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: The introduction of silica brick: Brick refers to the content of more than 93% products SiO2. Brick with SiO2 content of not less than 96% of silica as raw materials, adding mineralizer and binder, through mixing, molding, drying, sintering and other processes in the system. The higher the content of SiO2 in silica raw material, the higher the refractoriness of the product. According to the use of brick varieties, divided into: coke oven silica brick, brick for hot blast stove, electric stove with brick, brick for glass furnaces. According to the transformation is divided into: standard bricks, tiles, bricks and general special brick etc..

Q: Why is the new trend of the high thermal conductivity of silica brick: The high thermal conductivity of silica brick all inherits the advantages of traditional coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity.

Q: Such purpose and scope please give me detailed points thank you because I am learning stage: 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.

Q: The brick is mainly used in the place?: Partitions used in coking and combustion chambers for coke ovens

Q: The United States of our brick anti-dumping duties?: At present of our brick anti-dumping rate is 73.10%

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: Can not use it two brick: The softening temperature is up to 1640~1670 DEG C, and the volume is stable at high temperature for a long time.

Q: How to improve the thermal conductivity of the coke silicabrick rate?: To improve the thermal conductivity of silica brick for coke oven rate method:Manufacture of high density and high thermal conductivity of silica brick, adding additives such as CuO, Cu2O, TiO2, Fe2O3, (FeO), can improve the thermal conductivity of silica brick.

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.
