Product Description:

General information:

Cmax ceramic fiber blanket is made from high quality gao-ling clay, high purity alumina and silica oxides by spun or blown process. It is asbestos free. No chemical binder is added. Double-size needling provides blanket with great tensile or handling strength for easy installation. Blankets are available in various classified temperature from 1260ºC to 1430ºC.

Cmax ceramic fibre blanket is resistant to most chemicals attack except hydrofluoric phosphoric acid and high pH alkali(na2o or k2o). Its thermal and physical properties can not be affected by oil, steam and water, very good thermal insulating materials.

Advantages:
Heat reflectance
Light weight
Low thermal conductivity
Low heat storage
Flexible
Resilient to thermal stock
High tensile strength
Corrosion resistance
Easy to install
Asbestos free

Application:
Petrochemical process heater refractory fiber lining
Heat treating furnace or intermittent (shuttle) kiln hot face lining
General furnace backup insulation
Heat seals for kiln car or furnace door
Electrical insulator
High temperature acoustic
Fire protection

Non-standard sizes are available upon request.

Q:How to prevent high alumina refractory brick from producing crack when reproduce high alumina refractory brick?
1-1, on the 1 in order to prevent the emergence of crack in the production of high alumina refractory brick. 2 is appropriate, the water absorption rate of the tube mill should be controlled below 6%, the excess air coefficient controlled between level 1 and 2. The water absorption rate of clinker of bauxite with high alumina controlled under 4%-5%, making the high aluminum refractory brick burning in a smoothly and steadily weak oxidation atmosphere, and should be adjusted by thermotechnic
Q:What are the main raw materials of refractory brick and runner brick?
Types of refractory bricks are divided into low-grade and high-grade. generally, siliceous, semi siliceous and high aluminous runner brick brick have higher requirements. If it needs to contact melting in high temperature molten steel directly, then it is high alumina(the main raw material is clinker of bauxite with high alumina, corundum( brown corundum and white corundum), the refractoriness is high, lower than 1580 DEG C temperature, but the actual using temperature reaches 1630 DEG C
Q:can castable refractory replace refractory bricks in rotary kiln?
The heat produced in the welding process will cause local deformation of the rotary kiln, which will affect the dynamic balance, and the construction difficulty in the middle position of the rotary kiln is much larger than that of the refractory bricks. Moreover, the construction quality is not easy to ensure, generally only replace the refractory brick in the kilneye, because the construction of the castable refractory need to weld the anchor
Q:does furnace use refractory cement to make refractory bricks?
You can use fireclay, refractory cement is commonly used to arch. fireclay has good viscidity, it is handy to use.
Q:What is the meaning of the new type of dry rotary kiln refractory brick 620,320?
20 stands for that the length of the brick is 20CM, there is only a kind of 620 brick for masonry. Simply say: 1. 620 and 320 these two specifications of bricks are needed simultaneously if it is 4 meters kiln that should be built. When the diameter of the kiln is 6M. Other specifications of kiln can be built by useing these two kinds of bricks in different proportions. 3M kiln can be built only by using 320 brick, its proportion of use is 16. 3 stands for kiln's diameter
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:can the refractory sand be used to make refractory bricks?
yes, a lot of refractory sand is made by broken refractory brick, they have the same function.
Q:Is fireclay brick acidproof? Does clay brick anti corrosion when it's used to build chimney lining?
Refractory bricks anti acid and alkali after high-temperature calcination, and anti-corrosion won't be a problem
Q:1200 degrees inside the furnace, lay a layer of refractory brick, what is the temperature outside?
except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
Q:what is the ratio of refractory mortar and refractory bricks, such as how much refractory mortar is needed for a ton of refractory bricks?
Go to the refractory factory to buy some refractory clay that is of the same material as refractory bricks, generally boiler uses clay refractory mortar.
