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.

Q: Physical solid waste disposal: Reduce crack production and improve yield. The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem

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

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: Semisilica brick, clay brick, high alumina brick and what is the difference?: This is a kind of refractory material is divided into three types: semisilica brick (A12O315 ~ 30%), clay brick (A12O330 ~ 48%), high aluminum brick (A12O3>48%).

Q: The United States of our brick anti-dumping duties?: . According to the relevant legal procedures, the United States International Trade Commission will make a final ruling on the anti dumping industrial injury before January 6, 2014, if an affirmative determination, the U.S. Department of Commerce will be involved in product release tax anti-dumping order.

Q: Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450: That is because the brick load softening point the maximum temperature is 1450 degrees.

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: What is the silica refractory products?: Refractory brick with silica content greater than 90%.

Q: High temperature refractory material?: Special materials often use AZS brick (i.e. corundum brick), corundum brick, magnesia chrome bricks, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Insulation refractories are often used diatomite products, asbestos products, insulation board. Unshaped refractories are often used refractory castable, refractory clay, refractory ramming material, refractory plastic and fettling material, fire resistance, gunning, refractory cast material, fireproof coating, lightweight refractory castable, gun mud.

Q: Such purpose and scope please give me detailed points thank you: Mainly used for coke oven carbonization chamber and the combustion chamber wall, open hearth furnace regenerator and a sediment chamber, soaking furnace, glass furnace, refractory materials and ceramic brick kiln, kiln vault and other load-bearing parts. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
