High Alumina Universal Arc Brick for Kiln

Product introduction of high alumina universal arc brick

High alumina universal arc bricks are mainly used as the lining of steel drums. They are one of the necessary bricks commonly used in steel drums. They have good applicability and expansibility. They can be used for steel drums of different specifications and sizes and choose efficient masonry methods.

Features of high alumina universal arc brick

High fire resistance

No deformation

Shape rules

Good crack resistance

No peeling and erosion resistance

Details of High alumina universal arc brick

  1. High service life, more clinker clay bricks increased by 210%.
  2. The advantage of high aluminum universal arc is shown by the reduction of unit consumption. The reduction of unit consumption can also indicate the corresponding reduction of non-metallic inclusions in molten steel.
  3. After use, the inspection found that the corrosion resistance of the fracture surface of high alumina brick to slag and molten steel is better than that of multi clinker clay brick.
  4. The roundness of both ends of high alumina universal arc refractory bricks can be adjusted by moving back and forth during bricklaying, so it is very convenient to lay refractory bricks, and the brick joints can generally reach 1mm.
