Product Description

Low Creep High Quality Silica bricks for glass furnaces, coke ovens and foundries according to customer requirements;

In general, silica bricks are used for coke and annealing furnace, covering the walls of the furnaces, in high heat areas of melting furnaces.

Advantage:
1) Silicon oxide is above 95%.
2) Good acid erosion resistance.
3) High softening point with temperature.
4) No shrink in burn repeatedly.
5) Temperature of refractoriness under load is above 1650º C Stable Capability, High Quality, Excellent Service, Competitive price is the most important advantage of our products.
