Ceramic fiber module is widely used in metallurgical industry, which is mainly used to improve the thermal insulation performance of furnace lining, reduce energy consumption, reduce heat loss and prolong the service life of furnace body. The following are the specific applications of ceramic fiber modules in metallurgical industry:

I. Thermal insulation of ladle cover and ladle

Ceramic fiber module is used in the heat insulation layer of ladle cover and ladle, which can effectively reduce heat loss and improve energy utilization efficiency. Its low thermal conductivity and good thermal insulation performance can significantly reduce the surface temperature of the inclusion and reduce the heat conduction to the outside.

II. Furnace walls of heating furnace and heat treatment furnace

In heating furnace and heat treatment furnace, ceramic fiber module is widely used in the thermal insulation layer of furnace wall. Its modular design is convenient for rapid installation and can resist thermal shock and chemical corrosion in high temperature environment. In addition, the elasticity of the module can make up for the deformation of the furnace shell and ensure the integrity of the insulation layer.

III. Roof and ceiling

Ceramic fiber modules are also widely used in furnace tops and ceilings. Its light weight and low thermal conductivity make it an ideal thermal insulation material, which can effectively reduce the heat loss of the furnace top and improve the thermal efficiency in the furnace. For example, in the ceiling of brick-burning tunnel kiln, the excellent thermal insulation performance of ceramic fiber module is highly praised.

IV. Coke can cover

Ceramic fiber module is also used for thermal insulation of coke tank cover, which can effectively reduce the heat loss of coke tank in high temperature environment and protect the coke tank structure from high temperature erosion.

V. Other high-temperature equipment

Ceramic fiber module can also be used for heat insulation of other high-temperature equipment, such as billet carrier and forging furnace. Its excellent thermal insulation and thermal shock resistance enable it to run stably in high temperature environment for a long time.

VI. Installation method

The installation process of ceramic fiber module is relatively simple, mainly including the following steps:

Derusting: Before construction, the steel plate on the furnace wall should be derusted to ensure the welding quality.

Welding anchor pieces: according to the design requirements, weld anchor bolts on the steel plate of the furnace wall and protect the threaded part of the bolts.

Coating high-temperature anticorrosive coating: coating high-temperature anticorrosive coating on the steel plate and bolt root of the furnace wall.

Installation of modules: ceramic fiber modules are fixed on the furnace wall through anchors, and the modules will squeeze each other after expanding in the compression direction to form a seamless whole.

VII. Advantages

Low thermal conductivity and low thermal capacity: ceramic fiber module has excellent thermal insulation performance, which can significantly reduce heat loss.

High-temperature stability: the module can remain stable in high-temperature environment and resist thermal shock.

Easy installation: Modular design is convenient for quick installation, and there is no need for on-site cutting or shaping.

Environmental protection and energy saving: it conforms to the national energy saving and emission reduction policy and helps to reduce energy consumption.

To sum up, the application of ceramic fiber module in metallurgical industry not only improves the thermal insulation performance of furnace lining, but also reduces energy consumption and maintenance cost, so it is an ideal thermal insulation material in metallurgical industry.
