1790C Low Creep High Alumina Heat Resistant Bricks
Low Creep High Alumina Refratory Standard Shape Brick is an ideal insulating refractory refractory material, with advantages of high strength, low thermal conductivity, good insulation property and low price. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.
Light weight high alumina brick is also called high alumina
insulating brick. It contains more than 48% Ai2O3 and mainly
consists of mullite and glass phase or corundum. It is usually made
of high bauxite and a small amount of clay. After the raw materials
are grounded, it is made into mud. Then it is cast and molded and
fired at 1300~1500℃. Sometimes industrial alumimum is used to
replace bauxite. Inorganic matter is added as ignition loss
substance in order to increase the porosity of the refractory.
