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.

$Hot Blast Furnace Applied Refractory Silica Brick$

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: Good thermal shock resistance. In use, more high viscosity glass phase can be formed, and the masonry brick joint and the working surface are dense and the masonry is complete, which is beneficial to improve the impermeability of the masonry and reduce the erosion effect of the slag on the masonry.

Q: Such purpose and scope please give me detailed points thank you because I am learning stage: Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.

Q: Glass kiln brick for physical and chemical indicators?: Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.

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

Q: Which material is good for furnace refractory?: Kiln types of refractories is very extensive, selection of refractory materials according to the type of furnace furnace temperature and use of selected refractory material, refractory material is divided into custom products of refractory bricks and unshaped refractory castable series products. According to chemistry, it is divided into acidic, neutral and alkaline materials.

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.

Q: The difference between clay refractory bricks and refractory brick in the application.: Clay brick features good thermal shock resistance and low price, but high temperature performance is not well integrated, and the long-term use temperature is not higher than 1300 degrees. It is widely used in low temperature parts of various kilns.

Q: Why in the production of the brick to detect the volume density: Density is the property of material, different density of materials, density of the same kind of material is not up to standard, affecting performance.
