Furnace 230*114*65
High quality silica brick is made of silicon raw material, the
content of SiO2 is above 95%. And the content of Al2O3 is below
1.0%. Our factory produces various kinds of refractory products.
The products can be made according with the customers' requirement.
Feature:
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.
Advantage:
The silica brick for coke oven has low alkali and low content of
residual quartz.
The silica brick has high strength and refractoriness under load.
The silica brick also has strong ability in acid slag resistance.
This silica brick is used to the walls, hearth or other parts of
the combustion chamber, and carbonization chamber
Application:
They are widely used for hot blast furnace, coke oven, and glass
furnace. The products can be made according to customers'
requirement.
