Product Description:

FUSED CAST BRICK

 

CMAX Bricks made from high quality quartz tail sand, lime and mineralizing agent through the process of crashing, screening, mixing, pressing, drying and sintering.

 

Application


CMAX Silica bricks are commonly applied in coke oven, hot blast stoves, glass furnace etc.

 

Advantage

 

Fused cast AZS (alumina, zirconia and silica) firebricks are mainly categorized into 33#, 36# and 41# according to different zirconia's contents from 33% to 41%.
Fused cast alumina (α-β Al2O3 and β Al2O3) firebricks are composed of alpha alumina, beta alumina and small amount of glass phase.

Both AZS and alumina firebricks have shown excellent performance in glass furnace construction.

Q:What is the perservation method for refractory bricks used for cement kiln?
The place should be dry and ventilated. Remember that the packaging can't be damaged. If is not used for a long time, put desiccant next to the bricks. Then have thermoplastic packaging again, it won't get damp. Under normal circumstances, it can be stored for 3-5 years and won't be hairy
Q:What is the raw material for the production of refractory bricks?
Mainly Magnesium Oxide, use sodium silicate as a binder.
Q:When using high alumina refractory brick, what are the reasons leading to the decline of the performance of high alumina brick?
The excess air coefficient is controlled in 1, in order to prevent producing water cracks in the production of high aluminum refractory brick from, control the water absorption of 2 grade clinker of bauxite with high alumina below 4%-5%. 1-1,the water absorption of the tube mill should also be controlled below 6%, and adjust thermotechnical, making the high alumina refractory brick burning be in the stable weak oxidizing atmosphere. should be 2
Q:how heavy are boiler of six tons plus refractory bricks?
The total weight is about 60 tons, 6 tons of bulk boiler steel, insulation materials, sealing materials, refractory material
Q:MU10 what are the non clay solid bricks?
Mu10 is the strength grade of bricks, divided into grades MU7.5, 10, 15, 20, 25, 30 and so on. Non clay brick "non sintered clay bricks, such as sand brick, shale brick, cement brick, fly ash brick etc..
Q:Why is the brick instead of solid clay brick
Shale has the characteristics of high temperature resistant, is fire gangwa, pottery, porcelain power the best materials, especially shale burning system with shale brick is a new type of environmentally friendly building materials, has become the main building material to substitute for clay brick, high economic and social benefits, the market prospect is broad, is the best raw material for production of high hollow brick wall the quality of the.
Q:Can refractory bricks be used to build a house?
Refractory brick can be used to build houses, but you can not use ordinary cement to build, the cost is 3 times than that of ordinary brick.
Q:Do refractory bricks insulate heat?
It can not be generalized, generally, the insulation performance of clay is not good, but the hollow is good, such as light mullite bricks have good insulation. it depends on what kind of refractory brick
Q:What are the differences between fired brick and clay brick?
. Sintered brick is mainly different from cement bricks and so on, not burning bricks at high temperature. Clay fired brick is widely used in paving roads, pavements and clean walls.
Q:can the red brick be used as refractory brick?
Can not replace! The high temperature will make it burst. Coefficient of thermal expansion is not enough
