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.

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?

The alumina fiber has a maximum resistance of 1700 degrees, and the zirconium fiber is generally 1700 to 2200 degrees

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?

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: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.

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.
