Advantages of Alumina Magnesia Carbon Brick
1.High refractoriness: They can endure extremely high temperatures, up to over 1600°C, making them suitable for harsh high – heat environments.
2.Good slag resistance: Resistant to the corrosive effects of various slags in metallurgical processes, maintaining structural integrity.
3.Excellent thermal shock resistance: Withstand rapid temperature changes without cracking, ensuring long – term service.
4.High mechanical strength: Capable of bearing mechanical loads during industrial operations, ensuring durability.
Application of Alumina Magnesia Carbon Brick
Alumina magnesia carbon bricks have wide applications in the metallurgical industry. In steel – making converters, they line the interior walls, enduring the extreme heat of molten steel and the corrosive action of slag. In ladles, these bricks are used to transport and hold the molten metal, ensuring heat preservation and preventing leakage. They are also applied in electric arc furnaces, playing a crucial role in withstanding high – temperature smelting processes and extending the service life of the equipment.
