Description:

Silica bricks for hot stoves feature sharp dimension,low expansion,little residual quartz, low true density.low creep rate,good thermal shock resistance upon 600°C. It mainly used at high temperature area include arch and upside of hot stove and upside of checker.

Andalusite bricks are mainly used in the cooling wall of blast furnace, chemical and ceramic industry, the door of coke oven, or as the lining and checker of hot blast furnaces.


 

Application:

1 Building materials for steel making furnace

2 Kiln car building                      

3 For glass furnace

                     

 

Advantage:

1.Competitive Price. Make the products competitive in your market.

2.Abundant Experience. Prevent cracks and twist in bricks.

Superior Quality Silica Light Weight Insulation Refractory Brick


Q: The specific content is what gb/t2608-2012 brick
The provisions of the brick classification, technical requirements, test methods,
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.
The ability of alkali resistance is poor, the thermal shock stability is the worst, and it is scrapped at one time. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.
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: How much is the highest melting point of silicon?
. True density 2.35g/cm3. With acid resistance, slag erosion performance. Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into quartz in the body. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. The total volume of heating to 1450 DEG about 1.5~2.2% expansion, the residual expansion will make cutting seam sealing, ensure masonry tightness and good structure strength, so that the brick load softening temperature will reach 1750 degrees Celsius above 1620 degrees in the case of the highest melting point.
Q: Semisilica brick, clay brick, high alumina brick and what is the difference?
The share of A12O3 and SiO2 is different
Q: What role does silica play in refractories?
The production of clay brick refractory clay raw material is natural, its main mineral is kaolinite (formula Al2O3 - 2SiO2 - 2H2O), clay brick containing SiO2 in 45% ~ 65%, belongs to the weak acid refractory materials, have a certain ability to resist acid slag, but easy to be alkaline slag erosion.
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: Common bond brick?
Manufacturing for silica brick binder hi-li sulfate pulp waste liquid and lime milk. When lime milk is used as a bond, it acts as a plasticizer. To increase the strength of lime brick in the drying process, as mineralizer in the firing, promote the transformation of quartz.
Q: Physical solid waste disposal
Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
