- 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?
- 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
- Iron oxide can not be used as refractory,
- 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?
- 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?
- 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?
- The mineral composition of high alumina refractory brick and high alumina refractory brick is corundum, mullite and glass phase. The raw materials are high alumina and sillimanite natural ore. They are also made of fused alumina, sintered alumina, synthetic mullite and calcined alumina in different proportions with clay. It is produced by sintering process. But the products are casting brick, brick, brick fused grain and unshaped refractory brick. High alumina refractory brick is widely used in iron and steel industry, non-ferrous metal industry and other industries.
