Magnesia-alumina Spinel

Magnesia-alumina spinel yog hais txog cov khoom siv hluavtaws spinel refractory raw khoom siv magnesium oxide thiab txhuas trioxide ua raw khoom. Cov khoom siv raw no tsis tshua pom muaj nyob hauv qhov xwm txheej, thiab magnesium-aluminium spinel siv hauv kev lag luam yog tag nrho cov khoom tsim tawm. Bauxite-based sintered magnesia-aluminium spinel siv cov khoom zoo alumina nrog cov ntsiab lus Al2O3 ntau dua 76% thiab zoo-zoo lub teeb-hlwb magnesia hmoov nrog cov ntsiab lus MgO ntau dua 95%. Tom qab ntau theem homogenization txheej txheem, nws yog rhuab mus rau 1800 degree nyob rau hauv ib tug ultra-siab kub qhov cub. Nws yog sintered ntawm qhov kub siab saum toj no.
Cov yam ntxwv ntawm alumina-magnesia spinel:
Bauxite-raws li sintered magnesia-alumina spinel yog ua los ntawm cov khoom siv zoo alumina nrog cov ntsiab lus Al2O3 ntau dua 76% thiab zoo-zoo lub teeb-hlwb magnesia hmoov nrog MgO cov ntsiab lus ntau dua 95%. Tom qab ntau theem homogenization txheej txheem, nws yog ua tiav ntawm ultra-siab kub Nws yog sintered ntawm kub siab tshaj 1800 degree nyob rau hauv lub qhov cub. Nws muaj lub zog ntim siab ntom ntom ntom ntom ntom, cov ntsiab lus ntxhia cov ntsiab lus, cov qauv zoo nkauj, qauv coj ua zoo thiab ruaj khov. Magnesia-aluminium spinel muaj corrosion kuj zoo, muaj zog corrosion thiab tev muaj peev xwm, zoo slag kuj, puas kuj, zoo thermal shock stability, kub tsis kam thiab lwm yam kev ua tau zoo yam ntxwv. Nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov khoom siv refractory xws li magnesia-alumina spinel cib, ladle lining bricks, thiab ladle castables siv nyob rau hauv high-temperature tsam ntawm cement rotary kilns. Magnesia-aluminium spinel yog dav siv hauv cov ntaub ntawv refractory, steel smelting, cement rotary kilns thiab iav industrial kilns.
Daim ntawv thov ntawm Aluminium Magnesium Spinel
Nws muaj qhov zoo corrosion kuj, abrasion kuj thiab zoo thermal shock stability. Nws txoj kev siv tseem ceeb: Ua ntej, nws tuaj yeem hloov tau magnesia-chromium xuab zeb los ua magnesium-alumina spinel cib siv rau hauv cov cement rotary kilns, uas tsis tsuas yog zam chromium cov pa phem, tab sis kuj muaj kev tiv thaiv zoo; thib ob, nws yog siv los ua ladle castables, uas zoo heev txhim kho cov hlau daim hlau. Kev tiv thaiv corrosion ntawm lub hauv ob sab phlu. Ua nws dav siv los ua cov ntaub ntawv refractory rau steelmaking. Kev npaj ntawm cov khoom zoo ua ntej-synthesized spinel muab cov ntaub ntawv tshiab rau kev tsim cov amorphous thiab zoo li cov ntaub ntawv zoo-purity refractory.
