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:The matching ratio of masonrying refractory bricks cement
Size of brickwork joint: Vertical and horizontal seam are 2 ~ 3 mm. The ratio of seam mud: Refractory clay mud 100%; per m3 dry, clean industrial water 400 ~ 600t/, no more than 3mm
Q:How to make the adhesion between refractory brick and the inner wall of the boiler more firm?
High temperature resistance can also extend its service cycle. If there are conditions for the user heat resistant steel welding nails. By using high temperature high alumina brick, expansion joints can not be too large, with high-temperature adhensive paste masonry, recommend that you use the refractory brick, add the amount of long pieces of brick or rachel brick
Q:Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?
They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem
Q:Red brick (solid clay brick) has been banned, why do few people know?
Because the brick hollow brick to heavy, made of the same height, weight heavier than the red brick building many hollow brick buildings, per unit area of the surface load is larger, directly lead to the design of building pile foundation, the column will also increase, lead to increased steel, cement and other building materials consumption, increase the cost of housing.
Q:The shape and size of general used refractory brick
240mm * 115mm * 53mm. and the width is 115mm, the shape and size of mechanism red brick is: 230mm * 114mm * 65mm, the outline dimension of special refractory brick is of 65mm thickness according to the national standard: Length is 230mm. That is: Length is 240mm. General type refractory brick's outline dimension is of 114mm width. That is, thickness is 53mm: 345*328*97
Q:what is consequence of high load and soft low of high alumina refractory brick ?
softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
Q:what should press on the heat preserving cotton above the suspended ceiling refractory brick ?
you can also put Z shaped steel on the purline, put heat preserving cotton on the roof boarding, it is easy to oprate.
Q:The form of boiler furnace wall
Q:How to adjust the temperature in the 160 meter tunnel kiln?
Tunnel kiln can be attemperated by burning products, this will not affect the firing of different products, and can burn back processing products.
Q:What are the simple ways to distinguish between excessive clay bricks and less fired clay bricks?
Refers to the internal combustion brick to save raw material and fuel in clay mixed with waste parts containing combustibles, such as coal cinder, coal gangue and fly ash, and make the fuel burning in a brick in the baking process, so as to obtain uniform calcination temperature and combustion, called by this method of roasting brick brick.
