Q: Common bond brick?: Lime should contain a lot of active CaO, I decompose CaCO3 and MgCO3 not more than 5%, Al2O3+Fe2O3+SiO2 no more than 5%. When the content of large particles, burned Ca-CO3 and over burned lime, the product produced caves, affecting the quality of products.

Q: Why will expand when heated brick: In the process of SiO2 drying, the four crystalline transformation points of 117, 163, 180~270 and 573 DEG C are found, among which the volume expansion caused by the 180~270 is the largest.

Q: Such purpose and scope please give me detailed points thank you because I am learning stage: Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature. The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass. Tridymite and cristobalite and quartz remaining at low temperature due to phase change, volume changes greatly, so the brick thermal stability at low temperature is very poor. In use, under 800 degrees Celsius, slowly heating and cooling, so as not to produce cracks. The use of temperature in blast furnace so should not be below 800 DEG on. The properties and process of silica crystal with SiO2 transformation is closely related, therefore, the proportion of it is one of the important quality indexes of silica brick. General requirements below 2.38, high quality silica brick should be less than 2.35. The true density is small, reflecting a large number of scale quartz and square quartz in the brick, the residual quartz is small, so the residual line expansion is small, and the strength is decreased in useThe raw materials for the manufacture of silica brick. The higher the SiO2 content of silica raw material, the higher the refractoriness. The most harmful impurities are Al2O3, K2O, Na2O and so on. They seriously reduce the refractoriness of refractory products. Brick with SiO2 content of not less than 96% of silica as raw materials, adding mineralizer (e.g. millscale, lime) and binder (such as molasses, sulfite pulp waste liquid), after mixing, molding, drying, sintering and other processes in the system.

Q: Semisilica brick, clay brick, high alumina brick and what is the difference?: The share of A12O3 and SiO2 is different

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

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: 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: What are the main constituents of refractory bricks?: (a) containing refractory brick brick, refers to more than SiO293%, is the main varieties of acid resistant brick. It is mainly used for coke oven building, also used in furnaces all kinds of glass, ceramic and carbon calciner, refractory brick arches and other load-bearing parts, is also used in high temperature bearing part of hot blast stove, but should not be used in thermal equipment below 600 DEG C and the temperature fluctuation in the.

Q: Brick: The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass. Tridymite and cristobalite and quartz remaining at low temperature due to phase change, volume changes greatly, so the brick thermal stability at low temperature is very poor. In use, under 800 degrees Celsius, slowly heating and cooling, so as not to produce cracks. The use of temperature in blast furnace so should not be below 800 DEG on.

Q: Such purpose and scope please give me detailed points thank you: Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.
