Characteristics of amorphous refractories
High refractoriness: Most of the raw materials of amorphous refractories have high refractoriness and can be used at extremely high temperatures. They are suitable for high-temperature industrial environments such as metallurgy, chemical industry, and electricity.
Excellent thermal stability: They can withstand environmental changes such as thermal shock and thermal cycling at high temperatures and are not easy to break or deteriorate.
Higher mechanical strength: Raw materials such as high aluminum and corundum make amorphous refractories have good compressive strength and impact resistance.
Convenient construction: Compared with traditional refractory bricks, amorphous refractories are more flexible in construction and can adapt to equipment with complex shapes. When using, you only need to pour, spray, lay or repair the mixed materials, which reduces the difficulty of construction.
Strong customizability: Amorphous refractories can adjust the composition ratio and performance according to specific application requirements to meet special requirements, such as oxidation resistance, corrosion resistance, and permeability resistance.
Economical: Amorphous refractories reduce the difficulty of splicing and construction of brickwork during construction, thus saving manpower and material costs to a certain extent.
Easy maintenance: Since amorphous refractory materials are often used in the lining of equipment, local maintenance or renewal can be easily carried out after the service life expires.
Application fields of amorphous refractory materials
Metallurgical industry: The lining, furnace mouth, furnace bottom, furnace cover and other parts of blast furnaces, converters, electric furnaces, and steelmaking furnaces require high temperature resistance, impact resistance, wear resistance and other characteristics.
Steel industry: In the process of steel smelting, amorphous refractory materials are used in casting pouring systems, ladle linings, heating furnaces, etc.
Cement industry: In cement production, especially in the construction and repair of linings of equipment such as kilns and preheating towers.
Glass industry: The linings of glass melting furnaces, glass kilns, hot blast furnaces, etc. require materials to have excellent high temperature resistance and chemical corrosion resistance.
Chemical and petroleum refining industries: Refractory protection and anti-corrosion treatment of equipment, pipelines and storage tanks.
Other high-temperature industries:
In fields such as ceramics, casting, and mechanical industries, amorphous refractory materials are often used in high-temperature parts such as kilns, furnaces, and combustion chambers.
Summary
Amorphous refractory materials are widely used in many industries such as steel, metallurgy, glass, and chemical industry due to their flexible construction, strong adaptability, and good high-temperature performance. With the advancement of technology, modern amorphous refractory materials are constantly innovating in composition, performance, and construction technology, and can meet more and more application needs under high temperature and special working conditions.
When selecting amorphous refractory materials, reasonable material selection and proportioning should be carried out according to multiple factors such as the use environment, temperature requirements, and material properties to ensure maximum performance.
