Q:Is fireclay corrosive?
No. All of the refractory materials have stable chemical properties and their usability can be guaranteed under high temperatures.
Q:The structure of refractory material
Q:How long is the fire endurance of the rock wool board?
When the average temperature reaches 140 degrees Celsius or 180 degrees Celsius, it starts to lose the fire insulation function.
Q:What are the requirements of refractory temperature of refractory brick?
Oxygen fluctuation of load once happened during operation. Sometimes oxygen control valve will cause oxygen fluctuation of load, and sometimes large particles will block valve of high pressure coal slurry pump. The sudden drop in flow of coal slurry may cause relative excess of oxygen. Oxygen fluctuations directly cause fluctuations in furnace temperature. The range of oxygen fluctuations is 500m³-600m³. The maximum can reach about 1000m³. A sudden increase in oxygen causes a sudden increase in furnace temperature, which will suddenly burn out high-temperature thermocouple. The situation has a great influence on refractory brick and should be avoided. Furnace temperature is very inportant to life of lining of refractory bricks, so it should be strictly controlled not to overheat. There is a cinder layer on the surface of refractory bricks under the condition of normal production. In fact, cinder layer is dynamic. If the temperature is low, cinder layer is thick. If the temperature is high, cinder layer is thin. Appropriate cinder layer may slow the scour of high temperature gas and molten slag. The requirement of refractory brick is higher than that of stoves which use heavy oil as raw material. The main reason is permeability and corrosion of molten slag to refractory material. When replacing refractory bricks, it is found that penetration thickness is 10mm-20mm. After slag penetrates, strength decreases significantly. If temperature is high, erosion intensifies. According to the relevant information, when the operating temperature exceeds 1400 ℃, etching effect multiplies.
Q:What are the requirements of the performances of brasque refractory?
The requirements of the performances of brasque refractory: 1, should have sufficient refractoriness and softening point under a fixed load. Because under the action of the electric arc, the inner and surface temperature of the different parts of the brasque can be up to 1500 ~ 1800 ℃. 2, should have strong slag resistance. Because the inward permeation of slag and smoke at high temperature through its pores of brasque cause melting loss of refractories, organization delamination and flaking. 3, should have good thermal shock resistance. Because in the steelmaking process, opening the furnace door, lifting the furnace lid will cause sudden temperature change of brasque refractory,flaking and cracking, resulting in premature failure of brasque. 4, should have sufficient strength, because the brasque will be impacted at the time of loading, vibrated when tilting, flushed by metal, slag and gas flow when boiling. 5, the thermal conductivity and the conductivity should be small. Refractories commonly used for electric furnace include magnesia bricks, dolomite brick, high-alumina refractory bricks, silicious refractory brick and magnesite ramming material. Due to the different working environment of each parts of the furnace, refractories are different.
Q:What is the magnesium carbon refractory?
The composition of refractory brick There are many types of raw materials of refractory brick, mainly divided into six categories: Soil, stone, sand, mineral, power and others. The first kind of raw material, soil: Aluminum soil, kaolin, clay, diatomaceous earth The second kind of raw material, Stone: Fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, silica The third kind of raw material, sand: Pottery, zircon sand, quartz sand, magnesite The fourth kind of raw material, ore: Chrome ore The fifth kind of raw material, powder: Aluminum powder, silica powder, silicon powder The sixth kind of raw material of refractory brick, others: Asphalt, graphite, phenolic resins, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica solution, boron carbide, calcium aluminate cement, nitride material, shale ceramisite, alumina, alumina sol and zirconia, etc.
Q:I want to consult the fire resistant level standards of external wall thermal insulation materials.
1, The thermal insulation material that has level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2, The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3, Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See article 4.3.6 in the 2009 edition construction technical measures. Level A insulation material is just for fire protection, so its thermal insulation performance is worse than the organic XPS or EPS materials. Hope this will help you.

According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture
Q:how long is the fire endurance of plasterboard?
Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.
Q:What material is refractory material?
Basic refractory materials, basic refractory, CaO, basic, MgO style alkaline earth oxide. The refractory materials mainly refers to magnesia refractories, dolomitic and lime refractory refractory. Main categories: (1) strongly basic magnesite brick, magnesia carbon brick, limestone and dolomite brick refractory materials;(2) alkalescent magnesia chrome refractories, forsterite refractory, magnalium and magnesia-chrome spinel refractory, basic refractory materials, high-temperature caustic slag, alkaline solvent resistance, strongly acidic slag flux or acidic refractory.
