Product Description
Characteristics of refractory insulation bricks
A. Refractoriness The refractoriness of high alumina bricks is higher than that of clay bricks and semi-silica bricks, reaching 1750~1790℃, which belongs to advanced refractory materials. B. Load softening temperature Because high-alumina products have high Al2O3, less impurities, and less fusible glass bodies, the load softening temperature is higher than that of clay bricks. However, because mullite crystals do not form a network structure, the load softening temperature is still not as high as that of silica bricks. C. Slag resistance High alumina bricks contain more Al2O3, which is close to neutral refractory materials, and can resist the erosion of acidic slag and alkaline slag. Because of the inclusion of SiO2, the ability to resist alkaline slag is weaker than that of acidic slag.
