The scope of application of silica bricks

It is an acidic refractory material, with strong resistance to acidic slag or acidic solution corrosion, but poor resistance to alkaline corrosion; high load softening temperature, reaching 1640~1680℃; poor thermal shock resistance, refractory degree 1690~1730℃, mainly used for coke Furnaces, hot blast furnaces, glass kilns, carbon roasting furnaces, etc.

Characteristics of silica brick

1. High softening temperature under load.
2. High thermal conductivity.
3. Good thermal shock resistance at high temperatures.
4. High-temperature volume stability.
