Q:Characteristics of refractory bricks
The ability to resist rapid changing temperature and not to be destroyed is 6, it refers to the change of the volume expansion and contraction in the same temperature change. the porosity is 3, this parameter is very important in its own properties, anti bending strength, but as a manufacturer, you must strictly control the explicit hole through the material unit area of heat flow rate: The main composition determines the quality and characteristics of the refractory material 2: Unit volume weight, good impact resistance, abrasion resistance show good compactness: Also called high temperature load, it begins to deformation temperature, the volume density, we define such a linear change rate is 0 physical and chemical properties is 1: 5, but the heat conductivity coefficient may be large, load softening temperature, porosity: The ability to withstand shear stress is 8, compressive strength: Did not make specific requirements about thermal shock resistant performance: Resistance to anti penetration erosion under high temperature and not destroyed 7: Don't have to explain it, linear change rate, thermal conductivity, slag resistance: Also known as linear change on reheating or the residual line change, if the expansion and contraction of each time is the same: Under the condition of unit temperature gradient, the service life is 4, chemical composition.
Q:What is the name of the white clay refractory brick
Kaolin
Q:Is there any special requirements for the building blocks of the smoke and gas wells, how about the refractory bricks?
There are no special requirements. Not necessarily need refractory bricks, red bricks are ok. The building size of the flue is according to the smoke exhaust rate.
Q:How to repair the boiler?
use refractory bricks and plastic refractory
Q:What is the density of the high alumina refractory brick?
According to the quality, the general level is two point four to two point seven or so
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:Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?
They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem
Q:is there any requirement for radioactive materials in refractory materials.
they all do not cause radiological hazards to the environment, so no requirements! analyze rom the element , magnesia. Do not know if it is useful, but material used by refractory materials, firstly any chemical elements are radioactive, human beings can not close, then, such as silicon dioxide: If it is radioactive. analyze from use, such as bauxite, does not have the use value
Q:Why is there cracks in the use of refractory bricks?
Several reasons for the emergence of cracks: (1) temperature difference stress (2) mechanical stress (3) crystal type change stress
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?
unnecessary
