Alumina Magnesia Castable

1. Steel kev lag luam: Alumina magnesia castable Siv rau hauv ob sab phlu ntawm lub tshuab cua sov, converters, hluav taws xob rauv, nruam casting thiab lwm yam khoom siv, uas tuaj yeem tiv taus qhov yaig ntawm qhov kub thiab txias, molten hlau thiab slag.
2. Non-ferrous hlau smelting: siv rau hauv ob sab phlu, npib tsib xee, lead, zinc thiab lwm yam uas tsis yog-ferrous hlau smelting rauv los txhim kho cov refractory kev ua tau zoo thiab kev pab lub neej ntawm lub cub tawg.
3. Kev lag luam iav: Raws li cov khoom siv refractory rau furnaces, nws txhim kho lub neej kev pab cuam ntawm lub cub tawg thiab qhov zoo ntawm cov iav.
4. Ceramic kev lag luam: siv nyob rau hauv kiln rooj tog thiab lub cub tawg linings ntawm ceramic firing kilns los txhim kho qhov zoo thiab tso zis ntawm ceramic khoom.

Cov ntaub ntawv raw siv hauv alumina magnesia castables muab faib ua ob hom: ntuj thiab hluavtaws. Cov khoom ua los ntawm cov khoom siv raw feem ntau siv bauxite clinker ua cov khoom sib xyaw, magnesia hmoov thiab bauxite clinker hmoov raws li matrix, thiab iav dej feem ntau yog siv los ua tus neeg sawv cev. Cov ntsuas lub cev thiab tshuaj lom neeg ntawm cov castable no yog: Al2O3 10% ~ 70%, MgO 8% ~ 15%, Fe2O3 <3%, ntim ntom 2.45 ~ 2.65g / cm3, compressive zog 25 ~ 30MPa, ziab kab shrinkage 0.25%-0.35%. Kev khiav hauj lwm kub yog 1500 ~ 1700 degree. Thaum siv cov castables, Al2O3 reacts nrog MgO ntawm qhov kub thiab txias ({23}} degree) los tsim magnesia-aluminium spinel (MgO·Al2O3).

Refractory alumina magnesia castables ua los ntawm cov khoom siv hluavtaws muaj cov tshuaj purity siab dua thiab ua haujlwm zoo dua. Feem ntau ntawm cov castables no siv cov alumina los yog cov qib tshwj xeeb bauxite thiab lub teeb-hlwb magnesium oxide ua raw khoom, thiab yog hauv av, pelletized, thiab calcined. Magnesia-aluminium spinel yog synthesized ua ntej los ntawm lwm yam txheej txheem, thiab tom qab ntawd siv los ua raw khoom los ua aggregate thiab hmoov, yog li nws tseem hu ua spinel castable. Txhawm rau tswj hwm nws qhov kev ua tau zoo ntawm qhov kub thiab txias, qhov castable no feem ntau siv cov calcium aluminate cov cement ua cov ntawv khi ua kom qis-cement castables. Cov ntsuas lub cev thiab tshuaj lom neeg ntawm aluminium-magnesium casting cov ntaub ntawv ua los ntawm cov khoom siv hluavtaws yog: MgO5% ~ 7%, Al2O390% ~ 95%, SiO2<0.5%. The density is 3.0~3.2g/cm3, the porosity is 14%~16%, and the compressive strength is 20~35MPa. The load softening temperature is 1600~1650℃, and the drying line shrinkage is 0.01%~0.05%.
