What Is Refractory Castable Used For?

In modern industrial production, high-temperature industrial kilns are indispensable. They play a key role in smelting and production. The construction of high-temperature kilns is inseparable from refractory castables. Its main function is to protect the inner wall of high-temperature equipment from high temperature, corrosion, and wear. It also has good thermal conductivity and mechanical strength. Today, the editor will take you to understand the use of refractory castables in high-temperature kilns in various industries.

In the metallurgical industry, refractory castables are often used for the lining of smelting equipment such as aluminum melting furnaces, open furnaces, alloy furnaces, converters, arc furnaces, and smelting furnaces. The use of refractory castables can protect the furnace walls and furnace bottoms that need to contact with high-temperature media and avoid high-temperature erosion and severe corrosion and wear. The use of refractory castables can effectively extend the service life of high-temperature smelting furnaces and improve production efficiency.

In the cement industry, in cement kilns, the temperature of clinker burning can reach hundreds of degrees Celsius or even higher, which places extremely high demands on the lining materials of the kiln. Using refractory castables as kiln linings can effectively reduce kiln wear and corrosion, extend the service life of equipment, and improve the quality and output of cement production.

In the glass industry, since the glass melt has a very high temperature and is highly corrosive to the furnace wall and furnace bottom, refractory castables with high refractory temperature and strong corrosion resistance are required to protect the furnace wall from high temperature and solution corrosion and ensure the stable production of glass.

In the chemical industry, refractory castables are used to manufacture the lining of high-temperature reactors. In addition to the need for refractory castables to resist high-temperature corrosion, refractory castables are also required to be acid-resistant or alkali-resistant to prevent chemical substances from corroding the reactor and ensure the safety and stability of the reaction process.

In the power industry, refractory castables are used to manufacture the linings of electric furnaces, kilns, and other equipment to cope with the working environment under high-temperature conditions and ensure the normal operation of the equipment.

In addition to the applications in the above industries, refractory castables are also widely used in aerospace, steel, coal, and other industries. By protecting the inner wall of the equipment from high temperature, corrosion, and wear, refractory castables can not only extend the service life of the equipment and improve production efficiency but also ensure the safety and stability of industrial production.
