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 much fireclay is needed for 10000 refractory bricks?
The amount of mud used for T-3 refractory brick is 0.3KG. if the tiler is skillful, the furnace should have joint of 2mm.
Q:What is the relationship between the firing process and the manufacturing technique of fireclay bricks?
Q:What is the meaning of the new type of dry rotary kiln refractory brick 620,320?
It should be the length of the turn. I'm not sure if it is right.
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:How to do refractory bricks
There are many varieties of refractory bricks, and the pratice of it is similar to ordinary brick practice, but the requirements of equipment and technology will be much higher
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:The renewal of refractory brick internal the lime kiln belongs to overhaul. In the absence of production, are the replacement of valve and sporadic projects also considered overhauls? Or routine maintenance!
The replacement of fire brick is a major overhaul. If the part causes the furnace shutdown, which is also a major overhaul, so the key of overhaul is depends on what reason it is
Q:is there any requirement for radioactive materials in refractory materials.
they all do not cause radiological hazards to the environment, so no requirements! analyze rom the element , magnesia. Do not know if it is useful, but material used by refractory materials, firstly any chemical elements are radioactive, human beings can not close, then, such as silicon dioxide: If it is radioactive. analyze from use, such as bauxite, does not have the use value
Q:Small size black brick can replace refractory bricks for wood burning fireplace?
No. Because black brick has no fireproof function. The result of using the black brick can only be counterproductive, and which is also a waste of time and fuel.
Q:how to test the high alumina refractory brick mixed alumina?
Test
