- Q: Zirconium corundum 25 content and 40 content, how to distinguish in appearance?
- It is in the production process, zirconium corundum bricks are likely to cause pollution.Fused zirconia corundum brick is also called AZS AZS English is abbreviated to AZS, is based on three chemical composition of Al2O3 - Zr02 - Sio2 phase diagram of three component system, according to the content of the order, Al2O3 A, Zr02 Z, Sio2 S, national standards for the use of this abbreviation, such as No. 33 cast brick, abbreviated as AZS, 33#, No. 36 fused zirconium corundum brick, abbreviated as AZS, 36#, No. 41 fused zirconium corundum brick, abbreviated as AZS - 41#.
- Q: What are the advantages of refractories?
- The castable refractory is a refractory product with a certain shape after being melted at high temperature by a certain method. Neutral refractory is refractory material which is difficult to react with acid or alkaline slag at high temperature, such as carbon refractory and chrome refractory. Some of the high alumina refractories are also attributed to this category.
- Q: Wave tile and throwing glaze, tile which good?
- Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.
- Q: Expansion ratio of lightweight corundum refractory bricks
- Light corundum refractory brick, because of its production methods and the introduction of different additives, there are certain differences in the content of Al2O3, just burn add general light corundum refractory brick and foam and gasification method cannot be made, the content of Al2O3 is generally not more than 99%, with alumina hollow ball manufacturing transfer are corundum brick with high content of Al2O3.
- 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 adopted in each part of the blast furnace?
- The lower part of the shaft due to high temperature and dust by scouring and alkali metal vapor erosion, so the requirements for the slag resistance, alkali resistance and high temperature resistance, wear resistance of high quality clay brick, high alumina brick, carborundum brick or corundum brick. Belly temperature reaches 1400~1600, and slag, steam erosion, erosion and corrosion is strong, therefore, the silicon carbide reaction bonded silicon carbide brick.
- Q: What is the difference between corundum and high alumina?
- The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.
- 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 brick has a strong resistance to glass liquid corrosion!It is better to fuse the furnace with fused zirconia corundum bricks.Fused zirconia corundum brick, regardless of the size of the furnace, the use of small hundreds of kilograms can be used, depending on the design of the kiln!
- Q: What are the main constituents of refractory bricks?
- Corundum refractory brick and corundum brick is a kind of refractory brick with AL2O3 content not less than 90% and corundum as its main phase. It can be divided into sintered corundum bricks and fused corundum bricks.
- Q: What kind of rock is corundum produced?
- If Ti4+ and Fe2+ containing a small amount of blue, a sapphire; containing six symmetrically distributed acicular rutile or other inclusions in some crystals, can produce six star awn, known as star ruby or sapphire stars, are precious stones. Corundum is vitreous luster with no cleavage, but cracks occur because of the presence of poly twin crystals that are often formed by the base or face of a face. Specific gravity 3.98. Of relatively low silicate igneous and metamorphic rocks and common in alluvial deposits. The U.S. state of North Carolina and Georgia, Russia's Ural mountains, South Africa as the main origin of the transvaal.
