ntawm kev muab yaj hauv lub tshuab hluav taws xob arc. Fused magnesia cov khoom muaj cov purity siab, loj crystalline nplej, cov qauv cog lus, muaj zog slag tsis kam, zoo thermal poob siab ruaj khov, thiab yog cov khoom siv zoo heev. Cov khoom siv hluav taws xob kub kub tseem yog cov tseem ceeb ua cov khoom siv ua cov qib siab magnesia cib, magnesia-carbon cib thiab amorphous refractories.
Cov yam ntxwv tseem ceeb ntawm cov khoom siv fused magnesia muaj raws li nram no:
compact qauv, siab melting point (txog 2800 ℃), tshuaj lom neeg ruaj khov, siab compressive zog, muaj zog rwb thaiv tsev, yaig tsis kam thiab corrosion kuj. Nws yog cov khoom siv tseem ceeb rau metallurgy, lub tsev tsim khoom, teeb pom kev lag luam, cua sov hauv ob sab phlu thiab cov ntaub ntawv ntau, ntxiv rau steel, cement thiab iav. Iav, tsis muaj hlau ua kom sib txawv thiab lwm yam kev lag luam indispensable tseem ceeb refractories.
Kev siv lub ntsiab ntawm cov magnesia fused:
fused magnesia feem ntau tuaj yeem siv los ua cov chaw pab tiv thaiv xws li phom cov ntaub ntawv, cov ntaub ntawv phom, cov ntaub ntawv tshwj xeeb tsis xws li ntws steel qhov ncauj cib, magnesia cib, magnesia chrome cib, thiab lwm yam. induction qhov cub thiab hluav taws xob arc furnaces. Nws yog qhov zoo tagnrho cov khoom siv rau kev ua kom magnesia crucible, cub tawg thiab ntau yam kub tsho.
