Classification uye general hunhu hwe yakakwirira alumina zvidhinha

Iyo yakakwirira-alumina refractory inogona kuiswa maererano nehuwandu hwemhando, iyo inogona kukamurwa zvakaenzana muzvikamu zvina: kune yekutanga-yepamusoro-yepamusoro-aluminium zvidhinha, yechipiri-yepamusoro-yepamusoro-alumina zvidhinha, yechitatu-chikamu chepamusoro-aluminium zvidhinha uye yakakosha. -level high-alumina zvidhinha. Panyaya yeindasitiri yakajairika pfungwa, zviratidzo zvemakemikari Avo vane aluminium content ≥55% vanova yechitatu-giredhi yepamusoro-aluminium zvidhinha, avo vane kemikari index aluminium content ≥65% vanova yechipiri-giredhi yepamusoro-alumina zvidhinha, uye avo vane kemikari index aluminium. zvemukati ≥75% inova yekutanga-giredhi yakakwirira-aluminium zvidhinha. Chemical index ine aluminium. Huwandu ≥80% inova yepamusoro yakakwira alumina zvidhinha.
