In metallurgical industry, aluminum silicate fiber blanket, as an efficient thermal insulation material, is widely used in a variety of high-temperature equipment. Its thermal insulation principle and application mode are as follows:

I. Thermal insulation principle

Low thermal conductivity: The aluminum silicate fiber blanket has a very low thermal conductivity (usually between 0.04 and 0.12 W/m k), which can effectively prevent heat transfer and thus reduce heat loss.

High heat resistance: its temperature resistance ranges from 800℃ to 1600℃, and it can maintain stable physical properties in high temperature environment without deformation or damage due to high temperature.

Good chemical stability: the aluminum silicate fiber blanket has excellent chemical erosion resistance and can resist chemical media in high temperature environment.

II. Specific application in metallurgical industry

Wall and roof of high temperature furnace: aluminum silicate fiber blanket is widely used for heat insulation of wall and roof. Its low thermal conductivity and high heat resistance can effectively reduce heat loss and improve energy utilization efficiency.

Heating furnace and heat treatment furnace: in heating furnace and heat treatment furnace, aluminum silicate fiber blanket can be used as lining and backing material, which plays the role of heat insulation, heat preservation and fire prevention.

Ladle and tundish: In the heat insulation of ladle and tundish, aluminum silicate fiber blanket can effectively reduce heat loss and improve the temperature stability of molten steel.

Pipe insulation: used for heat insulation of high-temperature pipes to reduce heat loss during transportation and prolong the service life of pipes.

Furnace door and cover: Aluminum silicate fiber blanket can be used for heat insulation and sealing of furnace door and cover to prevent heat leakage and improve the sealing and heat insulation effect of furnace body.

III. Application advantages

Energy saving and consumption reduction: through effective heat insulation, reduce heat loss and improve energy utilization efficiency.

Extend the service life of equipment: reduce the erosion of equipment by high temperature and reduce the maintenance cost of equipment.

Convenient construction: the aluminum silicate fiber blanket is lightweight and easy to cut and install.

To sum up, aluminum silicate fiber blanket has played an important role in the metallurgical industry, and its excellent performance has effectively improved the efficiency and safety of industrial production.
