Product Description:

Description:

High alumina fireclay Brick for Heating Furnace is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.

 

This series of High Alumina fireclay Brick for Heating Furnace are made of selected high alumina bauxite, kaolin clay, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature

 

Product Applications:

1. Furances of glass,coke oven,electric and so on
2.Furnaces of metallurgy industry, heat treatment furnace
3. Furnaces of chemical industry and construction industry.
4. Furnace of incineration of garbage, recirculating fluidized bed furnace
5. Standard sizing: 230 x 114 x 65 or 75 or 25  mm others up to the client

 

 

Main Product Features:

1. Low porosity,High bulk density.

2. High Cold Crushing strength.

3. High refractoriness under load.

4. High mechanical strength.

5. Good resistance to erosion.

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 is the proportion of lightweight fireclay bricks?
The ingredients are mixed with water to form plastic mud or mud, by extrusion molding or casting molding, after drying at 1250-1350 Deg. C oxidation atmosphere sintering. The volume density of commonly used clay bricks is between 0.75-1.2g/cm3. In reality, the proportion is 1.
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:90 porous brick and ordinary shale brick, clay brick difference
Porous brick is the original clay brick (now don't let in) and shale increased by a certain gap, but it is also the porosity, thickness is 90, not 53 of the original, there are also some differences in the use of solid brick and. Not for underground use.
Q:Are clay bricks radioactive?
Radiation is almost invisible, radiation is almost everywhere.
Q:Why do some people say that clay brick insulation effect is good, and some people say that bad, in the end what is right?
The heat preservation effect should be taken away from the heat insulation capacity of the material. The ordinary clay brick has small heat capacity and slow heat conduction, so it is more thermal insulation.
Q:Can refractory bricks be used to build a house?
Refractory brick can be used to build houses, but you can not use ordinary cement to build, the cost is 3 times than that of ordinary brick.
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 specific heat of a refractory bricks (clay)?
Approximately it's about 2000; M3 specific heat is wrong with this argument, two degree clay is 1730 degrees, three degree clay is 1690 degrees, clay bricks are mixture, bulk density, 1900KG/, only elementary substance has specific heat refractoriness.
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.
