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 and high refractoriness under load, 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 blast furnace                      

2 Building materials for hot-blast stove                      

3 Building materials for coke oven                      

4 Building materials for steel making furnace

5 Kiln car building                      

6 For glass furnace

Refractory Silica Bricks Used in Hot Blast Furnace

Refractory Silica Bricks Used in Hot Blast Furnace


Q: The specific content is what gb/t2608-2012 brick
The provisions of the brick classification, technical requirements, test methods,
Q: The introduction of silica brick
An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.More than 94% silica content. 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. When heating up to 1450 degrees, the total volume of 1.5~2.2% expands, and the residual expansion can close the kerf and ensure the airtight and structural strength of the masonry.
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: How much is the highest melting point of silicon?
Acidic silica brick refractories, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature. More than 94% silica content.
Q: Glass kiln brick for physical and chemical indicators?
Glass kiln with high quality silica brick with silicon oxide content, low melt index, mainly used for glass kiln crown, parapet, wall hanging, small furnace arch superstructure and regenerator.
Q: Which material is good for furnace refractory?
Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.
Q: Why is the three oxidation of two silicon is very harmful impurities in silica brick
Heating calcination is the best way to extend this sort of impurity removal. Remove impurities
Q: Can not use it two brick
Acidic silica brick refractory material, has good ability in acid slag erosion
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: Physical solid waste disposal
Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products when firing, reduce cracks, improve the rate of finished products.
