Q:what should press on the heat preserving cotton above the suspended ceiling refractory brick ?
you can also put Z shaped steel on the purline, put heat preserving cotton on the roof boarding, it is easy to oprate.
Q:is it correct that the higher the refractoriness is, the better refractory bricks are?
Does not necessarily, it has a great relationship with the compression and bending and corrosion resistance.
Q:Do refractory bricks need to be sent to the lab to test after arriving the site?
Generally speaking, as long as the use of temperature is not higher than 1500 degrees, it is not required to do the test, even if the ordinary refractory brick temperature is about 1500. If the temperature is high, then you do test to determine what kind of texture of refractory brick you need
Q:How to increase the service life of high temperature refractory bricks?
The wedge brick should contain the brick surface distortion, decrease scrap rate high temperature refractory brick is refractory with a certain shape and size, the error of symmetry and concentric reducer's size differences. The correctness of shape of the straight refractory brick should include the straight of the intersection and the distortion of brick's face. Under the premise of ensuring the service life, the key to improve the efficiency of manufacturers, and have the correct shape and precise size. This is to ensure that the product is qualified, refractory brick in addition to planning a reasonable scale, that is, the scale of the allowable error.
Q:The stove which made of refractory bricks and fireclays will produce cracks after being used. How to solve this problem?
The use of low expansion materials will be better. But as for the stove, the appearance of crack is attributed to the selected materials or the environment. And when the temperature is not high, there still seems to be crack, so through expansion joint reservation, not allowing itself to crack
Q:What are the differences between sintered bricks and refractory bricks?
Easily weathered. There is no obvious difference in the usage between fired pavingbricks and refractory bricks; sintered bricks are generally used for residential road and landscape engineering, they do not fade; refractory bricks are used for all kinds of kiln constructions in plant: It is not anti-freeze (when the temperature is below the zero degree, the brick will easily "blister" in the saturated state), the reasons are high compressive strength and high temperature zone' heat insulation and so on. Fired pavingbrick is a powerful vacuum extrusion type. Fire suppression road brick is high temperature furnace brick, which is not suitable to be used as road brick. Its characteristics are: Wear resistance and freeze-thaw resistance (the anti freeze-thaw cycle of brick is more than 50 times in saturated state), non weathering, sidewalks, short service life. Sintered brick belongs to the building material, refractory brick belongs to the industrial kiln material, which is easy to moss
Q:What material is sk-34 on the refractory brick
Electric power; refractory bricks, castable refractory, building materials, chemical, glass, ferrous metals and other industries required refractory and insulation materials, all kinds of thermal insulation cotton products, thermal insulation brick, aluminous refractory cement, perlite and other unshaped refractory materials have been the best-selling products
Q:The harm of wet bricks used in refractory bricks
Increase the natural protection time, increase the baking time, or water can not discharge, this will cause swelling deformation of furnace wall.
Q:can castable refractory replace refractory bricks in rotary kiln?
The heat produced in the welding process will cause local deformation of the rotary kiln, which will affect the dynamic balance, and the construction difficulty in the middle position of the rotary kiln is much larger than that of the refractory bricks. Moreover, the construction quality is not easy to ensure, generally only replace the refractory brick in the kilneye, because the construction of the castable refractory need to weld the anchor
Q:What are the physical and chemical properties of refractory bricks
The thermal shock stability, linear change on reheating, softening temperature under a fixed load, compressive strength under normal strength refractoriness
