Low Creep High Alumina Checker CNBM Made in China

Q: Zirconium corundum 25 content and 40 content, how to distinguish in appearance?: Fused zirconia corundum brick is pure alumina and zirconia containing silica 65%, about 34% of the zircon sand in electric furnace melting after internalization into moulds cooling and the formation of the white solid, the petrographic structure by zirconium corundum and plagioclase eutectoid and glass phases, from the phase is eutectoid zirconium corundum and plagioclase phase, glass phase filling between their crystallization.

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 price of concrete self insulation bricks?: If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)

Q: Which is good, glazed brick and whole cast glazed brick?: 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: Wave tile and throwing glaze, tile which good?: The main advantages of all glazed glazed tiles are that they can be very rich and beautiful in texture and pattern, and they are suitable for family decoration, and can choose patterns according to their own family decoration style. Compared to the glazed tile, it has better pollutant discharge performance, and many pollutants are difficult to penetrate into it.

Q: How to improve the induction furnace campaign, from the promotion of refractory life start: According to the use of atmosphere, choose the appropriate spraying materials, such as infrared radiation paint

Q: Is liquid phosphoric acid two aluminum hydrogen flammable?: Two aluminum liquid hydrogen phosphate using spray paint, cement, refractory castable and binder for foundry industry, mainly used in refractory industry corundum, chromium corundum nozzle coal water slurry gasifier with chromium aluminum zirconium corundum brick production.

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 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.

Q: What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?: Casting, casting mouth often appear shrinkage, brick porosity more, the density is lower, so in the brick wall of glass melting, the shrinkage in the kiln direction, if the nozzle outward, when the brick to erosion is very thin, can cause leakage of liquid glass accident. When the flame space is used in the upper part of the bath furnace, the service life is long, and the glass liquid problem can not happen, so the casting mouth is used outwards, and the service life is prolonged.
