Q:About the use of horseshoe glass kiln refractories
the lower portion of advanced clay brick, the lower portion of magnesia-chrome brick arch - high-purity silica brick; flue - clay brick; breast wall--33 # fused zirconia corundum brick (with shrinkage); fused zirconia bottom --33 # fused zirconia corundum brick (with shrinkage); regenerative chamber- the upper part of sintered magnesia-chrome brick, cooling section 33 # electric smelting no shrinkage fused zirconia corundum brick; the wall - the melting section 41 # no shrinkage fused zirconia corundum brick (including 41% of zirconium; the lattice- superstructure of high purity magnesia brick, the same below); small stove --33 # fused zirconia corundum brick (with shrinkage). It can be said that it is the maximum configuration, if the funds is limited it can be downshift appropriately.
Q:What is acid refractory material?
Corundum products containing more than 95% of alumina are a kind of high quality refractory materials with a wide range of uses. Chrome brick by using chromium oxide as the main component of the corrosion resistance of steel slag is good, but the poor heat shock resistance, high load low deformation temperature. Carbon refractories with carbon bricks, graphite and silicon carbide products, low coefficient of thermal expansion, high thermal conductivity, heat vibration performance, high strength, corrosion resistance to acid and salt, without wetting of the metal and slag, light. It is widely used as lining material of high temperature, and also used as lining of autoclave in petroleum and chemical industry. Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment. High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.
Q:Which refractory is suitable for the tunnel kiln?
The refractories produced by the following ten manufacturers are relatively good. They are all being the top ten brands! 1. king coconut (Chinese well-known trademarks, famous brand, the nation's largest manufacturer of wood panels, large building materials chain enterprises, Hangzhou king coconut Holding Group Co., Ltd.) 2. Fuxiang (founded in 1998, the leading professional sheet production outstanding enterprises, Fuxiang Industrial Co., Ltd.) 3. Bunny (China famous brand, China Top brand, plywood industry iconic brand, large listed companies, high-tech enterprises, Edward Bunny decoration materials Co., Ltd. 4. new Millennium boat ( Chinese well-known trademarks, famous trademarks in Zhejiang, Zhejiang famous brand, well-known trademarks in Hangzhou, Zhejiang Province key forestry enterprises, the Millennium boat Group Hangzhou Huahai Wood Industry Co., Ltd.) 5. Jin Luli (China famous brand, Chinese brand-name products, Shandong Province, to wood-based panels and steel-based enterprises, hundred private enterprises in Shandong Province, Luli Group Co., Ltd.) 6. Albert (professional fire protection board development / production and marketing of the modern manufacturer, the introduction of advanced production technology industry HPL) 7. desert oasis (China famous brand lumber, China's top ten brands plate, sheet famous Chinese brand, oasis Wood) 8. Peng Che-hung (professional fire protection board development / production and marketing of the modern manufacturer, the introduction of advanced production technology industry HPL ) 9.

Mogan (national key high-tech enterprises, China's largest and most influential environment-friendly decorative materials production one of the enterprises, Zhejiang Hua Yunfeng new material Co., Ltd.)
Q:Who knows how many poured refactory material are there?
Casting refractory material, refractory material used often are AZS brick, corundum brick, direct bonding magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide brick, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide and other refractory materials.
Q:Is there anyone who can explain how to grade the level of fire insulation board?
The classification of fire proof level for thermal insulating material 1, Burning performance of building material can be classified into the following several grade according to national standard GB8624-97: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect.
Q:What is the criterion of entry of refractory clay industry?
Chemical composition of refractory clay is one of the important factors affecting its quality. Al2O3 is the beneficial part of refractory clay, and it mainly exists in aluminum hydroxide minerals (diaspore, boehmite, gibbsite), and it also exists in aluminosilicate minerals (kaolinite, illite montmorillonite, etc.). In general, the content of Al2O3 in soft and semi-soft clay is 30% to 45%, the hard clay is 35% to 50%, and high alumina clay 55% to 70%. Fe2O3 mainly exists in hematite, magnetite, goethite and siderite, and is the main harmful component of refractory clay. There is no evident law on the content of Fe2O3. The content in high alumina clay is 0.5% to 2.2%, hard clay is 0.5% to 2.5%, and the soft clay is generally 1.0% to 2.5%. K2O and Na2O are harmful impurities in refractory clay, which mainly exist in illite and mica and other minerals, and the content varies greatly. CaO and MgO, etc., although they are harmful impurities, but the content is generally small.
Q:What are the disadvantages of the refractory industry?
The rapid development of continuous casting technology allows Hua Heng refractories to be improved in variety and quality. The development of refractory for continuous casting has a significant impact on the production of continuous casting and quality of continuous casting billet. Constructing and putting Baosteel into action has greatly pushed the improvement of the refractory technology. Continuous casting refractory is an important part of the continuous casting machine. In addition to the general characteristics of refractories, it is also required functions that can purify molten steel, improve the quality of steel, stabilize temperature and composition of the molten steel, control and regulate the molten steel flow. Therefore, it is known as functional refractories. Continuous casting Refractories include: (1) ladle refractory - ladle lining, permanent lining and ventilation components; (2) tundish refractories - permanent lining, coating, insulating plates, clad etc; (3 ) functional refractories - long nozzle for non-oxidizing casting, submerged nozzle, monolithic stopper, sliding gate; (4) ceramic purifier for purifying molten , slag dam, alkaline paint and horizontal separating ring and gate board for continuous casting.
Q:What is the difference in the nature between the refractory material and thermal insulation material
thermal insulation material is used to thermal insulation and the transfer of heat insulation. refractory material is defined as greater than 1580 ° non-metallic materials, such as calcium silicate board. its using temperature can reach to 1100 degrees, and some can also be used at high temperatures, and all high-temperature industrial can't be oprated without it, and the using temperature of polycrystalline alumina fibers can reach to 1800 degrees
Q:how to classify the fireproofing material levels A1 A2 B1?
their classification is shown specifically in Fireproof  Specification of Building Interior Decoration Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
Q:What are the fire resistances of grc partition panels?
Light partition walls with keels has the longest fire resistance of 4 hours according to the thickness of the walls.
