- 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: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: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 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 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:What material is heat insulated and not afraid of fire?
- Foam as a kind of important organic insulation materials, there are two kinds of polystyrene and polyurethane foam, which was published in 30s, the production in our country began in late 50s and 60s, which is characterized by the effect of thermal insulation performance, light weight, sound absorption properties, but the organic materials and brick wall with construction is difficult. Need the polystyrene foam plate is adhered in the walls with special binder and coupling agent, after a plurality of process, the construction is very complex. Moreover, foam plastic products have poor aging resistance, low service life, and waste materials can not degrade and cause white pollution.
- 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: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.
