Product Description:

65% Al2O3 Min High Alumina Insulating Fire Brick     


High alumina insulating fire 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.

This series of High Alumina Insulating Fire Brick are made of selected high alumina bauxite, kaolin caly, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature. 


Product Applications:

High alumina insulating fire brick are ideal for use in the below applications 

Building materials for blast furnace

Building materials for hot-blast stove

Building materials for coke oven

Building materials for steel making furnace

For construction material in steel industry

For ladle


Product Advantages:

CNBM has success in its High alumina insulating fire brick due to their cost-effectiveness and excellent insulating properties. The refractoriness of magnesia chrome bricks are more than 2000°C, and the refractory under load is a above 1550°C.Good steady volume in high temperature, the performance of meeting sudden cold and sudden hot is better than magnesia bricks. 


Main Product Features:

Excellent thermal stability

High refractoriness under load

Chemical stability and anti-corrision

Small high temperature creep rate

Excellent thermal shock resistance
