High density alumina universal arc firebrick production
The high density alumina universal arc firebrick is mainly used as the lining of the steel barrel. The vertical joint of the universal arc brick is smaller, which is 70% less than the straight joint of the standard firebrick. It has good applicability and expansibility.
Advantages of high density alumina universal arc firebrick
- No deformation
- High fire resistance
- Regular shape
- Smooth flow path
- Good cracking resistance
- No spalling and strong erosion resistance
Standard size:
There are many different sizes of universal arc firebrick, welcome to customize by drawing!
