Wear Resistance High Alumina Brick / Heat Resistant Bricks For Hot Blast Furnace
1. Product Feature
High Alumina Bricks are produced with selected bauxite as main raw material, fired at 1450-1470 °C by advanced process with strict quality control. High Alumina bricks have great features like high temperature performance, great corrosion and wear resistance, high bulk density, low iron content, etc.High Alumina bricks are extensively used in mining, metallurgy, cement, chemical and refinery industries. These bricks are also used in all kinds of industrial furnace and high temperature areas to prolong the lives of furnace.
