The ceramic fiber module lining, as a light, efficient thermal insulation heat furnace, compared with the traditional refractory material lining, has the following technical performance advantages:
(1) Low -capacity ceramic fiber module lining is more than 70%lined with light heating tiles, 75%to 80% lighter than light pouring lining. It can greatly reduce the steel structure load of the kiln and extend the life of the furnace body.
(2) The thermal capacity of low thermal capacity furnace lining materials is generally proportional to the weight of the furnace lining. Low thermal capacity means that the kiln absorbs less calories in the reciprocating operation, and at the same time, the heating rate is accelerated. The thermal capacity of ceramic fiber is only 1/7 of the light heat -resistant lining and light clay tiles, which greatly reduces the energy consumption in the furnace temperature operation control. In particular, the heating furnace of intermittent operations can be very significant. energy saving effect.
(3) When the average temperature of the pottery fiber module is 400 ° C, the thermal conductivity coefficient is less than 0.11W/(m · k), the average heating coefficient is less than 0.22W/(m · k), when the average average 1000 ° C , Thermal conductivity is less than 0.28W/(m · k). About 1/8 of light -quality clay tiles, 1/10 of the light heat -resistant lining (pouring), the insulation effect is significant.
(4) The excellent ceramic fiber module of heat shock and mechanical vibration has flexibility, and has particularly excellent resistance to severe temperature fluctuations and mechanical vibrations.
(5) The construction is easy to solve the problem of slow installation speed in traditional modules. After the folding module is lifted in different directions, the folding module will not produce in different directions without gaps. The furnace lining does not require drying and maintenance, and can be used directly after installation.
At present, energy conservation, environmental protection, and preventing the earth’s warming have become the focus of attention from all over the world. The cost of fuel will become the bottleneck of the development of the steel industry. Therefore, people are more concerned about the heat loss of the industrial furnace. According to statistics, after the use of ceramic fiber modules for continuous industrial furnace kiln, the energy saving rate is 3%to 10%; It can reach 10%to 30%, or even higher.
The use of the lining of ceramic fiber modules can extend the life of the furnace kiln and reduce the loss of heat dissipation in the furnace body. The application of the crystal crystal ceramic fiber composite module of the new generation can not only improve the cleanliness of the furnace and improve the quality of the product, but also achieve better energy saving energy saving Effect.
Therefore, the heating furnace of the industrial furnace, especially the steel industry, should be used as a ceramic fiber module as the lining of the furnace when designing. Structure, this is also an important measure to achieve sustainable development of the steel industry.
