- Q: What are the advantages of refractories?
- Special refractories are new inorganic non-metallic materials developed on the basis of traditional ceramics and refractory materials. For example, AZS brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on
- Q: What is the blast furnace ceramic cup called by the refractory factory?
- In fact, a kind of ceramic cup of blast furnace refractories, application in blast furnace bottom and hearth contact steel lining using a layer of non carbon refractory materials, such as Theron with corundum brick, corundum mullite and synthetic mullite bricks etc..
- Q: Wave tile and throwing glaze, tile which good?
- These two tiles have their respective advantages and disadvantages, in fact, to say which kind of good, mainly depends on the decoration of personal preferences and the location of the shop. If it is only the shop wall, then design and pattern rich whole glazed tile is good, it can make the room impressive, improve decorative effect, make the decoration style to fit the characteristics of his personality. In addition, clean up is relatively easy, not easy to contaminated with oil stains and other pollutants. If it is laying floor tiles, tile Douglas suggested the use of tiles, tiles of good antiskid effect, water absorption rate is relatively low, so the kitchen toilet bathroom and other wet places is not easy to water seepage, improve the convenience of life.
- Q: How to improve the induction furnace campaign, from the promotion of refractory life start
- According to the workpiece, choose the appropriate hardware castable, corundum brick or refractory bricks, etc.
- Q: What refractory materials are used in industrial furnaces?
- Economically, it is necessary to do technical and economic analysis when selecting materials reasonably. Under the premise that the technical indexes agree with the working conditions of the furnace, the refractory materials with low quoted price should be used as much as possible, without high-grade finished products. To think about whether to make self (such as irrigation, refractory concrete) as far as possible to repair old.
- Q: What is the difference between corundum and high alumina?
- The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.The difference between them lies in the content of alumina and the alumina refractory products with alumina content higher than 48%The content of Al2O3 is higher than 90%, which is called corundum brick.
- Q: What's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?
- Fused zirconia corundum refractory material of glass fiber kiln quantity is little, generally used in the kiln feed arch furnace flue, where large amount of places are currently using dense zirconium Zr, dense chromium
- Q: What kind of refractory material will be used in the glass kiln?
- High temperature & glass corrosion performance of the brick is slightly lower than that of chromium oxide, also by isostatic pressing forming method, its technical indicators ZrO2>65%, <2.0% porosity, volume density of about 4.25g/cm3, the temperature in E glass is higher than 1370 DEG C have erosion. Used in the E glass melting pool unit kiln glass temperature slightly lower at the end of the transition path, forming the bottom of the pool and forming path path flow tank and bushing support brick etc.. In addition, the dense zirconia brick is used as the backing brick of the dense chrome brick.
- Q: Ask for help about the phase of refractory material
- Secondary crystalline phase. The second phase and second phase or second phase, and the main crystal phase and is in high temperature liquid phase coexistence in refractory material, the number and influence on high temperature properties of materials is the main crystal phase is small second phases. As to the main crystalline phase of periclase magnesia chrome brick, magnesia brick, magnesia brick and magnesia calcium brick respectively containing Cr spinel, spinel, forsterite and calcium silicate two are secondary phase. There are structure of refractory refractory material in the crystal phase, especially the direct combination of high melting point and so on, the resistance to high temperature also tend to benefit. Compared with the ordinary brick, the second phase of the refractory products, make the products refractoriness under load are improved. Many according to mineral composition of refractory material named, such as mullite corundum brick, corundum mullite brick, is its main crystal phase and the second phase composite named. The former is mainly crystal phase, the latter is sub crystalline phase.
- Q: What kind of rock is corundum produced?
- Aluminum oxide (Al2O3) mineral. Due to Mohs hardness of up to 9, mainly used as high-grade abrasives. The crystal belongs to the three party system, a dolioform six square column, some are needle or plate. Aggregates are massive or columnar. Usually white, gray, yellow and other colors. If a small amount of Cr3+ is red, a ruby is called;
