- 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 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
- But you can do refractory additives. Iron oxide paints are widely used in this area. Mentioned refractory material of high school textbooks generally refers to three two aluminum oxide (alumina), alumina is also used as a refractory material, refractory crucible, porcelain, artificial gemstones.
- Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?
- There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color. For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more
- Q: 2000 degree of high temperature materials, which belong to high temperature insulation materials?
- What can withstand 2000 degree high temperature materials on the market? What are the materials belong to high temperature materials? High temperature insulation material the most common are the following: calcium silicate shell, aluminum silicate cotton felt, glass surface, diatomite, vermiculite, foamed cement etc.. Among them, the first three are the most common, especially the aluminum silicate cotton felt, which can withstand 650 degrees of high temperature.
- Q: What material is heat insulated and not afraid of fire?
- Industrial production of perlite as insulation materials began in the United States in 1964Arizona, while China's expanded perlite began production in the late 60s. Expanded perlite includes perlite and pineRock and obsidian (three of which are close to the water content), due to the high temperature in 1000-1300C0, the volume of rapid expansion of 4 - 30 times, so collectively referred to as expanded perlite. Its characteristics are: low thermal conductivity, fire resistance and sound insulation performance is good, non-toxic, cheap, but have very strong water absorption, thermal conductivity due to water is much higher than that of pearlite, water will cause its insulation performance degradation, inorganic porous material, low strength, easy to break; therefore in thermal insulation applications when the need to enhance the hydrophobic and expanded perlite.
- 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 kind of refractory material is used in the hearth of reverberatory furnace?
- 1400 degrees below can use clay brick, high alumina brick; 1400 to 1700 can use mullite bricks, heavy corundum brick; more than 1700 can use zirconia brick, such as zirconia brick
- 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.
