- 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
- 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?
- 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: What are the high temperature insulation materials?
- Followed by a variety of lightweight bricks, alumina hollow ball, lightweight brick is relatively high temperature, about 1600 degrees. The others are low.Then there's the heavy brick. Heavy alumina brick, corundum mullite, can withstand 1750 degrees -1800 degrees. Mullite, cordierite lower lows.
- Q: What kind of refractory material is used in the hearth of reverberatory furnace?
- 1400 degrees below can use clay brick, high alumina brick; 1400 to 1700 can use mullite bricks, heavy corundum brick; more than 1700 can use zirconia brick, such as zirconia brick
- 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.
