- 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.
- Q:Corrosion mechanism of iron on refractory materials
- Iron oxide can not be used as refractory,
- 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 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:Mullite bricks in alumina alumina is what?
- Mullite (3Al2O3 - 2SiO2) high alumina refractory materials as the main crystal phase. The general alumina content in 65% ~ 75%. In addition to mineral composition of mullite, alumina containing low also contain a small amount of glass phase and cristobalite; alumina containing high also contain a small amount of corundum. Highrefractoriness, up to over 1790 DEG C 1600. Load softening start temperature to 1700 DEG C. Compressive strength at room temperature is 70 ~ 260MPa.. The thermal shock resistance of sintered mullite and fused mullite brick two. Sintered mullite brick with high bauxite clinker as the main raw material, adding a small amount of clay or alum clay as binder, forming and sintering made of fused mullite bricks with high alumina and bauxite, refractory clay as raw material, adding charcoal or coke fines as a reducing agent, formed by reduction of electric melting method to manufacture. The crystallization of fused mullite than sintered mullite, thermal resistance Shock resistance than sintered products. The uniformity of content in alumina mainly depends on their high temperature properties and mullite phase and glass distribution. Mainly used in blast furnace, furnace top and bottom furnace, glass furnace regenerator, sintering kiln, petroleum cracking system dead lining.
- 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: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: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.
