Product Description

Product Description

Product Introduction of Silica Brick:
Silica brick is an acid refractory material composed of tridymite, cristobalite and a small amount of residual quartz and glass phase. Silica bricks have good resistance to acid slag erosion. The refractoriness under load is as high as 1640~1670ºC, and the volume is relatively stable under high temperature for long-term use.

Features of Silica Brick:
1.Good resistance to acid slag erosion.
2.High strength at high temperature. 
3.Little dimensional change when using at high temperature for a long time.

Application of Silica Brick:
It is mainly used for the chamber and combustor of coke oven, regenerator chamber and cinder chamber of steelmaking open hearth furnace, soaking pit, refractory material of glass melting furnace, vault and other load-bearing parts of ceramic kiln .It is also used for high temperature load bearing parts of hot blast furnace and roof of acid open hearth furnace.
