Description
Alumina Magnesia Carbon brick offers several advantages, including excellent corrosion resistance, resistance to spalling, and remarkable durability against the scouring effects of molten steel. Its safe usability, reduced steel and slag adhesion, and easy unpacking further contribute to its appeal.
This refractory brick finds significant application in the lining of steel ladles under harsh conditions. Specifically, it is utilized in the molten pool part and the bottom part of continuous casting large tundishes, as well as the refining package outside the furnace.
Advantages of Aluminum Magnesia Carbon Brick for Steel Ladles:
- Exceptional resistance to erosion.
- Effective prevention of flaking.
- Well-balanced resistance to erosion.
- Ensured safety during use.
- Reduced slag adhesion on steel.
- Easy and convenient unpacking process.
