THE FEATURES OF HIGH ALUMINA INSULATION BRICK

High-Alumina insulation brick is a kind of insulation material adopting organic matter as ignition loss substance.

High-Alumina insulation brick has small volume density, good insulation effect,high mechanical intensity, small thermal conductivity and long service life.For various industrial kilns & furnance.

High-Alumina insulation brick is a kind of sessential refractory for energy saving and temperati\\ure preservation. 

High-Alumina insulating clay brick can be used auxiliary with other lining materials for the coke oven to have better insulation effect and save energy.
