Alumina-graphite bricks

Burned microporous alumina-graphite bricks are made of dense corundum, super-grade bauxite clinker, high-temperature electrically calcined anthracite, graphite, and silicon carbide as the main raw materials. Add the phenolic resin as a binder and adopt the micropore generation process. The bricks are fired in a high-temperature reducing atmosphere after being formed.

Burned microporous alumina-graphite bricks are suitable for the middle and lower parts of large blast furnaces, furnace waist, furnace belly, furnace hearth and furnace bottom.
