Refractory Raw Khoom

Dawb tabular alumina yog qhov sib xyaw ntawm kev xaiv nyob rau hauv unshaped thiab zoo li zoo li cov kev ua tau zoo refractories.

Dawb corundum yog ib yam khoom zoo heev - zoo refractory raw khoom nrog cov yam ntxwv ntawm siab hardness, siab zog, kub tsis kam thiab tshuaj stability. Nws muaj ntau yam kev siv thiab tuaj yeem ua

Brown corundum, dav siv nyob rau hauv lub teb ntawm refractory raw cov ntaub ntawv, yog ib tug siab - zoo quartz xuab zeb khoom nrog siab hardness, siab melting point, corrosion kuj thiab nplaim

Lub purity ntawm refractory calcined alumina hmoov yog siab li 99.99% lossis ntau dua. Vim nws cov kev ua tau zoo heev, nws yog dav siv nyob rau hauv lub teb ntawm refractory ntaub ntawv, xws li

refractory siab -alumina bauxite yog ib qho khoom siv zoo heev nrog cov cua kub tsis kam, compressive zog thiab tshuaj stability. Nws yog dav siv hauv steel, cement, iav, tshuaj thiab lwm yam kev lag

Magnesia yog ib qho ntawm cov khoom siv raw rau refractories. Kuj hu ua magnesia refractory raw cov ntaub ntawv, nws hais txog raw cov ntaub ntawv nrog MgO ua lub ntsiab tivthaiv thiab periclase raws

Magnesia (magnesite clinker) yog ib qho ntawm cov khoom tseem ceeb tshaj plaws rau cov khoom siv refractory. Nws yog siv los tsim ntau yam magnesia cib, magnesia-alumina cib, ramming cov ntaub ntawv,

High-kub calcined alumina hmoov yog ua los ntawm cov khoom siv txhuas hydroxide lossis muaj alumina ua raw khoom, thiab yog calcined ntawm qhov tsim nyog kub los tsim ib qho ruaj khov - hom alumina

Calcined bauxite yog ib qho siab - alumina (80--90%), cov ntxhia ua haujlwm ruaj khov uas ua los ntawm cov cua sov nyoos bauxite rau 1600--1800℃hauv cov kiln kom tshem tawm cov dej noo thiab

Nrog rau kev txhim kho txuas ntxiv mus rau kev ua tau zoo ntawm cov khoom siv refractory, qhov kev faib ua feem ntawm corundum siv hauv cov ntaub ntawv refractory tau nce siab dua. Corundum rau

Flint av nplaum yog sib xyaw ntawm ntau aluminosilicates. Cov khoom siv tshuaj lom neeg tseem ceeb yog ob lub oxides ntawm Al2O3 thiab SiO2, thiab cov impurities feem ntau yog oxides ntawm alkali,

Bauxite hauv kev lag luam refractory feem ntau yog hais txog bauxite nrog calcined Alumina ntau dua 48% thiab cov ntsiab lus ferrum tsawg.. Cov ntaub ntawv refractory xa mus rau inorganic non{0}}cov
