What Are the Common Refractory Materials?
2023-11-27
Refractory materials are substances that can maintain stable performance under high-temperature conditions and are widely used in industries such as construction, metallurgy, petrochemical, aerospace, etc.
Refractory materials can be classified into the following categories based on their main components and properties:
1.Refractory Bricks: With alumina, magnesia, silicate, etc. as the main components, they have good heat resistance and thermal shock resistance and are widely used in furnace structures.
2.Refractory Castables: Composed of refractory aggregates, binders, additives, etc., they are often used for the repair and casting of furnace chambers, furnace bottoms, furnace doors and other parts.
3.Refractory Fibers: With alumina, silica, etc. as the main components, they have a relatively low thermal conductivity coefficient and can be used to make the thermal insulation layer of the furnace body.
4.Refractory Clays: Using clay, kaolin, etc. as the base materials, they can be used as binders for masonry and repair of refractory bricks.
5.Refractory Insulation Materials: Such as expanded perlite, aluminum silicate fiber, etc., which are mainly used for the insulation and heat preservation of high-temperature equipment.
