Description:

Silicate 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

 

Advantage:

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

Acid Resistant  Silicate Bricks for Chimneys

Acid Resistant  Silicate Bricks for Chimneys


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 will expand when heated brick
After high temperature after the formation of tridymite and cristobalite and quartz and a small amount of residual glass phase, quartz heating to 220-240 DEG C, in a certain degree of thermal expansion, brick maximum expansion occurs in 100~300 DEG C, 300 expansion before the total amount of expansion is about 70%~75%.
Q: The specific content is what gb/t2608-2012 brick
Quality assessment procedures, packaging, marking, transport, storage, and quality certificates. Suitable for siliceous refractory bricks.
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: 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: What are the main constituents of refractory bricks?
(a) containing refractory brick brick, refers to more than SiO293%, is the main varieties of acid resistant brick. It is mainly used for coke oven building, also used in furnaces all kinds of glass, ceramic and carbon calciner, refractory brick arches and other load-bearing parts, is also used in high temperature bearing part of hot blast stove, but should not be used in thermal equipment below 600 DEG C and the temperature fluctuation in the.
Q: 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: What is the silica refractory products?
High silicon content in high temperature expansion sintering temperature between 1390-1410 in furnace arch
Q: The formula in the refractory brick, and firing curve, who knows?
Iron scale powder 0.45-0.55%, cement 0.9-1.1%, lime milk 6.5-7.5%, pulp 1.95-2.2%, the silica powder, perlite will be added to the wet mill in proportion, and then add iron scale powder, cement, dry roller 1-2 minutes later
Q: Such purpose and scope please give me detailed points thank you
Mainly used for coke oven carbonization chamber and the combustion chamber wall, open hearth furnace regenerator and a sediment chamber, soaking furnace, glass furnace, refractory materials and ceramic brick kiln, kiln vault and other load-bearing parts. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
