General Information of Low Porosity Fireclay Brick DN15

Our corporation produces a comprehensive range of Low Porosity Fireclay bricks, with 30% to 55% alumina content, all of these bricks exhibit excellent performance.

Our Low Porosity Fireclay bricks are the final result of blending excellent calcined flint clay and calcined bauxite, with cutting-edge technology, adding superfine powder, after mixing, drying, forming, in the high temperature shuttle kiln. We ensure you that the Fireclay Bricks made by us possess high quality standard and have gone through all the complicated quality control parameters. Their durability and strength adds life to the structure and they have the capacity of bearing high temperature.

Low Porosity Fireclay Brick

Feature of Low Porosity Fireclay Brick DN15

Resistant to thermal shock, abrasion, chemical attack

High ability for anti-abrasion during work

Low shrinkage degree under high temperature so as to maintaining integrity of the furnace lining

Low apparent porosity, and low Fe₂O₃ content to reduce the carbon deposit in the blowhole and avoid the bricks broken in case of expansion

Applications of Low Porosity Fireclay Brick DN15

Low Porosity Fireclay Brick DN15 is mainly used in glass furnace.

Q: What types of building blocks do you have?: Ordinary housing: building brick (clay brick), and non sintered brick (sand lime brick, fly ash brick, cement brick, etc.)

Q: What is the material of refractory brick used in the high temperature zone of the kiln?: The ordinary generally use clay high alumious fireclay brick. GB/T 3994-2005 insulating refractory brick. What with good material is high-grade thermal insulation refractory brick. GB/T 3995-2006, high alumina thermal insulation refractory brick , model A13, is made of aluminium oxide, A13 50U, senior heat insulatio brick B5

Q: Mainly use the raw materials inside refractory bricks,: Go to the refractory factory to buy some refractory mortar that has the same texture of refractory bricks, the general boiler use clay refractory mortar.

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's the price of clay bricks?: Clay brick in the fast price of 2.4 yuan or so, the price of 650-800 yuan per ton. Mainly depends on the amount of aluminum. Clay brick consists of heavy clay brick and light clay brick.

Q: what kind of refractory brick is suitable for 1300 degrees converter?: The furnace cap tapping shaft part should use MgO-C brick with high slag resistance and thermal shock resistance, the steel side can be slightly thin, bottom carbon content may be appropriate less.

Q: What are the differences and uses of non clay bricks, non clay bricks and ordinary red bricks?: Just bricks without claySuch as foam hollow bricks, straw bricks, and some other cement bonded solid, hollow bricks and so on

Q: The service life of the refractory brick of the intermediate frequency electric furnace, how long is the replacement period.: There is no standard. As long as the induction coil can be fixed and furnace lining can be built, the service life will be different. Replace it if it's broken, and there is no problem to take it apart. Buy a backup. And the textures of refractory brick are not the same in different places.

Q: Why is there cracks in the use of refractory bricks?: Several reasons for the emergence of cracks: (1) temperature difference stress (2) mechanical stress (3) crystal type change stress

Q: The application of wasted refractory bricks: Refine waste copper, and waste refractory bricks can be used again, shoot two hawks with one arrow
