General Industrial Furnace Bricks , Insulating Fire Brick High Temperature
High Alumina Bricks are produced with selected bauxite chamotte as main raw material, fired at 1450-1470 °C by advanced process with strict quality control.
High Alumina bricks have great features like high temperature performance, great corrosion and wear resistance, high bulk density, low iron content, etc. High Alumina bricks are extensively used in mining, metallurgy, cement, chemical and refinery and refractory industries.
These bricks are used in all kinds of industrial furnace and high temperature areas to prolong the lives of furnaces.

High Alumina Bricks,their typical properties include high refractoriness, crushing strenght, density, abrasion resistence and with increased resistence to molten metals, slags, glass and other chemici impacts. They are used to walls, rous and extremely stress parts of metalurgy aggregates (hot blast stoves, blast pipes, gorn of blast furnaces, torpedo ladles and pouring ladles for raw metal, casting ladles), shaft and rotary furnaces for firing lime and cement, linings of tunnel fonace of firing ceramics, turner blocks and ceramics burners' endings.
