Application of Corundum-Mullite Brick GM81
Corundum Mullite Bricks are mainly used in EAF roof industrial furnace lining, other furnace glass furnace, glass ceramic kiln and tunnel kiln. Also they can be used in iron making industries, like laying ceramic, taphole of blast furnace and tuyere. It can protect the bottom of blast furnace for longlife using.
- 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?
- 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?
- 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: 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?
- The most thermal insulation is a variety of cotton fiber insulation, but the temperature is not very high. Alumina polycrystalline fiber cotton, about 1600 degrees, mullite polycrystal, mixed polycrystal, lower temperature. Zirconia material is said to be capable of high temperature because zirconia has a melting point of 2700 degrees, 700 degrees higher than alumina. But it's not used. It's not clear.
- 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.
