Q:What's the reason of cracks in refractory bricks?
This is inorganic nonmetallic material
Q:What raw materials are used for refractory bricks
Phenolic resin, clay, powder and other materials, nitride materail, boron carbide, silicon carbide, silica raw material three, soil: fluorite, magnesia-alumina spinel Aluminum soil, calcium aluminate cement, corundum, andalusite, chlorite, silica solution, which is mainly divided into six categories, sillimanite, vermiculite refractory bricks raw material composition of refractory brick, there are many raw material kinds of refractory bricks, mullite, mine: Soil, Sialon, forsterite, pyrophyllite: Metal aluminium powder, ore, stone: Pottery, zircon sand, quinidine sulfate, dolomite, kaolin: The fifth raw material of chrome ore, sodium silicate, diatomaceous earth is the second raw material: Asphalt, sand, shale ceramisite. One of the raw materials, stone powder, the fourth raw material is magnesite, the sixth raw material is silicon metal powder refractory bricks, sand, kyanite, silica powder, aluminium oxide, aluminum sol, quartz sand, perlite, cenosphere, graphite
Q:Which is better for tunnel kiln suspended ceiling, refractory brick or ceramic fiber module ?
If there is no strong hot erosion by airflow, then module is certainly better
Q:Is refractory brick afraid of rain?
High alumina clay is not afraid of rain, but covering is better, magnesium carbon refractory brick had better not be rained.
Q:What kind of material is good to be laid on the kiln car, refractory brick?
It depends on the temperature. General thermal insulation brick is ok, when temperature is high, use mullite, and when temperature is not high, alumina is ok
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's the difference between fired clay bricks and sintered porous bricks?
Fired clay brick is a common brick made of clay as the main raw material. It is divided into five strength grades MU30, MU25, MU20, MU15 and MU10 according to the compressive strength. Strength, resistance to weathering of radioactive material and qualified brick, according to the size deviation, appearance quality, efflorescence and lime burst divided into high-class product (A), Al (B), (C) three qualified product quality grade. Excellent products for drywall and wall decoration, wall can be used for mixing first-class products, qualified products. Medium frosted bricks should not be used for damp parts. The shape of the brick is right angled hexahedron, its nominal size is: 240MM long, 115MM wide and 53MM high. The product mark of brick is written according to the product name, category, intensity grade, quality grade and standard number.
Q:What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?
except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
Q:How to prevent high alumina refractory brick from producing crack when reproduce high alumina refractory brick?
1-1, on the 1 in order to prevent the emergence of crack in the production of high alumina refractory brick. 2 is appropriate, the water absorption rate of the tube mill should be controlled below 6%, the excess air coefficient controlled between level 1 and 2. The water absorption rate of clinker of bauxite with high alumina controlled under 4%-5%, making the high aluminum refractory brick burning in a smoothly and steadily weak oxidation atmosphere, and should be adjusted by thermotechnic
Q:Small size black brick can replace refractory bricks for wood burning fireplace?
No, black brick has no thermal insulation effect.
