Scope of application of sand-lime brick
It is an acidic fireproof material, highly resistant to acid slag or acid solution corrosion, but poor resistance to alkali corrosion; high softening point under load, reaching 1640 ~1680 ℃; poor resistance to thermal shock, Fire resistance degree 1690~1730℃, mainly used for coke ovens, hot blast furnaces, glass furnaces, carbon kilns, etc..
Characteristics of sand-lime brick
- High softening point under load.
- High thermal conductivity.
- Good resistance to thermal shock at high temperatures.
- Volume stability at high temperatures.
