FAQ

Client:what is your company advertage?

Us:1, Our company has established a complete quality assurance system,we have been certified by an array of ISO.

2, There is almost no black spot on the surface of our bricks. It represents more even and neat color due to the superior raw material and strict selection.

3, Our product enjoys higher refractoriness under load because of its higher heat treating temperature in the high temperature zone of the furnace.

Client :why should we choose you?

Us:we can ensure qualified products only and 100%exfactory pass rate.

$refractory fireclay brick RN-42$

Q: What's the difference between a high aluminum brick and a clay brick, two?: Light clay brick, refractory material is a kind of high porosity, low density, low thermal conductivity of refractory material, refractory materials called lightweight refractories, it includes insulating refractory products, refractory fiber and refractory fiber products. Heat insulation refractory material is characterized by high porosity, general 40%-85%, low volume density, lower than 1.5g/cm3, low thermal conductivity, generally lower than 1.0W (m.K). The utility model has the function of heat insulation of an industrial furnace, and can reduce the heat dissipation loss of the kiln, save energy, and can reduce the quality of the thermal engineering equipment. The mechanical strength, wear resistance and slag resistance of insulating refractory material are poor, and it is not suitable for the load-bearing structure of kiln and direct contact with slag, burden, molten metal and other parts.

Q: is it good to use firebricks to preserve the heat of rto furnace? Is there any other good ideas?: 1. what variety and grade of refractory materials should be chosen to build all parts of the industrial furnace?; 2. is the origin of these materials be assured? mesothern resistance furnace, lightweight refractory brick, refractory fiber, bead brick of 1000 degrees; fuel heating furnace, refractory clay brick, high alumina brick, silica brick, carborundum brick, refractory castable, the plastic refractory of 1300 degrees; heat treatment furnace, refractory clay brick, refractory fiber of 1100 degrees; high temperature salt bath furnace, refractory clay brick, high alumina brick, zircon brick, refractory castable of 1300 degrees; high temperature resistance furnace, lightweight refractory brick, high aluminum bricks, lightweight alumina brick, lightweight refractory clay brick of 1400 degrees; molybdenum wire furnace, alumina brick, corundum brick, carborundum brick, finished alumina hollow ball product of 1650 degrees; cupola, refractory clay brick, carborundum brick, dolomite Brick, carbon brick, graphite brick of 1650 degrees; arc furnac, high alumina brick, silica brick, magnesia brick, magnesia brick, magnesia chrome... Corundum brick, carbon brick, magnesia chrome brick, magnesia brick, high aluminum brick, silica brick, finished alumina hollow ball product of 1700 degrees; cupola, refractory clay brick of 1650 degrees;

Q: Where the refractory bricks rider bricks that are used for building arch and vault should be put?: Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.

Q: What are the differences between thermal?insulation?bricks and refractory bricks?: Thermal insulation brick is thermal insulative; refractory brick is high temperature resistant.

Q: Clay brick, red brick, always fried brick how to do?: Small white stones, such as Magnesium Oxide and limestone (calcium carbonate). Take "containing limestone" (calcium carbonate) stones, after firing, into lime (calcium oxide), put a long time, absorb the moisture in the air, will cause the lime (calcium oxide) reduction, volume expansion, resulting in fried brick.

Q: Why can't build refractory brick behind the skew block?: refractory is heat expansion and cold contraction, it is also called refractory?brick, can resist high temperature up to 580-770 degrees. Mainly used for the smelting furnace. faint?yellow or brown, when it is high temperature, it will squeeze toward the center. Refractory material made of refractory clay or other refractory raw materials. the shortened form of fefractory brick is brick. vault will be extrusion deformation. Refractory material with a certain shape and size

Q: Whether the fire bricks are needed to be poured before construction?: It should be properly watered, according to its water absorption rate: Need to soak and dry in the shade. There is no need to do like the ordinary red brick

Q: how to test the high alumina refractory brick mixed alumina?: Test

Q: What is sintered non clay brick?: According to the different production process of bricks into sintered brick and non sintered brick. Sintered brick in China has more than two thousand years of history, is still a very wide range of wall materials. Many kinds of brick, according to the raw materials used for clay brick, shale, coal gangue brick, fly ash brick, lime sand bricks and slag brick;
