Heat Resistant Alumina Ceramic Lining Bricks Descriptions:

 

Heat Resistant Alumina Ceramic Lining Bricks are made of high purity fused corundum and imported tabular alumina. After mixing, molding, drying and firing under high temperature in tunnel kiln, they have the advantage of high refractoriness, good thermal shock resistance, good strength under high temperature, good corrosion resistance, good slag resistance, small expansion factor, low creep and good strip resistance. Primarily are used for the key parts of the industrial furnaces of steel, electronics, petrochemical, fertilizers, non-ferrous metals, refractory materials and so on .The dimensions, physical and chemical indexes and service life have all achieved and surpassed the standards of similar products home and aboard.
