General Information

CMAX fireclay bricks are made from clinker clay. The alumina content ranges from 36% to 48%.

Low thermal conductivity        
High refractoriness  
High mechanical strength      
Excellent thermal shock resistance

CMAX fireclay bricks are commonly applied in blast furnace, hot blast furnace, teeming ladle, glass furnace, etc.

Q:can the red brick be used as refractory brick?
1200---1750 of the refractory bricks, below 1000 degrees of red brick brick is ok.
Q:What are the differences between high alumina brick and high alumina refractory brick?
with the increase of the fire temperature and other indicators, Al2O3 content is also improving. the general content of Al2O3 in high alumina brick is more than 60% .
Q:High alumina refractory bricks (Universal arc) weight for hot metal ladle
Climbing, C23B ladle generally use T3 ladle bottom brick, brick wall with C23 package, C231 Some permanent layers are built from high alumina bricks, and some are built from castable refractory, T82, T43. Specific size can be checked according to the type of brick
Q:Do refractory bricks need to be sent to the lab to test after arriving the site?
Generally speaking, as long as the use of temperature is not higher than 1500 degrees, it is not required to do the test, even if the ordinary refractory brick temperature is about 1500. If the temperature is high, then you do test to determine what kind of texture of refractory brick you need
Q:Do refractory bricks resist corrosion and sulfur?
There are anticorrosion and acid proof refractory bricks
Q:do the used refractory bricks pollute the environment?
the main pollution of refractory brick is coal gas pollution in the process of burning , it can be recycled to produce aggregate, waste brick has no pollution.
Q:what kind of refractory brick is suitable for 1300 degrees converter?
The furnace cap tapping shaft part should use MgO-C brick with high slag resistance and thermal shock resistance, the steel side can be slightly thin, bottom carbon content may be appropriate less.
Q:does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
Both needed! In fact, the insulation material contains refractory brick.
Q:General used refractory brick T-20 / T-39/ T-206 specifications and dimension
No T-206 model (we produce the clay) T-20 and T-39 are the size of 230*length, 113* width and 65/45 thickness, T-20 is a vertical arch brick and T-39 is horizontal arch brick.
