- 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?
- Lightweight materials have uniform internal structure, high compressive strength, corrosion resistance, heat shock resistance, oxidation resistance, high temperature and low thermal conductivity. Dongshin refractories manufacturers manufacturers supply, price is appropriate
- 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?
- 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: What are the high temperature insulation materials?
- If there is atmosphere protection, then graphite is a more powerful material. Melting point 3850 degrees Oh, almost all ultra high temperature kiln, can be protected by atmosphere, all with graphite material.
- 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: 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.
