- Q: What are the materials of insulation firebricks?
- The raw materials of firebricks, firebricks have various raw materials, and the composition of which can be divided into six categories: soil, stone, sand, mineral, powder and others. One of the raw materials, soil: bauxite, kaoline, clay, diatomite Another raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, and silica Another raw material, sand: clay sand, zircon sand, quartz sand, and magnesite Another raw materials, mineral: chromium mineral Another raw material, powder: aluminum powder, micro-silica powder, and silicon powder Another raw materials, others: asphalt, graphite, phenolic resin, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica sol, boron carbide, calcium aluminate cement, nitride material, haydite, aluminum oxide, alumina sol and zirconia, etc.
- Q: who knows the fire resistant levels of fireproofing glass?
- Fireproofing glass is a kind of special glass which can keep its integrity and thermal insulation performance in regular insulating refractory trials. and it can be divided into three classes according to its fire resistance: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements. Classify from the structure,fireproofing glass can be divided into composite fireproofing glass and monolithic fireproofing glass.
- Q: Who knows the refractoriness of high temperature lightweight firebricks?
- pores of high temperature lightweight refractory bricks is made by lightweight aggregate such as combustibles, foaming?agent, and hollow?sphere production with better thermodynamic stability. Refractoriness reaching 1200 ℃ or more is first grade refractories. fire resistance of building blocks of 100mm thick can reach 225 minutes, 200mm thick brick 480 minutes.
- Q: How about the prospect of refractory material?
- Due to the rise of raw material, the prospect is not good with inflation, lower prices and decreased profits. The product requirements have been enhanced and there is vicious competition. Therefore, it is really bad.
- Q: Is refractory material harmful to human body?
- Part is harmful to human body, mainly refractory raw material, silica powder inhalation can cause lung tuberculosis, siliceous fiber on the human body does have great harm, in fact, like other inorganic fiber in the inhalation of the trachea or lung after the same harm to human
- Q: What are the applications of refractory?
- Refractory usually refers to the inorganic non-metallic material, whose refractoriness is above 1580℃. And it can be used for necessary parts. You can search more information on the Internet. It can be used in ferrous metal metallurgy, chemical, ceramics and so on. Fire material generally refers to above 1580 ℃ refractoriness of inorganic material, where the material can be used in corrosion, the network is very strong look, we know that colored when the metallurgical, chemical-resistant ceramics, etc. of industrial production high temperature. Different things are needed in different industries.
- Q: What kind of refractory materials are used in metallurgy industry?
- Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.
- Q: Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
- The fire-resistant differences of B1- and B2-level extruded insulation boards are as follow: B1-level materials will be smothered as soon as staying away from fire, namely, they will be extinguished after leaving fire, or be put out in 10 seconds. B2-level materials will be in low-grade combustion, namely, the fire will not get wilder, and drippings will not ignite the filter paper. I hope my answer can help you!
- Q: I wanna ask what are the acidic refractories?
- You can look at these: (1) silica?brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity. I hope it is useful!
- Q: what textures of furnace refractories are good?
- The common one uses the ordinary aluminous fireclay brick and GB / T 3994-2005 insulating fireclay brick. The ones with excellet texture are high-grade thermal insulation refractory brick and GB / T 3995-2006 high alumina insulating firebrick, whose model is A13, the texture is alumina, A13 50u, advanced heat insulating brick B5; intermediate heat insulating brick B2, and so on. Dolomite brick: The formation of coating is of good performance and corrosion resistance, but to some extent, there exsits the f-CaO in the brick, which is easy to hydrate, and hard to transport and storage, thus less using in the production. Magnesia-chrome brick: The formation of coating is good, so it is widely used for burning zone, but the disadvantage is poor thermal shock resistance, coupled with the highly toxic positive Hexavalent Cr, so the international countries that produce and use the magnesia-chrome bricks are gradually reducing. The production unit using this brick now, please find alternatives as soon as possible.
