Description of fireclay bricks
CMAX fireclay bricks are made from clinker clay. The alumina content ranges from 36% to 48%.
Features of fireclay bricks
1. Lower content of iron, alkaline and impurities, good high temperature properties.
2. Homogeneous structure, light weight, energy saving because lower heat storage in the furnace during cooling cycles.
3. High strength, good thermal shock resistance under high temperature.
4. Precise sizes due to grinding and shaping after firing, which meets the requirement of construction.
Applications of fireclay bricks
CMAX fireclay bricks are commonly applied in blast furnace, hot blast furnace, teeming ladle, glass furnace, etc.

- 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
- Q: The furnace refractory bricks are burnt into ash, what material can resist higher temperature than the refractory brick
- refractory bricks, common clay brick, clay brick, high alumina brick and corundum brick
- Q: What is the coefficient of heat transfer for clay bricks?
- The coefficient of heat transfer is called the total heat transfer coefficient. The current standards and specifications of the state are uniformly named as heat transfer coefficients. The heat transfer coefficient K value refers to the stable heat transfer condition, both sides of retaining structure air temperature is 1 degrees (K, c), 1s in the area of 1 square meters of the heat transfer unit, is w / (M2 - degree (W/) m - K, where K can replace c).
- Q: What is the best color of refractory brick
- Clay refractory brick: Yellow and deep yellow; acid-proof brick: Red, high alumina brick Beige, a little white; square viewing brick: Yellow, red, white, gray, brown, brown, nigger-brown and so on; color is just one aspect of the selection of refractory bricks, it mainly is to see the inherent quality
- Q: why the color of refractory brick is white after high temperature firing when the meteorite is black after the burning?
- There are different reasons. Meteorolites can mainly be divided into three types, iron meteorites (iron nickel alloy): Stone meteorites (the main component is silicate), and stony iron meteorites(the mixture of iron and silicate)
- Q: Will the heat be taken away by the refractory brick
- No, refractory bricks can't be burnouted
- Q: What are needed to make refractory bricks with micro silica?
- Micro silicon powder is used in mortar and concrete, the ore-smelting electric furnace produces a large amount of strongly volatile gases SiO2 and Si, bridges, seaports. It is ferroalloy. When smelt ferrosilicon and industrial silicon (metallic cilicon), micro silicon power is also called silica fume or condensed silica fume, dam, gas emissions and air condensate and deposit by rapid oxidation, water conservancy, airport runway, tunnel, high-rise buildings, subway, railway, highway and culvert. Application fields of silicon power are cement concrete pavement and mine roadway anchor reinforcement and etc.
- Q: how to test the high alumina refractory brick mixed alumina?
- The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
- Q: What can be applied to the burned refractory brick to resist heat shock?
- Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
- Q: What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?
- except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
