Q: There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?: When the steel is made, and wear) to complete the purpose of steelmaking, the liquid inside the kiln is melted liquid steel (1550 DEG C), erosion, only the masonry of refractory brick (melt above 1550 DEG C and has a certain strength) can resist various effects of molten steel (melting

Q: How to distinguish between sintered clay brick and sintered coal gangue brick: Coal gangue is an industrial waste produced during coal mining. Using coal gangue as raw material for the production of new wall materials, both to protect the ecological environment, but also save the land, save energy, it meets the development policy of wall materials industry in China, is a new wall material attaches great importance to and vigorously support the development of the.

Q: The advantages of using alkalinty refractory brick?: Magnesia chrome and other spinel refractories alkalinity refractories; (2) the alkalescent chrome magnesite refractories, alkaline solvent resistance is strong, usually refers to the magnesia refractory material, dolomite brick and calcareous refractory materials, dolomite refractory materials and lime refractory materials, acid flux or acid refractory chemical reaction. Mainly used in alkaline steel furnace and non-ferrous smelting furnace. Alkaline refractory material at high temperature for alkaline slag. Mainly as the following categories, but the acid slag, forsterite refractories and magnalium: (1)strongly alkaline magnesia brick, magnesia carbon brick and cement kiln

Q: What are the hazards of solid clay bricks?: According to incomplete statistics, China produces about 70000000 tons of standard coal per year of clay bricks.

Q: Can someone tell me the refractory brick in the boiler mixed with what material to build the wall, and what proportion?: Go to the refractory factory to buy some refractory clay that has the same texture of refractory bricks, the general boiler use clay refractory mortar.

Q: What is the problem about splintering when the refractory brick is fired?: There are many bubbles inside the refractory brick, it is also possible that the brick itself is not up to the standard about volume density, then refractory brick fragmentates. There are many reasons, may be in the process of repression

Q: can Methanol burn refractory brick?: Generally speaking, all the fuel can burn, mainly to see the calorific value and consumption ratio

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: Will the heat be taken away by the refractory brick: No, refractory bricks can't be burnouted

Q: What is the density of the high alumina refractory brick?: According to the quality, the general level is two point four to two point seven or so
