Hot blast furnace&glass furnace applied refractory silica brick
Introduction of refractory silica brick
Refractory silica brick is dense shaped refractory material and the main materials is SiO2.
Features of refractory silica brick
1) Silicon oxide is above 95%.
2) Good acid glass furnace 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.
Our capacity:
We have 2 tunnel kiln with 168meters length and 25 sets of compressing machine with 300-500tons capacity. with the annual capacity more than 50,000tons .
Application of refractory silica brick
They are widely used for hot blast furnace,coke oven,glass furnace.The products can be made according with the customers' requirement.
