Corundum Mullite Bricks for Blast Furnaces

Properties of Products: Corundum-mullite bricks for blast furnaces are made from fused or sintered corundum and mullite, being pressed with high pressure and sintered in high temperature. Main mineral compositions are mullite and corundum phases. White appearance, exact dimensions and excellent physical/chemical properties in high temperature make them as one of the materials used for Ceramic Cup of blast furnaces of big capacities. 

Properties of Products: Compounded brown corundum bricks have the properties of High melting point, high strength, low thermal expansion and steady chemical features, resist alkaline and acid erosion better. Mainly service as one of the materials for Ceramic Cup of blast furnaces.

Properties of Products: The main raw materials for producing sillimanite bricks for blast furnaces are sillimanite , quality bauxite and flint. After pressing and sintering, mullite phases are majority of the mineral phases, Mainly used for the throat, tap hole and air port of blast furnaces.

Properties of Products: Mullite bricks for blast furnaces are made from artificial fused or sintered mullite, being pressed with high pressure and sintered in high temperature, main minerals are mullite. These products have the peoperties of low apparent porosity, high RUL, excellent creep result and anti-chemical erosions. They are used as super grade refractory materials for hot-blast stoves as well as one of the Ceramic Cup materials for large blast furnaces.
