- 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
- How to keep the brick masonry temperature not lower than 600 DEG C, while the exhaust temperature is not higher than 400 DEG C.
- 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 acid refractory?
- Refractory materials are mainly quartz glass products, combined with fused quartz products, silica brick and unshaped refractories. Semi siliceous refractory materials are generally attributed to this category. As for fireclay refractories, they are also classified as semi acidic or weakly acidic refractories. Also, zircon refractory and silicon carbide refractory for special acidic refractory materials are also classified into this category.
- Q: What role does silica play in refractories?
- Low fractory refers to the alumina content between 10%~30%, SiO2 content is less than 85%, semisilica brick SiO2 = 65%,The SiO2 content of not less than 93%, refractory material to natural quartz rock as the main raw materials are called silica, silica brick, silica brick, quartz glass and special products. China's literature generally put this type of product is called "siliceous refractory products", which is the most important brick.
- 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: 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 chemical composition of silica brick and its physicochemical index?
- Brick refers to the refractory products in more than 93% of the content of SiO2
- Q: Why in the production of the brick to detect the volume density
- Density is the property of material, different density of materials, density of the same kind of material is not up to standard, affecting performance.
- Q: The formula in the refractory brick, and firing curve, who knows?
- Iron scale powder 0.45-0.55%, cement 0.9-1.1%, lime milk 6.5-7.5%, pulp 1.95-2.2%, the silica powder, perlite will be added to the wet mill in proportion, and then add iron scale powder, cement, dry roller 1-2 minutes later
