Product Description:


Description:

Refractory Fireclay Bricks with Tunnel Kiln 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 Refractory Fireclay Bricks with Tunnel Kiln 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

Q:does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
if use the rock wool or aluminum silicate, the furnace arch and furnace wall of biomass boiler all use refractory brick, and outside the furnace wall there is a layer of insulation material, some is perlite coal-fired boiler
Q:what should press on the heat preserving cotton above the suspended ceiling refractory brick ?
you can also put Z shaped steel on the purline, put heat preserving cotton on the roof boarding, it is easy to oprate.
Q:Can mud and salt be used as refractory materials
Clay can be used as a refractory material, but salt can certainly not be used.
Q:What are the factors that determine the weight of the refractory bricks?
(5) Under high temperature, the volume is stable, the inner part of brick will produce unrecoverable volume shrinkage or expansion because of the internal transformation. Therefore, masonry inner will produce stress to make the material break and peel off, and the weight of a ton of bricks is determined by the bulk density and quantity, how much is the weight of refractory bricks, refractory bricks should have the ability to resist the damage, the weight of a piece of brick is determined by the bulk density: Refractory bricks are used under high temperature for a long term: Refractory bricks in the use of the process. Cooltech refractory brick used in various high-temperature equipment: The temperature of some parts of metallurgical furnace and other industrial furnace is uneven due to rapid temperature change during operation. (3) good thermal stability: Refractory bricks should not only have a high fusion temperature, no softening deformation and collapse, causing damage to the masonry. (4) strong resistance to slag: Modern metallurgy and the other industrial furnace heating temperature is generally between l000~1800. Refractory bricks should have the performance that is not easy to melt under high temperature. Therefore. Therefore, it is subject to high temperature conditions of physical and chemical corrosion and mechanical damage, the refractory brick must have the ability to resist high temperature chemical corrosion, the volume of refractory brick is required to be stable under high temperature. (2) High-temperature structural strength, chemical corrosion of metal, but also should have been built in the stove brickwork load or other mechanical vibration, often has the high temperature slag, so the refractory materials performance should meet the following requirements: (1) high refractoriness
Q:What are required for high temperature refractory bricks?
good thermal shock resistance:
Q:What is the relationship between the firing process and the manufacturing technique of fireclay bricks?
Q:What is the best color of refractory brick
Gules
Q:How to classify light refractory bricks?
It should be classified based on the production materials of refractory brick! In addition to ordinary light brick (cenosphere material), mullite poly light ball, there is lightweight high aluminum brick, lightweight clay brick, diatomite brick etc.!
Q:Is refractory brick afraid of rain?
High alumina clay is not afraid of rain, but covering is better, magnesium carbon refractory brick had better not be rained.
Q:There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?
Heat insulation
