High Temperature Resistance Alumina Fire Brick50

1. Product Name:High Temperature Resistance Alumina Fire Brick

2. Product Description:China supplied high temperature resistance alumina fire brick for boiler with competitive price High Temperature Resistance Alumina Fire Brick Introduction to alumina fire brick Alumina fire brick is a kind of refractory material. It is an aluminum silicate refractory product with aluminum oxide (Al2O3) content higher than 48%. The main component of this refractory brick is AL2O3.. It is formed and calcined from alumina or other raw materials with high alumina content. High thermal stability, refractoriness above 1770?. It has good slag resistance and is used for lining steel-making electric furnaces, glass melting furnaces, cement rotary furnaces, etc. Product performance of alumina fire brick 1. Refractoriness of alumina fire brick The refractoriness of alumina fire brick is higher than that of clay bricks and semi-silica bricks, at 1750~1790?, which belong to advanced refractory materials. 2. Load softening temperature of alumina fire brick 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. alumina fire brick, but because mullite crystals do not form a network structure, there is still no silicon at the load softening temperature. Brick high. 3. Slag resistance of alumina fire brick alumina fire brick 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. Classification of alumina fire brick 1. Classified by Al2O3 content in alumina fire brick Class?: Al2O3 content>75% Class?: Al2O3 content is 60~75% Class?: Al2O3 content is 48-60%. If Al2O3 content is higher than 80%, it is called super alumina fire brick If Al2O3 content is higher than 90%, it is called corundum brick. 2. Classification of alumina fire brick by firing process It can be divided into fired alumina fire brick and unfired alumina fire brick. The firing temperature of the first and second grade alumina fire brick is 1500?-1600? and 1450?-1500? respectively, while the third grade is lower. High-alumina non-sintered bricks mainly refer to phosphate high-alumina. 3. Classification of alumina fire brick by mineral composition It can be divided into five types: low mullite, mullite, mullite, corundum, corundum and corundum; 4. Classification of alumina fire brick according to different shapes It can be divided into standard alumina fire brick, special-shaped alumina fire brick and special alumina fire brick; 5. Classification of alumina fire brick according to their properties It can be divided into ordinary alumina fire brick and special alumina fire brick (thermal shock resistance, low creep, anti-stripping alumina fire brick; 6. Classification of alumina fire brick by use It can be divided into high-aluminum and high-alumina bricks, hot-blast stove high-alumina bricks, steel-making electric furnace top high-alumina bricks, Shenggang barrel high-alumina bricks, and inner cast high-alumina bricks.
