Corundum brick
Corundum brick introduction:
Corundum brick uses high-quality corundum as main raw materials. In the
making process, firstly we should deploy a scientific formula and add
excellent performance additives, then the bricks will be moulded under
high presure and sintered under high temperature, finally made the
corundum bricks
Advantages of corundum brick:
Corundum brick can be divided into sintered corundum brick and fused
corundum brick. Corundum brick has advantages of high strength,
excellent wear resistance and strong anti-slag erosion, long service
life and other characteristics. Corundum brick and chrome corundum
brick, corundum mullite brick all can reduce the number of shutdown
maintenance, thus saving maintenance costs, improve the furnace
operating rate.
Corundum brick uses:
Corundum brick is a kind of high quality furnace lining materials and
kiln materials for large blast furnace, rolling furnace and melting
furnaces and kilns for refractory material, glass, chemical, ceramic,
nonferrous metallurgical.
