- Q: What are some of the new refractories and what are their characteristics?
- Refractory common AZS refractories are often used 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, aluminum oxide, beryllium oxide and other refractory materials, Magnesium Oxide
- Q: Why does refractory need to add coarse firstly and then add fine aggregate?
- Binding agent can wrap particles and improve binding effect.
- Q: What a blast furnace refractories generally?
- Common refractories often use silica?brick, semi-silica brick, fireclay brick, high alumina brick, magnesia brick, etc. special materials often used are AZS brick, corundum brick, directly bonded magnesia-chrome brick, carborundum brick, silicon nitride bonded silicon carbide bricks, nitrides, silicides, sulfides, borides, carbides and other non-oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide refractory insulating refractory frequently used. material diatomite products, asbestos products, insulation boards. monolithic refractories have fettling frequently used, refractory ramming mixes, refractory castable, fire-resistant plastic, refractory clay, refractory gunning refractory projection material, refractory coatings, lightweight refractory castable, stemming etc.
- Q: What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
- there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
- Q: How long is the fire endurance of the rock wool board?
- The rock wool board takes the basalt as raw material and is processed into artificial inorganic fiber through high temperature melting, which is light in weight, non-combustible, heat absorptive, small in thermal conductivity. The initial development in construction is a common type of application used for industrial buildings, which should be consistent with the requirements of "building insulation application categories and basic requirements" . In June 1981 the pre-launch succeeds. The rock wool board is a new type of insulation, burning compartment and sound-absorbing material. Generally the fire resistance of the rock wool board is 140-180 degree within two hours, It is best not to exceed this safe period, in order to avoid security risks.
- Q: What kind of refractories do the anode baking furnace use?
- 5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.
- Q: It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?
- The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic
- Q: What are grades of refractory materials?
- Refractories have lots of varieties which all have different purposes. It is necessary to classify refractories scientifically in order to scientifically study, choose and manage them. Classification methods of refractories include chemical properties classification, chemical composition of mineral classification, manufacturing technique classification, morphology of the material classification. 1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ - 1770 ℃, advanced refractories: 1770 ℃ - 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler, (ratio) Max: Min < 4: 1; Shaped ones: no more than two-entrant, (ratio) Max: Min < 6: 1 or having a acute angle of 50 - 70 °; The specific type :( ratio) Max: Min < 8: 1 or having no more than 4-entrants or having an acute angle of 30 - 50 °; and Special products: crucible, containers and tubes. 3, divided according to the method of manufacturing: burned products, non-burned products and unshaped refractories 4. divided according to the chemical properties: acidic refractory materials, neutral refractory materials and basic refractory materials.
- Q: What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
- 04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
- 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.
