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

Refractory Silica Bricks Used in Hot Blast Furnace

Refractory Silica Bricks Used in Hot Blast Furnace


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.
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
Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.
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: Semisilica brick interpretation
High temperature volume stability. Volume change is small.
Q: Glass kiln brick for physical and chemical indicators?
Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.
Q: The brick is mainly used in the place?
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.
Q: Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450
Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.
Q: The chemical composition of silica brick and its physicochemical index?
Brick refers to the refractory products in more than 93% of the content of SiO2
Q: What is the silica refractory products?
High silicon content in high temperature expansion sintering temperature between 1390-1410 in furnace arch
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.
