Product details
Product Features: High-alumina bricks for blast furnaces are manufactured using high-grade calcined bauxite clinker as the primary raw material, followed by high-pressure forming and high-temperature sintering. The main mineral phases are mullite and corundum, giving the product excellent high-temperature physical properties and outstanding resistance to chemical erosion. These bricks are widely used in various sections of blast furnace linings.
