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 specific content is what gb/t2608-2012 brick: Quality assessment procedures, packaging, marking, transport, storage, and quality certificates. Suitable for siliceous refractory bricks.

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: 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: How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?: Mainly from the impurities to determine how much, generally less impurity single color brick.

Q: Why is the three oxidation of two silicon is very harmful impurities in silica brick: Can generate the material needs is the best way to see the impurity problem!! the first consideration is whether can get the material impurities with what method choice after the time! Miscellaneous reactions cannot have new impurity formation! Selected cannot and need material reaction reagent!

Q: How to improve the thermal conductivity of the coke silicabrick rate?: The content of SiO2 is 98.23% crystalline silica as raw material, with sulfite pulp liquid as binder, millscale and lime as mineralizer, by Jin Hongshi (TiO2) as additive, can improve the rate of thermal conductivity of silica brick for coke oven. When the rutile content is 1.5%, the coefficient of thermal conductivity of silica brick for coke oven is 2.66W/ (m.k).

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

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.

Q: High temperature refractory material?: Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, the refractory material used for special occasions.Now the definition of refractory materials, has not only depends on whether the refractoriness at 1580 DEG. Refers to the current refractories used in metallurgy, petrochemical, cement, ceramics and other production equipment with inorganic non-metallic materials.

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.
