Technical Highlights
Low Bulk Density: These high alumina fire bricks feature a low bulk density, reducing the overall weight of thermal equipment and enhancing energy efficiency.
Enhanced Thermal Insulation: The low thermal conductivity of these bricks ensures effective heat retention, contributing to energy savings.
Improved Mechanical Strength: Despite their low density, these high alumina fire bricks maintain high compressive strength, ensuring durability under load.
Description:
Characterized by low bulk density, maximum service temperature is 1350C., high cold crushing strength, size precision and hold the most stable and lowest thermal conductivity of all insulating refractory bricks at present.
The total weight of the furnace body and walls thickness can be reduced effectively, thermal efficiency and working condition can be improved, energy consumption can be lowered, and productivity and significant economic results can be achieved.
High alumina lightweight insulating refractory brick is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.
Applications:
By using the products widely in insulating layers of various thermal equipments for example blast furnace, hot blast furnace, coke oven and linings where no high temperatures melt corrosion occurs.
