Application scope of refractory classification

2024-06-26

Refractory is an important industrial material, which is mainly used in construction, metallurgy, chemical industry and other fields under high temperature environment. According to their properties and applications, refractory materials can be divided into many types and are widely used in various occasions.

Classification of 1. refractories

1. Clay refractories: clay as the main raw material, with good plasticity, refractoriness and chemical stability, mainly used in blast furnaces, hot stoves and other thermal equipment.
2. Siliceous refractories: silica as raw material, with high temperature strength, corrosion resistance and good thermal stability, widely used in glass, ceramics and other industries.
3. High alumina refractory material: high bauxite as raw material, with excellent refractory performance and slag resistance, mainly used in steel industry furnace.
4. Magnesia refractories: magnesium minerals as raw materials, with excellent high temperature resistance and chemical stability, used in smelting non-ferrous metals and special ceramics and other fields.
5. Other refractory materials: such as silicon carbide, silicon nitride and other special refractory materials, with unique high temperature performance and special purpose.

Application range of 2. refractories

1. Construction industry: refractory bricks, refractory cement, etc. are used to build high-temperature furnaces, such as glass furnaces, ceramic firing kilns, etc.
2. Metallurgical industry: Refractory materials play a key role in the smelting process of steel and non-ferrous metals, such as the lining materials of blast furnaces and converters.
3. Chemical industry: used for high temperature reaction kettle, heat exchanger, petrochemical equipment lining materials, etc.
4. Power industry: Refractory concrete and refractory bricks are used to build boilers, chimneys and other high-temperature parts of thermal power plants.
Other fields: such as ceramics, glass and other industries, refractory materials are also essential raw materials.

In addition, with the advancement of science and technology, some new refractory materials such as ceramic fibers and nano-refractory materials have gradually emerged and are widely used in high-tech fields such as aerospace and new energy vehicles.

In short, refractory materials are widely used in many fields, which is of great significance for improving the service life of equipment and ensuring production safety. With the continuous development of industrial technology, the requirements for the performance of refractory materials are also increasing, and the research and development of refractory materials will be more in-depth in the future.
