General Information of Fireclay brick
Our corporation producesa comprehensive range of Fireclay bricks, with 30% to 55% alumina content, allof these bricks exhibit excellent performance.
Our Fireclaybricks are the final result of blending excellent fused alumina and silicon asthe main raw materials with cutting-edge technology, adding superfine powder,after mixing, drying, forming, in the high temperature shuttle kiln. We ensureyou that the Fireclay Bricks made by us possess high quality standard and havegone through all the complicated quality control parameters. Their durabilityand strength adds life to the structure and they have the capacity of bearinghigh temperature.
Feature of Fireclay Brick
Resistant tothermal shock, abrasion, chemical attack
High ability foranti-abrasion during work
Low shrinkagedegree under high temperature so as to maintaining integrity of the furnacelining
Low apparentporosity, and low Fe2O3 content to reduce the carbondeposit in the blowhole and avoid the bricks broken in case of expansion
Applications of Fireclay Brick
Fireclay brick is mainlyused in the part of throat, stack, hearth, bottom for blast furnace and thestack for a big blast furnace.

- Q:Are clay bricks radioactive?
- Radiation is almost invisible, radiation is almost everywhere.
- Q:How many squares of a ton refractory bricks?
- About 2 tons , general one square clay brick is about 2 tons, from 2, one square corundum brick or magnesia bricks can reach 3 tons, it should say one square is how many tons. if it is high aluminum, then see the content of aluminum. It mainly sees what refractory bricks, because the volume and density of refractory bricks are relatively large.2 tons to 2
- Q:What mud is the refractory brick made of?
- The main material of the ordinary refractory brick is clay, the main component is aluminium oxide.
- Q:Shale brick and clay brick? Answer before you know it
- The clay brick with clay, shale, coal gangue as raw materials, crushing, mixing kneading with artificial or mechanical pressing, sintering and building bricks after drying at 900 centigrade temperature by oxidizing flame firing.
- Q:How many years are the service life of chimney lining refractory brick?
- Capacitance magnesite, seawater magnesite, should be the alkaline refractory brick, magnesia-alumina spinel can absorb hydrogen fluoride, generally are magnesia brick, magnesium iron ore, forsterite, dolomite, magnesium dolomite, magnesium silica sand, magnesia-chorme spinel and magnesia chrome sand: Magnesia mineral, magnesium calcium sand, magnesite, magnesium dolomite sand, dolomite, mainly is cordierite
- Q:What are the factors that determine the weight of the refractory bricks?
- (5) Under high temperature, the volume is stable, the inner part of brick will produce unrecoverable volume shrinkage or expansion because of the internal transformation. Therefore, masonry inner will produce stress to make the material break and peel off, and the weight of a ton of bricks is determined by the bulk density and quantity, how much is the weight of refractory bricks, refractory bricks should have the ability to resist the damage, the weight of a piece of brick is determined by the bulk density: Refractory bricks are used under high temperature for a long term: Refractory bricks in the use of the process. Cooltech refractory brick used in various high-temperature equipment: The temperature of some parts of metallurgical furnace and other industrial furnace is uneven due to rapid temperature change during operation. (3) good thermal stability: Refractory bricks should not only have a high fusion temperature, no softening deformation and collapse, causing damage to the masonry. (4) strong resistance to slag: Modern metallurgy and the other industrial furnace heating temperature is generally between l000~1800. Refractory bricks should have the performance that is not easy to melt under high temperature. Therefore. Therefore, it is subject to high temperature conditions of physical and chemical corrosion and mechanical damage, the refractory brick must have the ability to resist high temperature chemical corrosion, the volume of refractory brick is required to be stable under high temperature. (2) High-temperature structural strength, chemical corrosion of metal, but also should have been built in the stove brickwork load or other mechanical vibration, often has the high temperature slag, so the refractory materials performance should meet the following requirements: (1) high refractoriness
- 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:How are shale porous bricks and clay porous bricks distinguished?
- Dimensional deviation is less than clay brickBecause the plastic index is better than that of clay shale itself, although the requirements of the national standard for the size deviation of sintered brick is the same, but the size deviation of shale in actual production is generally less than the clay brick.
- 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.
