Product 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:What matters should be noticed when using clay refractory bricks in a glass kiln?
There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic
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:what kind of refractory brick is suitable for 1300 degrees converter?
High alumina bricks of above 3 grade, containing more than 60% aluminum
Q:Blend 12% fireclay and 88% refractory cement. Moderate water and mud are used to pile up firebricks?
Refractory bricks can irectly be liner. Lightweight mullite brick can be used for relatively longer time. If there is no mullite brick, use mud said above for some time, then continue to use by patching up.
Q:In tunnel kiln, what is the meaning of refractory proportion 2.0?
That is the volume density of the refractory brick
Q:Are refractory bricks necessarily needed to build a kitchen stove?
It will be better to use refractory bricks for long term because of its high temperature resistance
Q:How to choose the proper refractory bricks when buying the refractory bricks?
Crack condition. 4. 6. Inspection of dimensions. Conditions of pits and swells and lack of edges or angles. The inspection of refractory bricks' appearance quality and the condition of the affecting with damp.
Q:What is the raw material for the production of refractory bricks?
Mainly Magnesium Oxide, use sodium silicate as a binder.
Q:th choose of different refractory bricks in the rotary kiln
According to the characteristics of each belt, magnesium chromium brick. Take the most kiln foe example, the configuration of kiln refractory is not the same, the burning of the product is not the same. there are many kinds of rotary kiln. magnesia bricks are generally used in high temperature zone, anti-stripping alumina brick,silmo brick are used in temperate zone, clay brick is mainly used in low temperature zone. generally inlet and the outlet use corundum mullite, wear-resistant castable, spinel brick,etc. select brick of proper performance, but also take into account the economy
Q:what is the ratio of refractory mortar and refractory bricks, such as how much refractory mortar is needed for a ton of refractory bricks?
Go to the refractory factory to buy some refractory clay that is of the same material as refractory bricks, generally boiler uses clay refractory mortar.
