Ceramic fiber blankets are widely used in metallurgical industry, mainly in the following aspects:

I. Thermal insulation of high-temperature furnace lining

Ceramic fiber blankets are widely used in the lining of metallurgical furnaces, such as electric arc furnaces, soaking furnaces and heating furnaces. Its excellent thermal insulation performance can significantly reduce heat loss and improve energy utilization efficiency. For example, in the steel reheating furnace, ceramic fiber blanket can be used as a backup heat insulation material behind refractory bricks, which can effectively reduce the surface temperature of the furnace body. In addition, ceramic fiber blanket can also be used for heat insulation of ladle cover to reduce the heat loss of molten metal during transfer.

II. Furnace insulation

In metallurgical industry, ceramic fiber blanket can be used as the lining of steel, aluminum, copper and other metal furnaces, which can withstand high temperature environment and provide good heat insulation effect. Its low thermal conductivity and high tensile strength make it still stable in high temperature environment.

III. Heat preservation of heat treatment furnace

Ceramic fiber blankets are also widely used in heat treatment furnaces (such as annealing furnaces and tempering furnaces). It can provide a stable high temperature environment and ensure the uniformity and efficiency of the heat treatment process. Its good thermal shock resistance enables it to adapt to the rapid change of temperature and prolong the service life of the equipment.

IV. Thermal insulation of high-temperature pipelines

In metallurgical industry, heat insulation of high-temperature pipeline is the key to ensure energy efficiency and operation safety. Ceramic fiber blanket can be used to wrap high-temperature pipelines, reducing heat loss and protecting pipelines from high-temperature corrosion.

V. Furnace wall insulation

Ceramic fiber blanket can be used for the insulation layer of furnace wall, and its light and soft characteristics are convenient for installation, which can effectively reduce the weight of furnace and provide excellent heat insulation effect. Compared with traditional refractory bricks, ceramic fiber blankets are more convenient to install and have higher thermal shock resistance.

VI. Energy Conservation and Environmental Protection

The use of ceramic fiber blanket can significantly reduce the energy consumption in metallurgical industry. For example, in an aluminum smelter, after replacing the traditional thermal insulation materials with ceramic fiber blankets, the energy-saving effect can reach 25% and the service life can be as long as 8 years. In addition, the low thermal conductivity and high thermal insulation of ceramic fiber blanket are helpful to reduce greenhouse gas emissions and meet the requirements of environmental protection.

VII. High temperature sealing

Ceramic fiber blanket can also be used for sealing high-temperature equipment, such as furnace door sealing of kilns and boilers. Its good chemical stability and corrosion resistance enable it to be used in high temperature environment for a long time.

VIII. Summary

Ceramic fiber blanket has obvious application advantages in metallurgical industry, including excellent heat insulation performance, high temperature stability, thermal shock resistance and chemical stability. It can not only improve the energy utilization efficiency and reduce the production cost, but also prolong the service life of equipment and ensure the safety of operation.
