- Inquire about price/MOQ

Q:What kind of refractory brick is suitable for 24*28m rotary kiln of 5,000 tons?
Magnesia spinel brick and magnesia hercynite brick
Q:Is the thickness of the kiln lining and the refractory brick the same concept?
This is certainly not the same. The thickness of the refractory brick can be arbitrary, the thickness of the kiln lining is generally designed according to requirement
Q:Can fly ash brick keep warm?
Sure, I do fire-resistant insulation bricks, we also use fly ash ah!
Q:How much is a refractory brick?
This question is too general, refractory bricks according to the use of the environment and industry, there are a variety of materials, a variety of specifications, prices vary greatly.
Q:The difference between the high aluminum corundum brick and corundum mullite brick
Tiles are called floor tiles, floor tiles, polished tiles and glazed tiles are glazed tiles, bricks are samples of all kinds of tiles, ceramic tiles will be placed in the tile shop, tiles are also divided into outer wall tiles and inner wall tiles, modern brick and antique brick
Q:What are the differences between high alumina brick and high alumina refractory brick?
High alumina brick is generally the national standard T-3 models, high alumina refractory brick is brick with more than 55% of aluminum content including special-shaped brick.
Q:Energy saving bricks or bricks?
Energy saving brick may be cement slag, or cement, water residue, cement, coal ash, etc. overview
Q:Can refractory bricks be used to build a house?
Refractory brick can be used to build houses, but you can not use ordinary cement to build, the cost is 3 times than that of ordinary brick.
Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of brick has the highest refractory temperature?
It depends. if high alumina brick is used in kiln, its temperature is above 1700 degree, clay brick is between 1500 degree to 1750 degree, magnesia bricks and magnesia-chrome bricks are about 1500 degree to 1650 degree.
Q:98% acid tank cofferdam can use acid resistant brick?
Hydrogenation unit of hydrogen and high pressure and temperature, the system memory in the U2S and NH3, therefore, the corrosion problem of hydrogenation unit should also be emphasized, main methods to solve the corrosion problem of hydrogenation device is reasonable material, strengthen the surveillance and detection in use.
