Definition:
Light Weight Insulating Bricks 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, it is usually produced by the combustible method. It 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, Light Weight Insulating Bricks 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. Light Weight Insulating Bricks are suitable for the temperature range of 900℃~1650℃.
Advantage:
1. Light Weight Insulating Bricks has advantages with small bulk density, high cold crushing strength, and high refractoriness under load, small dimension tolerance and good thermal shock resistance.
2. Light Weight Insulating Bricks has the lowest and most stable thermal conductivity in various insulating refractory bricks
3. Light Weight Insulating Bricks can reduce the total weight of furnace body and the thickness of furnace wall effectively, improve heat efficiency, lower energy consumption, improve work conditions and production efficiency, and considerable economic benefit can be obtained.
Application:
Light Weight Insulating Bricks is mainly used for the partition of coking chamber and combustor of coke making furnace, regenerator chamber and cinder chamber of steelmaking open hearth furnace, soaking pit, refractory material of glass melting furnace and sintering furnace of ceramics and other kiln vault and other load-bearing parts.
It is also used for high temperature load bearing parts of hot blast furnace and acid open hearth furnace top.
