Ceramic fiber is a type of high-temperature insulation material with low thermal conductivity. Nowadays, it is widely used in all kinds of industrial furnace systems, which has changed most furnace lining designs to an efficient, energy-saving, and high-temperature-resistant material.
Generally speaking, there are two types of bulk ceramic fiber manufacturing, one is called blowing ceramic fiber, which is made by breaking the high-temperature molten alumina and silica steam with compressed air. Another type is called spun ceramic fiber, which is made by dropping the molten alumina and silica on a fast-spinning disc. The bulk fiber can be used to made many kinds of shapes such as blankets, boards, textile, paper, modules, felt, coating, and so on. Blanket and board are the most popular and widely used shapes. They can be with a different density ranging from 64 kg/m3 to 180kg/m3 for the blanket, while 240 to 400 kg/m3 for the boards. Besides different sizes, temperature grades are available. As per customer request and the different applications, more than 45 types of different forms and converted products can be made from ceramic fiber blanket.
As their characters are a remarkable combination of the advantages of refractories and traditional insulation products. Below are some of the key points for reference to get the idea.
A. Low heat storage
Only 1-5% of the conventional furnace lining system will save energy much.
B. Light Weight
It is lighter than general insulation bricks, calcium silicate boards, thus it can support new type furnace structure design.
C. Lower thermal conductivity
Ceramic fiber insulation products can perform better than insulation brick and calcium silicate.
Block on the energy saving efficiency.
D. Easy to install
The ceramic fiber products are construction specifications standardized products with no
Special skills requested. This will be no risk of cracking or spalling when they are heated after installation.
E. Easy to handled by customers
F. Easy to maintain – The ceramic fiber with problems can be replaced or repaired much quickly with a minimal down time.
G. Mechanical resilience
This character makes the ceramic fiber furnace lining can be made off-site and then delivered to the construction site without damage.
H. Good thermal shock resistance – Furnace can be heated up or cooled down more faster to improve the industrial furnace productivity and efficiency.
I. Chemical resistance
