Dawb Fused Alumina muaj xim dawb thiab me ntsis hardness thiab toughness piv nrog cov xim av. Cov cuab yeej sib tsoo ua los ntawm cov khoom siv no yog tsim rau kev sib tsoo zoo ntawm cov pa roj carbon steel, high-speed steel thiab stainless hlau, Abrasive hmoov ntawm finer grit loj, kuj siv tau rau precision casting thiab high-qib refractory.
Dawb Fused Alumina yog tsim los ntawm industrial alumina hmoov, uas yog smelted nyob rau hauv ib tug hluav taws xob arc rauv ntawm ib tug kub ntawm tshaj 2000 degree thiab txias thiab crystallized kom tau txais dawb Fused Alumina frit. Dawb Fused Alumina thiab industrial alumina hmoov kuj muaj alumina, yog li vim li cas peb thiaj li yuav tsum tau ua haujlwm ntxiv rau kev smelting?
Qhov no yog vim muaj ntau tus yam ntxwv zoo ntawm Dawb Fused Alumina los ntawm nws cov -Al2O3 muaju, thaum cov ntsiab lus ntawm alumina ntawm cov hmoov alumina tsuas yog kwv yees li 98%, uas tsis yog tsuas yog muaj lwm yam impurities, tab sis kuj muaj Al2O3 isomers, uas tuaj yeem txo qhov txo qis. ntau yam khoom ntawm corundum cov ntaub ntawv. Yog li ntawd, nws yog tsim nyog los tshem tawm impurities los ntawm melting, purify lub alumina cov ntsiab lus, thiab daim ntawv -Al2O3 crystals los ntawm re-crystallization.
