- Q: Physical solid waste disposal
- Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
- 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: The hot blast stove when the temperature did not rise against the brick interface decreased
- Different insulation methods can be adopted according to the length of the stop time and the location and equipment of the overhaul. Gold, refractory material factory specializing in the production of various specifications of brick
- Q: Why will expand when heated brick
- After high temperature after the formation of tridymite and cristobalite and quartz and a small amount of residual glass phase, quartz heating to 220-240 DEG C, in a certain degree of thermal expansion, brick maximum expansion occurs in 100~300 DEG C, 300 expansion before the total amount of expansion is about 70%~75%.
- 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
- The main damage of silicon carbide side wall brick is stress damage, not chemical erosion. Chemical damage is formed prior to the formation of the groove, and the damage to the chemical erosion is little after the formation of the groove.
- Q: Why is the new trend of the high thermal conductivity of silica brick
- The use of high thermal conductivity of silica brick, reducing coke fuel consumption, reduce emissions of pollutants such as NOx, with considerable economic benefits and social benefits, is the future direction of the new technology of using coke oven refractory.
- 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: What role does silica play in refractories?
- The production of clay brick refractory clay raw material is natural, its main mineral is kaolinite (formula Al2O3 - 2SiO2 - 2H2O), clay brick containing SiO2 in 45% ~ 65%, belongs to the weak acid refractory materials, have a certain ability to resist acid slag, but easy to be alkaline slag erosion.
- Q: Physical solid waste disposal
- Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
- 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.
