ALUMINA-MAGNESIA-ENRICHED SPINEL CARBON BRICKS

摘要

PURPOSE:To provide refractory bricks ensuring an adequate level of permanent linear expansion coefficient comprising an alumina-magnesia-enriched spinel carbon bricks to which electrofused magnesia-enriched spinel starting material reduction in antislugging properties. CONSTITUTION:10 to 80wt.% of an electrofused magnesia-enriched spinel starting material containing more than 95wt.% of the total MgO and Al2O3 at a MgO/Al2 O3 weight ratio of 50/50 to 95/5, 3 to 60wt.% of a carbonaceous starting material and 10 to 85wt.% of an alumina starting material are used for the production.
