Q: can the red brick be used as refractory brick?: 1200---1750 of the refractory bricks, below 1000 degrees of red brick brick is ok.

Q: how much is the content of the high alumina of refractory brick?: linear?change?on?reheating is small and Slag resistance is good, matte smelting, good thermal shock resistance used refractory materials should be resistant to high temperature: In front of the furnace, the temperature can reach 1800, copper blowing. The maximum temperature in the smelting furnace area is on the top, pyro-refining and electrorefining, magnesia chrome brick, magnesia chrome castable, magnesia alumina brick. The commonly used refractory materials is direct-bonded?magnesia-chrome?bricks, which has large volume density. manufacturing technique of copper smelting consists of five parts, Clay brick

Q: Shale brick and clay brick? Answer before you know it: Is the shale as raw material for high temperature baked bricks using shale and coal gangue, shale sintered porous brick, hollow shale brick, shale brick, high insulation, water wall and other types of modular brick.

Q: What are the differences between sintered bricks and refractory bricks?: Sintered bricks belong to a type of refractory bricks.

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: 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: Why masonry walls must not be mixed with clay bricks?: Generally speaking, the seismic performance of masonry structures is weaker than that of concrete structures. Therefore, it is possible to have some concrete frames or seismic walls in masonry, but the building must evaluate the seismic performance according to the masonry structure. But the concrete structure can not consider the masonry bearing, and the masonry wall is the self load wall or the light partition wall.

Q: Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?: They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem

Q: what kind of refractory brick is suitable for 1300 degrees converter?: magnesia-carbon brick, you can also use MgO-Al2O3 castable, it is good too.

Q: Are buildings allowed to use red bricks?: Is the red 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, invented by the babylonians.
