Low Creep High Alumina Checker CNBM Made in China

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 material is used in an iron smelting furnace?: In fact, refractory refractory ah is special ceramic frequently used 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.

Q: What are the advantages of refractories?: Aluminosilicate refractory refractory material refers to SiO2-Al2O3 as the main ingredient, according to how much the Al2O3 content can be divided into semi silica (Al2O3 15~30%), clay (Al2O3 30~48%), high alumina (Al2O3 > 48%) three.

Q: What is the price of concrete self insulation bricks?: Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.

Q: What does refractory consist of?: According 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: What's the jade stove for?: Corundum furnace for corundum smelting furnace, usually electric arc furnace for smelting dense corundum, corundum, white corundum, zirconia corundum, magnesia, magnesium aluminum spinel and fused refractory materials, professional design, Xi'an Xinda furnace engineering limited liability company manufacturing corundum furnace.

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: Is liquid phosphoric acid two aluminum hydrogen flammable?: Liquid phosphoric acid two hydrogen aluminum features: easy mixing, molding, especially suitable for field construction, so liquid phosphoric acid two hydrogen aluminum is not flammable

Q: How do corundum bricks bind?: Each refractory brick is provided with corresponding refractory mud, and corundum bricks are bonded with corundum mud.

Q: What can zirconium sponge do for those industries?: Uses: aerospace, military, nuclear reactions, atomic energy, and metal superhard materials, the manufacture of bulletproof alloy steel, can also be used in the reactor uranium fuel coating alloy; zirconium at high temperatures easy to launch electronicProduct characteristics: zirconium metal has very strong corrosion resistance, ultra high hardness and strength
