Product Description:

General Information

CMAX insulating firebricks are classified under temperature between 1300℃ to 1700℃, manufactured from high purity alumina clay.

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 sintering, which meets the requirement of construction.
5. Max service temp: Up to 1730C (3160F)

 

Feature
Light weight and low thermal conductivity    
Low heat storage  
Low iron and impurities  
High thermal shock resistance

 

Application
CMAX insulating firebricks can be used as a hot face lining directly exposed to the heat or as a backup insulation layer in iron and steel mills, non-ferrous foundries, petrochemical, ceramic, glass.

Q:What are the types of building blocks?
1. the use of the different parts, building bricks into bricks, floor brick, brick, brick arch shell, brick brick chimney and sewer.2. different building performance, building bricks into bearing brick, brick, brick, non bearing engineering insulation brick, brick, tile, acoustical tile and other flowers.The use of 3. different materials, is divided into building brick clay brick, shale, coal gangue brick, fly ash brick, slag brick, lime sand brick etc..4. according to the shape, the building brick can be divided into solid brick, microporous brick, porous brick and hollow brick. Ordinary bricks and special-shaped bricks, etc..
Q:Is the quality of brick made of small-sized self insulation block equipment the same as that of large block brick equipment?
Recently, a lot of people have encountered this problem, Silver Horse understand, in fact, the brick machine is only the production of different production, the quality of the bricks produced are the same.
Q:What kind of material is clay insulation refractory brick made of?
Alumina silicate refractories with a content of 30% ~ 46% are called clayey refractories. Clay products are mainly made of mullite, glass phase, square quartz and quartz.
Q:How shall the sintered porous self insulation bricks be laid at the bottom of the beam?
All reserved holes larger than 200 * 200 shall be reserved
Q:What is the difference between the production line of foamed cement insulation bricks and the self thermal insulation block production line?
I still feel that the special is better, specializing in the production of a product, at least quality and after-sale protection!
Q:The difference between ordinary and diatomite brick refractory brick?
Refractory brick belongs to a large class, according to different materials used are divided into: high alumina brick, dolomite brick, magnesia chrome brick, magnesia spinel brick, phosphate brick, carborundum brick, brick, mullite bricks etc..
Q:What are the improvements and improvements during the trial production of insulating bricks?
Insulation brick seven characteristics: insulation, heat insulation: effectively reduce energy consumption.Fire prevention: up to national standard or class A.Clean and environmental protection: no two pollution will be caused by air.
Q:Does the building with the exterior wall thermal insulation brick require adding an angle steel bracket in the middle of the brick?
The first thing the man has to do is to do the quality test in front of the wall. As for the second, there is not much to do.
Q:Refractory bricks, burner bricks, insulation bricks? Is it a kind of thing?
The burner brick is heavy brick, the use temperature is higher, the insulating brick is light brick, the use temperature is lower than the heavy brick.
Q:What is a heat insulating brick?
The insulation brick integrates the excellent heat preservation effect into the wall while building the wall. Low thermal conductivity, high strength, strong durability, simple construction, light weight, easy loading and unloading, economic, green, environmental protection, sound insulation, fire protection and so on.
