Meanwhile, there are several types of Kerui refractory castables for sale, each suitable for specific applications and operating environments. The following are some common types of refractory castables.
High Alumina Refractory Castables
High alumina castables contain a high alumina content in their raw material composition, usually more than 60%. Besides, they have excellent refractoriness, thermal shock resistance and chemical stability. High alumina castables are suitable for severe conditions of use in the steel-making, petrochemical and cement industries.
Acid Resistant Refractory Castables
Acid resistant castables can withstand acidic environments and chemical attacks. Meanwhile, it is formulated with acid-resistant aggregates and binders. Moreover, they are used in industries containing acidic gases such as chemical plants, pickling tanks and acid storage areas to provide protection against corrosion and erosion.
Corundum Refractory Castables
Corundum castables consist of high purity corundum or flake alumina aggregates. In addition, castables have excellent high temperature properties with melting points in excess of 2000°C (3632°F). In addition, corundum castables are suitable for use in the steel-making, non-ferrous metals and petrochemical industries.
Wear-resistant Refractory Castables
Wear-resistant castables can withstand mechanical wear, erosion and impact in highly stressful environments. They contain high alumina or silicon carbide aggregates combined with suitable binders. Meanwhile, these castables become ideal materials for industries.
Mullite Refractory Castables
Mullite castables mainly consist of mullite crystals. Due to the high purity of the aluminum content in mullite castables, they have excellent thermal stability, low thermal expansion and high creep resistance. So they are usually used in industries with rapid temperature changes to estend equipment’s life.
Silicon Refractory Castables
Silicon carbide castables use silicon carbide as the main raw material. They have excellent thermal conductivity, wear resistance and chemical resistance. As a result, Silicon carbide castables are used in industries, such as waste-to-energy plants, the aluminum and copper industries and incinerators.
Insulating Refractory Castables
Insulating castables provide excellent thermal insulation and low thermal conductivity. They are lightweight and have a porous structure, which makes them ideal for applications where insulation is essential, such as kiln linings and flue lining. Besides, they are important refractory material for furnace maintenance.
Low Cement Refractory Castables
Low cement castables (LCC) have a lower refractory cement content than conventional castables. The lower cement content contributes to improved high-temp properties, increased strength and reduced porosity, which makes low cement castables suitable for use in areas of high mechanical stress and wear.
Unique Properties of Castable Refractory for Sale
Refractory castables offer a wide range of unique properties that make them indispensable in high temperature applications. Some of the key features include:
High-temp castable refractory can withstand extremely high temperatures, which makes them ideal for furnaces and other high-temperature equipment.
Some castables have excellent insulation properties to minimize heat loss and improve energy efficiency in heating applications.
The low porosity of refractory castables improves their resistance to gas, liquid and slag penetration. This extends the service life of the equipment.
Depending on their composition, refractory manufacturers castables are resistant to chemical attack and corrosion, which makes them suitable for use in acidic or alkaline environments.
Refractory castables have good mechanical strength, based on high castable refractory density. Furthermore, they maintain their structural integrity even under mechanical stress.
Because refractory castables cure quickly, they can be used for quick repairs and maintenance in industrial facilities. This helps to save construction time and increase efficiency.
Wide Applications of Refractory Castable for Sale
Refractory castables have a wide range of applications in high-temperature and corrosive industries. Besides, their unique properties make them the choice for a variety of industries. Some common applications for refractory castables include:
In cement kilns and preheaters, refractory castables are used as refractory linings to withstand extreme temperatures and chemical reactions. Meanwhile, insulating castables are also used in backup linings to conserve heat and improve energy efficiency.
In the ceramic industry, high-temp castable refractory is used in kilns and kiln cars for ceramic manufacturing. Because it has excellent thermal insulation and abrasion resistance, which can save energy costs and increase productivity in the ceramics industry.
Refractory castables are vital in the construction of crackers, reformers and boilers used in the petrochemical industry. Because the castables can resist corrosive gases and high temperatures ensure stable and efficient operation.
Refractory castables are widely used in steel furnace refractory such as blast furnaces, ladles, and intermediate ladles. So they can provide thermal insulation, slag resistance and protection against mechanical wear and corrosion.
High temperature castable refractory is suitable for kilns and converters in the aluminum, copper, and lead industries, for the reason that it has excellent thermal insulation properties and resistance to the corrosive properties of metal slags.
