Main Characters of Alumina Carbon Bricks
Alumina carbon brick has excellent slag resistance and thermal shock resistance. Compare to Magnesia Carbon bricks, alumina carbon bricks has better resistance to alkali corrosion and TiO2 slag.
2. Applications:
According to different production processes, it is divided to non-burning and burning alumina carbon bricks. Non-burning bricks are widely used in hot metal pretreatment equipment of blast furnace and steel ladle. Burning bricks are widely used for sliding nozzle and sliding gate of the continuous casting system.
