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:How to prevent high alumina refractory brick from producing crack when reproduce high alumina refractory brick?
1-1, on the 1 in order to prevent the emergence of crack in the production of high alumina refractory brick. 2 is appropriate, the water absorption rate of the tube mill should be controlled below 6%, the excess air coefficient controlled between level 1 and 2. The water absorption rate of clinker of bauxite with high alumina controlled under 4%-5%, making the high aluminum refractory brick burning in a smoothly and steadily weak oxidation atmosphere, and should be adjusted by thermotechnic
Q:T38 size of high alumina refractory brick
high alumina brick, according to the aluminum content, is divided into four grades, the aluminum content of the first grade is no less than 75%, also called the special high alumina brick; the aluminum content of the second grade is no less than 65%, the third grade is no less than 55%; the aluminum content of super high aluminium brick is more than 85%; If the shape is very irregular, it is usually called the super special high alumina brick. in short, there is a universal type of high alumina brick except for standard high alumina brick, customised according to the specific appliction of the kiln.
Q:How to prevent the refractory bricks from burning to crack?
This may result from formula. Prevent the refractory bricks from being overweight. Firstly, sintering agent should not exceed the standard, when sintering, bricks must be well piled to piled bricks, and the bricks must be dry.
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: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:What are the differences between diatomite brick and ordinary refractory bricks?
The volume density of diatomite brick is 3.9 * 10-6, good compressive strength, belongs to the small outer insulation, spinel brick.
Q:Should refractory cement hang inner core when use carbon steel pipe make water heating hearth by self?
The main purpose of adding refractory cement or refractory brick is to avoid the sulfur in coal in the combustion process of corroding metal, especially under the conditions of high water content and low temperature of flue gas. If use natural gas after desulfurization, without considering the life circumstances, can not be adopted, but the carbon steel pipe is unsuitable for what you said, safety first! Earnestly!
Q:The service life of the refractory brick of the intermediate frequency electric furnace, how long is the replacement period.
There is no standard. As long as the induction coil can be fixed and furnace lining can be built, the service life will be different. Replace it if it's broken, and there is no problem to take it apart. Buy a backup. And the textures of refractory brick are not the same in different places.
Q:How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.
If the raw materials are different, then the redness is different under different temperatures.
Q:What kind of refractory brick is used for industrial furnace?
High aluminum in cement plant. Mills use MgO-C, high aluminum ect; glass furnaces use Luo 8. different kiln and parts use different bricks.
