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: Such purpose and scope please give me detailed points thank you because I am learning stage: Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.

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: 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: The high thermal conductivity of silica brick and traditional brick what is the difference?: Brick, high thermal conductivity has been greatly improved in terms of morphology, crystal structure, physicochemical index. The structure and morphology of high thermal conductivity of silica brick,Structure and morphology of high thermal conductivity and the traditional brick brick magnified 20 times were compared, high thermal conductivity silica pore size distribution is more uniform and finer.

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: Common bond brick?: Lime should contain a lot of active CaO, I decompose CaCO3 and MgCO3 not more than 5%, Al2O3+Fe2O3+SiO2 no more than 5%. When the content of large particles, burned Ca-CO3 and over burned lime, the product produced caves, affecting the quality of products.

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: High temperature refractory material?: Special materials often use AZS brick (i.e. corundum brick), corundum brick, magnesia chrome bricks, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Insulation refractories are often used diatomite products, asbestos products, insulation board. Unshaped refractories are often used refractory castable, refractory clay, refractory ramming material, refractory plastic and fettling material, fire resistance, gunning, refractory cast material, fireproof coating, lightweight refractory castable, gun mud.

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.
