- Q: What are the differences between high alumina brick and high alumina refractory brick?
- with the increase of the fire temperature and other indicators, Al2O3 content is also improving. the general content of Al2O3 in high alumina brick is more than 60% .
- Q: What is the specific heat of a refractory bricks (clay)?
- Approximately it's about 2000; M3 specific heat is wrong with this argument, two degree clay is 1730 degrees, three degree clay is 1690 degrees, clay bricks are mixture, bulk density, 1900KG/, only elementary substance has specific heat refractoriness.
- Q: does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
- if use the rock wool or aluminum silicate, the furnace arch and furnace wall of biomass boiler all use refractory brick, and outside the furnace wall there is a layer of insulation material, some is perlite coal-fired boiler
- Q: General used refractory brick T-20 / T-39/ T-206 specifications and dimension
- No T-206 model (we produce the clay) T-20 and T-39 are the size of 230*length, 113* width and 65/45 thickness, T-20 is a vertical arch brick and T-39 is horizontal arch brick.
- Q: What are the type, location and the physical and chemical effects of the refractory brick used in the cement rotary kiln?
- But most people use high alumina brick or clay brick, G6 refractory brick. The specific masonry location, such as G4 refractory brick, standard brick, T38, OD, T39, according to the length of your rotary kiln, many kinds of refractory bricks are used in cement rotary kiln, the specific size of the inner diameter should be calculated in detail
- Q: What matters should be noticed when using clay refractory bricks in a glass kiln?
- There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic
- Q: When the coal-fired steam boiler is built, it is necessary to build a common red brick between the refractory bricks. May I ask what is the requirement for this common red brick?
- It has requirement for the external dimension (but not as strict as the requirement for the refractory brick), or it can not meet the thermal insulation effect and affect the appearance, and the appearance of the furnace wall is not beautiful
- Q: Are buildings allowed to use red bricks?
- Is the red brick with clay, shale, coal gangue as raw materials, crushing, mixing kneading with artificial or mechanical pressing, sintering and building bricks after drying at 900 centigrade temperature by oxidizing flame firing, invented by the babylonians.
- Q: what is the ratio of refractory mortar and refractory bricks, such as how much refractory mortar is needed for a ton of refractory bricks?
- Go to the refractory factory to buy some refractory clay that is of the same material as refractory bricks, generally boiler uses clay refractory mortar.
- Q: What is the difference between the refractory brick and the thermal insulation brick
- Refractory bricks are used in the stove, in order to prevent from burnouting the stove under high temperature. Thermal insulation brick is used for preserving heat, is to heat preservation
