Refractory Al2O3 30-48% Fireclay Brick For Industrial Furnace Glass Kiln
1: Refractoriness 1580℃-1750℃, Refractoriness under load is 1250℃-1450℃.
2. Fire Brick is used for Blast Furnace, Hot Blast Oven, glass kiln and other industrial furnace in high termature.
3. The Product shape has standard shape 230x114x65mm, and other special shape. the different mould is required.
4. Calcined fireclay is the raw materials, refractory clay as the binding agent.
5. Fireclay brick is acid refractory, more acid more SiO2 content, resistance for Acid slag.
6: Fireclay refractory brick has good thermal shock resistance, high refractoriness under load, low creep, can be used in furnace lining as glass oven, calcinator.
