- 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: How long is the duration of fire resistance of hollow glass magnesium board
- Glass magnesium board is non-combustible board with excellent fire resistance ability, the continuous burning time of flame is 0, non-combustible at 800℃, no flame at 1200℃, achieving the highest level of fire retardant level A1; Partition System cooperated with high-quality keel can endure fire for more than 3 hours. In the process of combustion, a large amount of heat energy can be absorbed, and the temperature of the surrounding environment will be delayed.
- Q: Which industry does refractory belong to?
- It belongs to inorganic refractory: Ceramic refractory bricks (used in steel-making furnaces) There is also organic polymer in heavy industry: Halogen-containing and halogen-free It belongs to construction industry.
- Q: What a blast furnace refractories generally?
- Usually metal anchorage plus wear-resistant refractory spray paint. at the middle part we use high alumina bricks, corundum bricks. high duty refractory is important in improving bosh furnace lining.
- Q: Where is the sizing nozzle for refractories? Just enter the line, master into!
- Refractories in this industry, Luoyang Hua Heng is the first to bear, and their services are thoughtful, and the quality is still very good!Wish you success！
- Q: Does anyone know what is a lightweight refractory material?
- Light weighted castable is one of the kind.
- Q: What's the frequently used refractory material?
- What's the frequently used refractory material in the market? It is usually classified into four categories: Common Refractory: silica?brick, semi-silica brick, refractory fireclay block, high alumina refractory brick, magnesia brick, etc. Unshaped Refractory: repairing?mass, ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, sling refractory, refractory coating, lightweight refractory?castables, stemming, etc. Special Refractory: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia, etc. Fireclay Insulating Refractory: diatomite product, asbestos product, insulation?board, etc.
- Q: Does anyone know the fire endurance of steel stud partition?
- The fire endurance degree is 1 hour. which is in line with the national building material fireproofing test standards. CaSo4.2H2O is molecular gypsum molecular structure formula, containing 20% ??water, crystal water and free water, when putting on fire, 10% of the surface water will slowly evaporate, remaining10% of crystal water. It is a class A fire retardant material itself. The longest time can be 4 hours.
- Q: On the problem of making refractory materials
- But if only a is chosen, does it mean that as long as it is insoluble in water, it can be made of refractory material? Obviously absurd!
- Q: Who knows what material is in the center of fireproof rolling curtain?
- In fact, in general, the middle of fire roller shutter is fire prevention materials, filled with asbestos fire protection materials in the fire shutter door of the two layer of iron sheet. I hope my answer can help you
