Product description of high alumina universal arc firebrick
High alumina universal arc refractory brick is semicircle, and the other end is grooved. No matter how thick it is, it is flexible. Since arc refractory firebrick has no axis and slightly deviates in size, it can also be made into a circle. This refractory arc brick is used for spoons.
Advantages of high alumina universal arc firebrick
- Long service life, 210% longer than clay refractory bricks.
- The decrease of unit consumption may indicate the corresponding decrease of non-metallic inclusions in molten steel.
- Slag and molten steel have strong corrosion resistance, which can be seen from the high section aluminum bricks after use.
