$Hot Blast Furnace Coke Oven Refractory Silica Brick$

Q: The hot blast stove when the temperature did not rise against the brick interface decreased: Insulation of hot blast stove, key insulation silica brick hot stove, hot blast stove is shutdown or need repairing in blast furnace.

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: 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 introduction of silica brick: The characteristics of silica brick: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.The use of silica brick:Mainly used for masonry brick oven carbonization chamber, a combustion chamber and a partition wall, glass furnace and kiln roof, pool wall, high temperature hot blast furnace, glass furnace, load-bearing pool wall, hot blast stove, baking furnace of carbon bearing part of high temperature furnaces etc.. Rongsheng with refractory

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: 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: Can iron oxide be used as refractory material?: Iron oxide can not be used as refractory material, but it can be used as refractory additive. Iron oxide can be used as pigment

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: 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.
