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.

Q: Why will expand when heated brick: In the process of SiO2 drying, the four crystalline transformation points of 117, 163, 180~270 and 573 DEG C are found, among which the volume expansion caused by the 180~270 is the largest.

Q: What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you: The main damage of silicon carbide side wall brick is stress damage, not chemical erosion. Chemical damage is formed prior to the formation of the groove, and the damage to the chemical erosion is little after the formation of the groove.

Q: The introduction of silica brick: The characteristics of silica brick:Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.The use of silica brick:Mainly used for masonry brick oven carbonization chamber, a combustion chamber and a partition wall, glass furnace and kiln roof, pool wall, high temperature hot blast furnace, glass furnace, load-bearing pool wall, hot blast stove, baking furnace of carbon bearing part of high temperature furnaces etc.. Rongsheng with refractory

Q: What is acid refractory?: Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.

Q: Semisilica brick, clay brick, high alumina brick and what is the difference?: The share of A12O3 and SiO2 is different

Q: The brick is mainly used in the place?: Partitions used in coking and combustion chambers for coke ovens

Q: Can iron oxide be used as refractory material?: Iron oxide can not be used as refractory material, but it can be used as refractory additive. Iron oxide can be used as pigment

Q: The high thermal conductivity of silica brick and traditional brick what is the difference?: Tridymite content high thermal conductivity silica brick is 70%, tridymite content of traditional brick is 60%, tridymite content high thermal conductivity of silica brick than tridymite high content of 10% traditional brick,

Q: Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450: Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.
