Q:What kind of material is good to be laid on the kiln car, refractory brick?
Use blankets to suspend ceiling, and modules for wall
Q:What is the perservation method for refractory bricks used for cement kiln?
The hydration resistance ability is better than the alkaline materials, 1 years will be no problem if the environment is good, alkali-resistant bricks used in cement kiln brick refractory brick (magnesia-chrome brick, the preservative time will be longer, the remaining products should also be moistureproof. No matter what refractory materials, phosphate brick. If the package is complete, it must be stored in a dry and rain-proof environment, silmo brick. Anti-stripping alumina brick, if is not immediately used, it's necessary to take measures of moisture proof, such as spinel brick must be moisture-proof
Q:What to do if refractory bricks saltpeter when they are used outdoor
Efflorescence is usually dialysised from brickwork joints, dealing with the gap is ok These white substaince inside the pan tile: Cement efflorescence efflorescence is wow cake section from light leather intestinal common disease inumiya Hua building surface, according to their different causes and manifestations, there is pan cream, white, whitening, cream, on the walls and decorative surface erosion and other names, is the change of soluble saline alkali soil, adobe, brick, cement, mortar, concrete, masonry, ceramic tile, paint and other building materials with temperature, humidity and other external environment, in a water absorption, water transfer, water evaporation process with physical and chemical changes of the original building material damage disease phenomenon, erosion degree also has the very big difference there is a common, get damp, foaming, powder, drum, hollowing, cracking, spalling, mildew and crystallization phenomenon. Cement efflorescence may have some relationship with the quality of the cement, sand, water, air, temperature, humidity, it is a common fault in building. Use cement to do the pebble shape, it also prones to the above problems: A layer of white stuff on the surface. Terms of settlement: Scrape the dust in brickwork joint, pointing again. Use special pointing agents, more resistant to corrosion, not easy to efflorescence.
Q:Can red bricks be burned in tunnel kiln which used to burn refractory brick?
It can be used to burn the red brick, as long as the temperature is almost the same
Q:Should kiln be warmed before the ignition of the new furnace?
If you don't have to heat up the furnace. The new furnace must be heated up, and the temperature should be increased according to the heating-up furnace curve, so the current situation you meet is appeared
Q:How many pieces of porous brick is equal to one ton?
Refractory bricks are generally classified into two types, that is, shapeless refractory materials and shaped refractory materials. Shapeless refractory material: Also known as castable refractory, is hybrid power material composed of a variety of aggregate or a kind of aggregate and one or more kinds of the mixture of adhesive particles, it should be used evenly mixed with one or more kinds of the liquid, which has strong liquidity. Shaped refractory material: The general making of firebrick, there are standard rules for the shape, can also temporarily process according to need of building and cutting. The following are the specifications. fireclay bricks 230*114*65 each block 3.0 - 3.6 kg; special-shaped fireclay brick 230*65/55*114 each block 2.8 - 3.3 kg; the reason for the weight's ranges is that because the quality is different, in general, heavy density, good quality!
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:What are the differences between diatomite brick and ordinary refractory bricks?
The volume density of diatomite brick is 3.9 * 10-6, good compressive strength, belongs to the small outer insulation, spinel brick.
Q:What is the meaning of special shaped refractory brick material n-2b?
In fact, there are many kinds of refractory bricks, titanium, high alumina refractory brick, after drying. The mineral composition of the clay brick is mainly kaolinite (Al2O3·2SiO2·2H2O) and 6% ~ 7% impurities (K, etc.). Clay refractory bricks are iron oxide sintered by 50% soft clay and 50% hard clay clinker ingredients according to a certain granularity requirements under the high temperature of 1300 ~ 1400 degrees), perlite
Q:how much fireclay is needed for 10000 refractory bricks?
The amount of mud used for T-3 refractory brick is 0.3KG. if the tiler is skillful, the furnace should have joint of 2mm.
