Fire Clay Brick Corundum Mullite Brick Insulating Mullite Refractory Firebrick
Definition:
Fire Clay Brick Corundum Mullite Brick Insulating Mullite Refractory Firebrick refer to light-weight thermal insulation brick products with Al2O3 content of 30%-46%. With clay clinker or light clinker and plastic clay as the main principle, Fire Clay Brick Corundum Mullite Brick Insulating Mullite Refractory Firebrick is usually produced by the combustible method. Fire Clay Brick Corundum Mullite Brick Insulating Mullite Refractory Firebrick can also be produced by the chemical method or foam method to form a porous structure. The use temperature is 1200-1400℃. The refractory is characterized by high porosity, generally 40%-85%; low bulk density below 1.5g/cm3; low thermal conductivity, generally below 1.0W (m.K).
Compared with ordinary clay bricks, Fire Clay Brick Corundum Mullite Brick Insulating Mullite Refractory Firebrick are lighter in weight. The heat-insulating refractory products with Al2O3 content of 30%~48% made of refractory clay as the main raw material. Using refractory clay, floating beads, and refractory clay clinker as raw materials, adding binders and sawdust, after batching, mixing, molding, drying and firing, products with a bulk density of 0.3~1.5g/cm3 can be obtained. It accounts for more than half of the total output of heat-insulating refractory bricks, with tiny pores evenly distributed inside, with a high porosity. Therefore, it can be ensured that the furnace wall loses less heat, and the fuel cost will be reduced accordingly. Lightweight clay bricks also mean less heat storage, so heating and cooling are faster, allowing faster periodic operations. Fire Clay Brick Corundum Mullite Brick Insulating Mullite Refractory Firebrick are suitable for the temperature range of 900℃~1650℃.
Lightweight refractory bricks Advantage:
(1). good heat resistance, high temperature.
(2). small thermal expansion, good peeling resistance.
(3). good corrosion resistance.
(4). good chipping resistance.
Application:
Generally suitable for thermal surface refractory lining or other refractory back lining insulation layer.
Refractory lining or thermal insulation for industrial furnaces in petroleum or chemical industries, such as ethylene cracking furnaces, tubular furnaces, reforming furnaces for synthetic ammonia, gas generators and high temperature shuttle kilns.
Tunnel kiln, push board kiln, roller kiln, wood kiln refractory lining material for industrial and household ceramics.
