Ceramic fiber board has been widely used in industrial furnaces because of its excellent heat insulation performance, high temperature resistance and lightweight design. The following are the specific applications and performance advantages of ceramic fiber board in industrial furnaces:

I. lining of high temperature furnace

As the lining material of industrial furnaces, ceramic fiber board can effectively reduce heat loss and improve energy utilization efficiency. Its low thermal conductivity (usually 0.04-0.08 W/(m k)) and high temperature resistance (up to 1350℃ or even higher) make it an ideal thermal insulation material. For example, in the soaking pit of iron and steel industry, using ceramic fiber module as the insulation layer of furnace wall and roof can significantly reduce the surface temperature of furnace body, reduce heat loss and reduce energy consumption by about 15%.

II. Heating furnace insulation

In the heating furnace, ceramic fiber board is used as the heat insulation layer of the furnace wall and roof, which can effectively reduce energy consumption. Its lightweight design reduces the self-weight of the furnace body and the requirements for steel structure, thus reducing the engineering cost. For example, after ceramic fiber board was adopted in a steel plant, the energy consumption of heating furnace was reduced by 15%.

III. Glass melting furnace

The glass melting furnace needs to run at high temperature for a long time. ceramic fiber board can effectively reduce the surface temperature of the furnace body, reduce the radiation of heat to the workshop environment and improve the working environment. At the same time, the improvement of heat insulation effect improves the energy utilization efficiency of melting furnace by about 20%, and reduces the production cost.

IV. Insulation of annealing furnace

In the glass annealing furnace, ceramic fiber board, as a heat insulation material, can effectively control the annealing temperature and improve the product quality. After ceramic fiber board was adopted in a glass factory, the energy consumption of annealing furnace was reduced by 10%.

V. Thermal insulation of high-temperature pipelines in petrochemical industry

Ceramic fiber board is used for high-temperature pipeline insulation in petrochemical industry, which can effectively prevent heat loss and excessive pipeline surface temperature, and has strong chemical corrosion resistance and can resist harsh chemical environment.

VI. Other high-temperature applications

Ceramic fiber board can also be used for high-temperature equipment in iron and steel smelting, electric power, nuclear industry and other fields, providing efficient thermal isolation and thermal insulation protection.

VII. Performance advantages

Low thermal conductivity: The thermal conductivity of ceramic fiber board is much lower than that of traditional refractories, and the thermal insulation effect is remarkable.

High temperature stability: it can be used for a long time in the high temperature environment of 1000℃-1600℃.

Lightweight: Compared with traditional refractory bricks, ceramic fiber board is light in weight and easy to install, which can significantly reduce the equipment load.

Thermal shock resistance: able to withstand the rapid change of temperature and not easy to be damaged.

Chemical stability: excellent corrosion resistance to most chemicals.

VIII. Summary

With its excellent heat insulation performance, high temperature resistance and lightweight design, ceramic fiber board has shown great application advantages in industrial furnaces. It can not only significantly reduce the energy consumption of furnaces, but also improve production efficiency and reduce environmental pollution. With the continuous progress of technology, ceramic fiber board will be more widely used in industrial furnaces, providing strong support for the sustainable development of industrial production.
