Product Description:

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.


Silica bricks exhibit excellent refractoriness. These bricks performs extremely well under consistently high temperature.

 

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.

3.Different Moulds. Save mould fees for you.


Typical features:

  • Widely used in coke ovens.

  • Used in high temperature sections of the checker chamber in hot blast stoves.

  • Used as low-cost alternative to andalusite and mullite checker bricks in hot blast stoves.

  • High refractoriness, average thermal shock resistance make it suitable in consistant temperature environment.

Q:The high thermal conductivity of silica brick and traditional brick what is the difference?
Tridymite content high thermal conductivity silica brick is 70%, tridymite content of traditional brick is 60%, tridymite content high thermal conductivity of silica brick than tridymite high content of 10% traditional brick,
Q:How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
Mainly depends on the color and density of brick. Another black clay brick and brick with iron oxide formation and how much the size of bricks
Q:The brick is mainly used in the place?
Partitions used in coking and combustion chambers for coke ovens
Q:Common bond brick?
When adding ingredients, the amount of lime added shall be converted to CaO, and the amount of addition varies depending on the product, usually fluctuating at 1.5~2.5%. For example, the production of coke oven silica brick, the dosage of CaO is 2.0~3.0%; the production of electric furnace top brick, the dosage of CaO is 1.4~1.75%.
Q:Why in the production of the brick to detect the volume density
Product quality control of silica brick.
Q:The specific content is what gb/t2608-2012 brick
The provisions of the brick classification, technical requirements, test methods,
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: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:Why will expand when heated brick
Because the production of raw materials are silica brick, brick with SiO2 content of not less than 95% of silica as raw materials, adding mineralizer and binder, through mixing, molding, drying, sintering and other processes in the system
Q:The difference between clay refractory bricks and refractory brick in the application.
Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use, but the anti alkali erosion ability, thermal shock stability is the worst, a scrap. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.
