General Information

Aluminium silica brick is universal materials for the lining of molten pretreatment equipments of molten iron tank, torpedo car, etc. The products are shaped by machine power by using dense bauxite clinker and brown fused alumina as base materials and adding high quality SiC fines and high purity flake graphite. It has the advantages of excellent slag resistance, thermal shock resistance, good resistance to mechanical erosion, abrasion resistance, etc.

 

Features

1.High purity

2.Long service life

3.Accurate size tolerance

4.Pure color

5. Luster appearance

6..Good thermal conductivity
7.Good creep resistance

Application of the Acid refractory silica bricks  

Silica brick is mainly used for Coke oven, glass kiln, hot-blast stove, tunnel kiln,Acidic furnace non-ferrous metal smelting and some other thermotechnical equipment in good furnace building materials.

Q:Can iron oxide be used as refractory material?
Is widely used in this area. Mentioned refractory material of high school textbooks generally refers to three two aluminum oxide (alumina), alumina is also used as a refractory material, refractory crucible, porcelain, artificial gemstones.
Q:Semisilica brick, clay brick, high alumina brick and what is the difference?
The share of A12O3 and SiO2 is different
Q:Brick
The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass. Tridymite and cristobalite and quartz remaining at low temperature due to phase change, volume changes greatly, so the brick thermal stability at low temperature is very poor. In use, under 800 degrees Celsius, slowly heating and cooling, so as not to produce cracks. The use of temperature in blast furnace so should not be below 800 DEG on.
Q:What is the main material of silica brick
An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.
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:The brick is mainly used in the place?
Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
Q:The hot blast stove when the temperature did not rise against the brick interface decreased
How to keep the brick masonry temperature not lower than 600 DEG C, while the exhaust temperature is not higher than 400 DEG C.
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:Such purpose and scope please give me detailed points thank you
Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.
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.
