Silica Brick For Coke Oven CMAX-4

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: 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: 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: Semisilica brick interpretation: High temperature volume stability. Volume change is small.

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: Can iron oxide be used as refractory material?: Is widely used in this area. Mentioned refractory material of high school textbooks generally refers to three two aluminum oxide (alumina), alumina is also used as a refractory material, refractory crucible, porcelain, artificial gemstones.

Q: Can not use it two brick: Acidic silica brick refractory material, has good ability in acid slag erosion

Q: Physical solid waste disposal: The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem

Q: The formula in the refractory brick, and firing curve, who knows?: By silica powder, 81-85%, perlite 15-19%, plus the total weight of the main raw materials of the following accessories

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.
