Dawb Tabular Alumina Rau Refractory

Khoom Taw Qhia

Tabular alumina yog ib qho ntshiab sintered corundum uas yog hlawv tag thiab tsis ntxiv nrog rau tej additives xws li MgO thiab B2O3. Nws muaj cov qauv siv lead ua ntawm ntxhib thiab tsim tau zoo -Al2O3, thiab cov ntsiab lus ntawm Al2O3 yog siab dua 99 feem pua. Plate-zoo li siv lead ua qauv, me me pores thiab kaw pores, thiab lub porosity yog roughly sib npaug rau cov fused corundum, siab purity, zoo ntim stability, tsawg re-sintering shrinkage, thiab high-temperature kho ntawm refractory los yog castables siv rau ntau lawm. Muaj zoo thermal poob siab stability thiab khoov lub zog, tab sis tus nqi yog siab dua lwm yam alumina.

Dawb Tabular Alumina rau Refractory

Tabular alumina, tseem hu ua alpha alumina, yog ib qho ntshiab, sintered corundum uas yog hlawv tag thiab tsis ntxiv nrog rau tej additives xws li MgO thiab B2O3. Nws muaj cov qauv siv lead ua ntawm ntxhib thiab tsim tau zoo -Al2O3, thiab cov ntsiab lus ntawm Al2O3 yog siab dua 99 feem pua. Lub rooj zoo li cov qauv siv lead ua, cov pores me me, thiab cov pores kaw ua rau nws cov khoom ntxeem tau zoo nrog cov ntxhib sib npaug sib npaug rau fused corundum. Nws yog yam ntxwv los ntawm siab purity, zoo ntim stability, tsawg re-sintering shrinkage, thiab high-temperature kho ntawm refractory los yog castables siv rau ntau lawm. Nws kuj muaj qhov zoo thermal shock stability thiab khoov lub zog.
