The refractory fiber also known as ceramic fiber, the present, except nanomaterials, the lowest thermal conductivity, thermal insulation energy-saving effect of the best refractory. It has light weight, high temperature resistance, good insulation effect, convenient construction and many other advantages, quality industrial lining material.

Refractory fiber materials with traditional refractory bricks, refractory castable materials, with the following performance advantages:

light weight (reducing furnace load, and to extend the life of the furnace): a) the fire-resistant fiber is a fibrous refractory material, the most commonly used refractory fiber blanket, a bulk density of 96 to 128kg/m3 and the use of fiber blanket made ​​by folding refractory fiber modules bulk density in the range of 200 to 240 Kg/m3, weight is the lightweight bricks or unshaped material 1/5 to 1/10, heavy refractory 1/15 to 1/20. Refractory fiber lining material can be seen, the light of the furnace, efficient, reduce the burden on the furnace, to extend the life of the furnace.

b) heat capacity (less heat, heating up fast): the heat capacity of the lining material is generally proportional to the weight of the lining of the low heat capacity means that the furnace heat absorbed by a reciprocal operation, while warming faster. The thermal capacity of the ceramic fiber is a lightweight heat-resistant lining and lightweight refractory bricks only 1/10, greatly reduces the energy consumption of the furnace operation control, especially for the intermittent operation of the furnace, having a very significant energy saving effect.

c) low thermal conductivity (heat loss): ceramic fiber material in the average temperature of 200 ° C, the thermal conductivity of less than 0.06W/mk, an average of 400 ° C is less than 0.10 W / mk, approximately lightweight heat-resistant monolithic materials 1/8, 1/10 of the light brick, ceramic fiber material with heavy refractory thermal conductivity by contrast, can be negligible. Fibrous refractory insulation effect is very significant.

d) the construction is simple (without leaving in expansion joints): construction workers basic training posts, the construction technical factors lining insulation effect.

e) the use of a wide range of refractory ceramic fiber products has been achieved: With the development of refractory fiber production and application technology, a series of functional products from the use of temperature from 600 ° C to 1400 ° C temperature grade meet requirements . The form has evolved from the traditional cotton, blankets, carpets products to fiber modules, boards, shaped pieces of paper, fiber textiles and other forms of secondary processing or deep processing products. Meet the various needs of different industrial furnace refractory ceramic fiber products.

f) thermal shock: the fiber folding module dramatic temperature fluctuations having particularly excellent resistance properties in the heated material can withstand, under the premise, the the fiber folding module lining can be arbitrarily fast heating or cooling.

g) resistance to mechanical vibration (flexible and elastic): fiber blanket or felt with flexible and elastic, and not easy to break, not easily damaged by shock or vibration of road transport overall furnace installation is completed.

h) without oven: no oven program (such as: conservation, drying, baking, complex process oven and cold weather protection), the lining construction has been completed ready for use.

I) noise performance (noise pollution): ceramic fiber can reduce high-frequency noise frequency is less than 1000 Hz, less than 300HZ acoustic, sound insulation is better than the commonly used sound insulation materials, can significantly reduce noise pollution.

j) automation and control ability: ceramic fiber lining in high heat-sensitive, can adapt to the automated control of the furnace.

k) chemical stability: stable chemical properties of the ceramic fiber lining, phosphoric acid, hydrofluoric acid and alkali, acid, alkali and water, oil, steam is not eroded.
