Rotary Furnace 1770℃ Aluminum Silicate Fire Retardant Bricks


Definition:

High Alumina Bricks is an aluminum silicate material which content of more than 48% alumina. It is formed and calcined from alumina or other raw materials with high alumina content. The advantage of this material are high thermal stability, refractoriness above 1770℃,good slag resistance.rmal stability, fire resistance above 1770℃. It has good slag resistance and is used for lining steel-making electric furnaces, glass melting furnaces, cement rotary furnaces, etc.


This product has the advantages of low temperature creep, strong corrosion resistance and good thermal shock stability.


High Alumina Bricks could be made Standard form, normal standard, shaped and special shaped bricks.Can be used in various kilns because of its cheapness and general tray package. Among all of the refractory materials, it is the mostly used in the key positions.Molding method: it has down draft kiln and tunnel kiln and the general sintering temperature is 1360-1480 degrees. It is a kind of aluminosilicate refractory product which aluminum oxide (Al2O3) content is higher than 48%.


Advantage:


• Resistance to High temperature, Resistance to erosion, resistance to abrasion
• Excellent compression strength
• Resistance to acid and alkali.
• Excellent heat stability

Application:

High Alumina Andalusite Fused Mullite Refractory Bricks that mainly used for lining blast furnaces, hot blast stoves, electric furnace tops, blast furnaces, reverberatory furnaces, rotary kilns. In addition, high-alumina bricks are also widely used as open-hearth regenerative lattice bricks, plugs for pouring systems, nozzle bricks, etc.


However, the price of high alumina bricks is higher than that of clay bricks, so it is not necessary to use high alumina bricks where clay bricks can meet the requirements.
