Q: How much is the silica powder in refractory bricks.: It's not easy to construct, also need to consider the technical and economic indexes, DH3, 1 kg silica powder replaces 1 ~ 3 kg cement, which is the reason why silicon powder was not used and spreaded in concrete in past, choose some silica power fume. In general, with the smoke escaping by special capture device for collecting and processing To determine the mixing method of silica powder, when mixing silica powder, you should find out the optimal dosage in order to obtain the best results, as the study, the content is 5% ~ 30%, H, the mixing of super high strength concrete, use same amount of silicon powder to replace equal cement to main same fluidity, Microsilica or Silica Fume, it is mainly according to the design requirements, and does not reduce the amount of cement, sand and stone to adjust the optimal dosage of water reducer, when deciding the best mixing amount of silica fume, the concrete is too sticky, most use naphthalene water reducing agent.

Q: Where the refractory bricks rider bricks that are used for building arch and vault should be put?: Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.

Q: What are the ingredients of brick?: Is the most traditional brick masonry material, its composition is clay as the main raw material gradually to the development of industrial waste utilization of coal gangue and fly ash, and by solid and hollow porous to development, development by sintering to non sintering.

Q: Can red bricks be burned in tunnel kiln which used to burn refractory brick?: The raw material determines the production process; the output determines the kiln type; the technology determines the quality and quantity.

Q: Are refractory bricks poisonous?: Zirconium minerals are often associated with other minerals in the mining, because the bricks are basically burned under more than 1 thousand degree. But some of the bricks contain heavy metal elements chromium. Some of the brick contains zirconium, the vast majority are very safe, and heavy metal elements have a certain toxicity, there are many kinds of refractory bricks that the nature is very stable, and the associated minerals are generally radioactive

Q: what kind of refractory brick is suitable for 1300 degrees converter?: High alumina bricks of above 3 grade, containing more than 60% aluminum

Q: What are the properties of clay bricks?: The clay brick belongs to weak acid refractory. Because of the fluctuation of chemical composition, the production method is different, and the difference of sintering temperature makes the properties of clay brick change greatly. Ordinary clay bricks are divided into (NZ) 1, 40, (NZ) 1, 35, (NZ) 1, 30, three trademarks on the basis of the amount of Al2O3 content in the components.
