Use of Sunrise Refractory Mullite Insulation Brick For Sales

Mullite insulation bricks are divided into lightweight insulation bricks and heavy insulation bricks, which have the advantages of green environmental protection and no pollution. Due to their different densities, the use of mullite insulation bricks varies. Zhengzhou sunrise Refractory Co., Ltd. is committed to producing quality refractory materials with complete varieties, and the production of mullite insulation bricks has been widely recognized in the industry.
Mullite brick refers to a high alumina refractory material with mullite as the main crystal phase. Generally, the alumina content is between 65% and 75%. In addition to mullite, the mineral composition contains a small amount of glass phase and cristobalite, and a higher amount of alumina also contains a small amount of corundum. Mainly used in hot stove top, blast furnace body and furnace bottom, glass furnace regenerator, ceramic sintering kiln, oil cracking system dead angle lining. The mullite brick has a high degree of refractoriness and can reach above 1790 °C. The load softening start temperature is 1600 to 1700 °C. Normal temperature compressive strength is 70 to 260 MPa. Good thermal shock resistance.
Our mullite bricks are available in sintered mullite bricks and fused mullite bricks. The sintered mullite brick is made of high alumina bauxite clinker as a main raw material, and a small amount of clay or raw bauxite is added as a binder, which is formed by molding and firing. The electric melting mullite brick is made of high alumina, industrial alumina and refractory clay, and is added with charcoal or coke fine particles as a reducing agent, and is formed by reduction electrofusion after molding. The crystal of fused mullite is larger than sintered mullite, and the thermal shock resistance is better than that of sintered products. Their high temperature performance depends mainly on the alumina content and the uniformity of the mullite phase and glass distribution.
Main features of mullite insulation brick:
1. Green, non-toxic, non-corrosive, safe to use.
2. Good adaptability to cement.
3. The lightweight thermal insulation brick is foamed by a foaming mechanism to obtain a foam having a uniform bubble diameter.
4. Excellent foaming performance, the foaming multiple can reach more than 30 times.
What is the use of mullite insulation bricks? The mullite lightweight insulation brick is an insulated refractory product made of mullite as the main raw material. The mullite lightweight insulation brick is resistant to high temperature, high strength, low thermal conductivity and can directly contact the flame, and is suitable for the lining of various industrial furnaces. Mainly used in hot air furnace top, blast furnace body and furnace bottom, glass melting furnace regenerator, ceramic sintering kiln, petroleum cracking system dead angle lining, etc.
Zhengzhou sunrise Refractory Co., Ltd. produces a full range of insulation bricks, quality assurance, professional business team and first-class technical guidance to help customers find suitable products, and look forward to serving more kiln projects.
