$Fused Silica Refractory Bricks$

Q: Because of the recent relates to this industry, by way of learning to name for all raw materials, I hope knowledgeable friends exhibitions, thank you.: Classification of chemical components of refractory materialsAccording to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.

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: The provisions of the brick classification, technical requirements, test methods,

Q: The brick is mainly used in the place?: Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.

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 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: 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 chemical composition of silica brick and its physicochemical index?: The physicochemical index of silica brick:Turn left to |

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
