Product description of high alumina arc brick
High alumina arc firebrick is mainly used as the lining of large steel barrels, and it is one of the necessary common brick types for large steel barrels. It has good applicability and scalability, and can adopt different specifications of products and choose efficient masonry methods for different sizes of large steel barrels.
Features of high alumina arc brick
High fire resistance
No deformation
Strong erosion resistance
Good cracking resistance
Details of high alumina arc brick
- High service cycle, more clinker clay bricks increased by 210%.
- The advantages of high aluminum universal arc are shown by the reduction of unit consumption. The decrease of unit consumption can also indicate the corresponding decrease of nonmetallic inclusions in molten steel.
- The corrosion resistance of high-alumina brick to slag and molten steel is better than that of multi-clinker clay brick after use.
- High aluminum universal arc firebrick can be used in bricklaying because of roundness at both ends. Move back and forth to adjust the roundness, so it is convenient to build firebrick, brick seam can generally reach 1 mm.
