Light Weight Aluminum Insulating Fire Brick


Supply Ability:150T/D
Raw materials:insulation material adopting organic matter
Application:cement, electric power, metallurgy, chemical industry and other industry




It is an new light weight refractory product developed by our company according to the demand. Featured by high temperature resistance, low conductivity, low iron content, large compressive strength and good thermal stability, it can be used directly as the lining for industrial furnaces.


Light weight 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.


Light Weight High Alumina Insulating Brick is widely used in lining or insulating layers of various industrial furnaces, and kilns in petrochemical, machinery, ceramic industry.
