Fused α-corundum brick is mainly composed of α-Al2O3, which has high temperature resistance, strong alkali resistance, compact structure, excellent chemical stability, strong wear resistance, and is far more resistant to various slags than other aluminum silicates. It is an ideal material for metallurgical electrolytic cells and sliding rail bricks for heating furnaces.
Fused β-corundum bricks are mainly composed of β- Al2O3, with dense structure and strong spalling resistance, especially showing extremely high corrosion resistance to strong alkali vapor, no pollution to molten glass, and are used for upper structures with less glass raw materials scattered.
Fused α-β corundum brick is composed of about 50% of α- Al2O3 and β- Al2O3. The two crystals interlace to form a dense structure, which has excellent alkali resistance, and the corrosion resistance of molten glass is comparable to that of AZS bricks and does not pollute the glass liquid. , Mainly used for high-grade glass furnace working pool wall and pavement, forehearth and passage, etc.
