- Q:What kind of refractory material is used in the hearth of reverberatory furnace?
- The alumina fiber has a maximum resistance of 1700 degrees, and the zirconium fiber is generally 1700 to 2200 degrees
- Q:2000 degree of high temperature materials, which belong to high temperature insulation materials?
- Magnesium compounds, ceramics, mica, corundum, silicon, graphite, titanium alloy, diamond, tungsten, silicon dioxide, silicon carbide, carbon, copper oxide, iron oxide, iron, manganese, lightweight mullite corundum brick, high aluminum brick lightweight clay brick, alumina hollow ball1) rock wool board: thermal conductivity 0.041-0.045, fire retardant, fire resistance, temperature absorption, insulation effect is poor.(2) glass wool: construction is simple, free cutting. Antibacterial, mildew proof, aging resistance, corrosion resistance, and guarantee the healthy environment. Low hygroscopicity and stable physical properties.
- Q:Mullite bricks in alumina alumina is what?
- Mullite (3Al2O3 - 2SiO2) high alumina refractory materials as the main crystal phase. The general alumina content in 65% ~ 75%. In addition to mineral composition of mullite, alumina containing low also contain a small amount of glass phase and cristobalite; alumina containing high also contain a small amount of corundum.
- Q:What are the high temperature insulation materials?
- Followed by a variety of lightweight bricks, alumina hollow ball, lightweight brick is relatively high temperature, about 1600 degrees. The others are low.Then there's the heavy brick. Heavy alumina brick, corundum mullite, can withstand 1750 degrees -1800 degrees. Mullite, cordierite lower lows.
- Q:What are the properties of corundum mullite?
- Heavy material has good compactness, high compressive strength, resistance to various corrosive gases, good thermal shock resistance, good thermal conductivity and wear resistance.
- Q:Corrosion mechanism of iron on refractory materials
- Iron oxide can not be used as refractory,
- Q:What material is heat insulated and not afraid of fire?
- According to the different raw materials are divided into rock wool and slag cotton. In 1840, the United Kingdom to achieve the melting of slag after the formation of fibers, produced slag cotton, used for building insulation, so far more than 160 years of history. Features are: thermal insulation performance, also has the fire characteristics, good sound absorption and vibration damping effect, but different materials of mineral wool class containing asphalt, glue or other organic material, easy to produce harmful substances and environmental pollution, low intensity, as the maintenance of the structure of the thermal insulation layer is easy to collapse, the production process is more complicated has been replaced by other materials.
- Q:Which is faster for heat transfer between corundum bricks and high alumina bricks?
- 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
- Q:What material is good for refractory bricks?
- Is the main varieties of acidic silica brick, refractory brick. It is mainly used for coke oven building, also used in furnaces all kinds of glass, ceramic and carbon calciner, refractory brick arches and other load-bearing parts, is also used in high temperature bearing part of hot blast stove, but should not be used in thermal equipment below 600 DEG C and the temperature fluctuation in the.
