General Information

Ceramic firing kiln refractory Silica Brick Description:

Refractory Silica Brick is mainly made of top class silica, via shaping and burning under the high temperature,

Possesses high temperature resistant, high strength and low impurities, etc.

It is mainly used for blast furnaces and hot blast stove.

 

Features

Ceramic firing kiln refractory Silica Brick Advantage:

1) Silicon oxide is above 95%.

2) Good acid erosion resistance.

3) High softening point

 

Applications:

Light weight silica bricks are primarily used for furnaces and kilns in metallurgy, steel, power, chemical industry, and electric power and machine building etc areas

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 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: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:What are the materials for refractory materials? What are their names?
Classification of chemical components of refractory materialsAccording to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
Q:The formula in the refractory brick, and firing curve, who knows?
Add 1.8-2.2% of the total weight of the main raw material, and then add lime milk, rolling for 10-15 minutes, and finally add pulp, rolling for 10-15 minutes, out of the mill, forming billet.
Q:The introduction of silica brick
Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature.
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: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 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: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
