Silica Brick Description

High quality silica a 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.

Silica Brick 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.

Application of silica brick:

They are widely used for hot blast furnace, coke oven, and glass furnace. The products can be made according to customers' requirement.

$Silica Brick Refractory For Hot Blast Furnace$

Q: The introduction of silica brick: The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass

Q: Semisilica brick interpretation: High temperature volume stability. Volume change is small.

Q: Why is the new trend of the high thermal conductivity of silica brick: The high thermal conductivity of silica brick all inherits the advantages of traditional coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity.

Q: What is the main material of silica brickIt's common, the kind we see so often!: More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance.

Q: Glass kiln brick for physical and chemical indicators?: Glass kiln with high quality silica brick with silicon oxide content, low melt index, mainly used for glass kiln crown, parapet, wall hanging, small furnace arch superstructure and regenerator.

Q: Why is the three oxidation of two silicon is very harmful impurities in silica brick: Heating calcination is the best way to extend this sort of impurity removal. Remove impurities

Q: Can not use it two brick: The softening temperature is up to 1640~1670 DEG C, and the volume is stable at high temperature for a long time.

Q: Common bond brick?: Lime should contain a lot of active CaO, I decompose CaCO3 and MgCO3 not more than 5%, Al2O3+Fe2O3+SiO2 no more than 5%. When the content of large particles, burned Ca-CO3 and over burned lime, the product produced caves, affecting the quality of products.

Q: How to improve the thermal conductivity of the coke silicabrick rate?: To improve the thermal conductivity of silica brick for coke oven rate method:Manufacture of high density and high thermal conductivity of silica brick, adding additives such as CuO, Cu2O, TiO2, Fe2O3, (FeO), can improve the thermal conductivity of silica brick.
