400C Refractories High quality manufacturer fused magnesia alumina spinel for refractory fireproof 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.
400C Refractories High quality manufacturer fused magnesia alumina spinel for refractory fireproof 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.

 

 

400C Refractories High quality manufacturer fused magnesia alumina spinel for refractory fireproof brick refers to a heat-insulating refractory product made of bauxite with an Al2O3 content of not less than 48%.
