Ceramic Fiber Paper Ceramic Fiber Board Ceramic Fiber Blankets Ceramic Fiber Modules Advantages for Industrial Furnaces

At present, the monolithic ceramic fiber module obtained by compressing aluminum silicate ceramic fiber blankets is gradually becoming a modern industrial furnace lining with insulation and heat insulation, with its advantages of high temperature resistance and easy construction.

Over the past few years, the wide application of ceramic fiber paper, board, blankets and modules in petrochemical, steel, power, cement and other fields has enabled us to produce better thermal insulation products; one-stop service for technical support, material recommendation and quality tracking. , won the full recognition of the authoritative department and a wide range of industry reputation.

Application advantages:

1, the installation process, the ceramic fiber blanket is released after the binding will put great stress, crowding each sealed without leaving any gaps;

2, high elastic fiber blanket deformation can make the furnace shell, reduce construction costs. At the same time, it can make up for the gaps caused by different thermal changes of different components inside the furnace body;

3, due to the light weight, low thermal capacity (heat is only 1/10 of lightweight refractory brick lining and light), can significantly reduce energy consumption in the furnace temperature control operation;

4 , elastic fiber blanket can resist mechanical external force;

5 , has the ability to resist any thermal shock;

6, the lining of the body without drying and curing, lining construction is completed can be put into use;

7 , stable chemical properties. Except for phosphoric acid, hydrofluoric acid and strong alkali, other acids, alkalis, water, oil, and steam are not eroded.

Performance characteristics of ceramic fiber products

Ceramic fiber is currently a heat-insulating refractory material with low thermal conductivity and good thermal insulation and energy saving effect except for nano-materials. It has many advantages such as light weight, high temperature resistance, good insulation effect, convenient construction, etc. It is a high-quality industrial furnace lining material. Compared with traditional refractory bricks, refractory castables and other materials, refractory fiber materials have the following performance advantages:

a) Light weight (reducing kiln load and extending furnace life): Ceramic fiber is a fibrous refractory material, commonly used ceramic fiber blankets and ceramic fiberboards, blanket density of 96 ~ 128Kg/m3 , board density of 250 ~ 400Kg/m3 , and the volume density of the fire-resistant fiber modules folded by the fiber carpet is between 200 and 240 Kg/m3 , and the weight is 1/5 to 1/10 of the lightweight firebrick or amorphous material , which is heavy 1/15 to 1/20 of the refractory material . It can be seen that the refractory fiber lining material can realize the light and high efficiency of the heating furnace, reduce the load of the kiln furnace, and prolong the life of the furnace body.

b) Low heat capacity (less heat absorption, fast heating): The heat capacity of the lining material is generally proportional to the weight of the lining, and the low heat capacity means that the kiln absorbs less heat during the reciprocating operation, and at the same time, the temperature rises faster. The thermal capacity of ceramic fiber is only 1/10 of the lightweight heat-resistant lining and lightweight firebrick , which greatly reduces the energy consumption in the furnace temperature operation control, especially for the intermittent operation of the heating furnace, has a very significant energy-saving effect.

c) Low thermal conductivity (less heat loss): ceramic fiber material at an average temperature 200 ℃, thermal conductivity of less than 0.06W / mk, less than 0.10 W / mk average 400 ℃, about amorphous heat-resistant lightweight material 1 /8 , which is about 1/10 of light brick , and the thermal conductivity of ceramic fiber material and heavy refractories is negligible. Therefore, the thermal insulation effect of the refractory fiber material is very significant.

d) Construction is simple (no expansion joints are required): The construction personnel can go on the job after basic training. The construction technology has little effect on the insulation effect of the lining.

e) Wide range of use: With the development of refractory fiber production and application technology, fire-resistant ceramic fiber products have been serialized and functionalized, and the products can meet the requirements of different temperature levels from 600 °C to 1400 °C from the use temperature. . Forms have gradually formed from the traditional cotton, blankets, felt products to fiber modules, boards, special-shaped pieces, paper, fiber textiles and other forms of secondary processing or deep processing products. It can meet the needs of different industrial furnaces in different industries for the use of refractory ceramic fiber products.

f) Thermal Shock Resistance: The fiber folding module has particularly good resistance to severe temperature fluctuations. Under the premise that the heated material can withstand, the fiber folding module lining can be heated or cooled at any speed.

g) Resistance to mechanical vibration (flexibility and elasticity): The fiber blanket or felt is flexible and elastic, and it is not easily damaged. The installed whole furnace kiln is not easy to be damaged when it is impacted or transported by the road.

h) No oven required: No oven procedures (eg curing, drying, baking, complex oven processes and protective measures in cold weather) are required, and the lining can be put into service after construction.

I) Sound insulation performance (reducing noise pollution): Ceramic fibers can reduce high-frequency noise with a frequency of less than 1000 Hz . Sound waves less than 300 Hz have better sound insulation than common sound insulation materials, which can significantly reduce noise pollution.

j) Strong automatic control capability: The high thermal sensitivity of the ceramic fiber lining is more suitable for automatic control of the heating furnace.

k) Chemical stability: The chemical properties of ceramic fiber lining are stable. Except for phosphoric acid, hydrofluoric acid and alkali, other acids, alkalis, water, oil and steam are not eroded.

In addition, ceramic fiber paper and special-shaped pieces also play a significant role in the sealing and heat insulation of industrial kilns, and are widely used in electrical and petrochemical industries. In combination with ceramic fiber blankets and plates, the thermal insulation function can be utilized. Help you save energy and protect the environment.
