Corundum Mullite Bricks Price

Corundum mullite bricks from Rongsheng refractory are made from selected synthetic mullite and high purity corundum. The raw materials are molded and sintered under high pressure and temperature into a finely manufactured corundum bricks. Advantages of the product includes high RUL (refractory under load) capacity, low apparent porosity, fine thermal shock resistant ability and good abrasion resistance. The product can be used for steelmaking furnaces, nonferrous smelting furnaces, boilers or refuse incinerators.
