Q: Mullite bricks in alumina alumina is what?: With mullite as main crystalline phase of high alumina refractory products. Mullite bricks containing Al2O3 64%~75%, refractoriness >1790? C, normal temperature compressive strength 70~260MPa, softening the starting point for 1600~1700 degrees. The manufacturing method for casting and sintering process.

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?: 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: 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 use of temperature ceramic fiber long 950-1260 in general, there are many domestic manufacturers do not understand the deceive customers, often in accordance with the classification of temperature to the material sold to customers, such as zirconium ceramic fiber belongs to the 1400 type, but the long-term use temperature of 1260 degrees or less, impossible to maintain 1400 degrees to 1260 degrees, so the equipment in order to use ceramic fiber, high grade can only be used on polycrystalline fiber

Q: What material is good for refractory bricks?: Clay brick is a refractory brick commonly used in blast furnaces, hot blast furnaces, heating furnaces, power boilers, lime kilns, rotary kilns, ceramics and refractory bricks.
