Kugawikana ndi makhalidwe onse a njerwa zapamwamba za alumina

The high-alumina refractory ikhoza kugawidwa molingana ndi mlingo wa khalidwe, womwe ukhoza kugawidwa pafupifupi m’magulu anayi: pali njerwa zapamwamba za alumini, zachiwiri, zachiwiri za alumina, njerwa zachitatu za alumini ndi zapadera. – Njerwa zapamwamba za aluminiyamu. Pankhani ya lingaliro lokhazikika lamakampani, zizindikiro zamakina Omwe ali ndi aluminiyumu ≥55% amakhala njerwa zapamwamba zamtundu wachitatu, omwe ali ndi aluminium index index ≥65% amakhala kalasi yachiwiri ya aluminiyamu, ndi omwe ali ndi aluminiyamu yamankhwala. okhutira ≥75% amakhala kalasi yoyamba high-alumina njerwa. Chemical index ili ndi aluminiyamu. Kuchuluka kwa ≥80% kumakhala njerwa zapamwamba kwambiri za aluminiyamu.
