This high-performance refractory material is an ideal solution for the installation, repair, and maintenance of furnace linings in a wide range of industrial kilns.
I.Composition and Key Characteristics
Silicon carbide corundum refractory plastic is a high-performance unshaped refractory material formulated with premium white corundum and high-purity silicon carbide aggregates. Enhanced with ultrafine additives, high-temperature binders, and plasticizers, it delivers excellent workability, outstanding wear resistance, and long-term stability in demanding high-temperature applications.
The combination of corundum and silicon carbide provides exceptional mechanical strength, abrasion and corrosion resistance, thermal shock stability, and reliable performance under severe service conditions. Compared with conventional refractory plastics, it offers a longer service life and lower maintenance requirements, making it an ideal choice for wear-resistant furnace linings in a wide range of industrial kilns.
II. Key Product Advantages
Compared with conventional high-alumina refractory plastics and wear-resistant castables, our silicon carbide corundum refractory plastic delivers superior performance under demanding operating conditions. It is designed to minimize common problems such as furnace lining wear, erosion, corrosion, and frequent maintenance, helping extend lining service life and improve operational reliability.
1. Superior Wear and Corrosion Resistance for Longer Service Life
Our silicon carbide corundum refractory plastic features a dense microstructure and high hardness, providing outstanding resistance to abrasion and corrosion at elevated temperatures. Even under continuous service at temperatures of up to 1,100°C, it demonstrates very low wear loss and offers more than 40% higher wear resistance than conventional refractory materials.
The material effectively withstands abrasion from high-temperature bulk materials, chemical attack from flue gases, and particle erosion. By reducing lining wear, premature failure, and spalling, it helps extend furnace lining service life, minimize maintenance downtime, and improve overall operating reliability.
2. Excellent Thermal Shock and Spalling Resistance
Our silicon carbide corundum refractory plastic is engineered for demanding high-temperature operating conditions and offers excellent refractoriness and thermal stability. It maintains its structural integrity without softening or deformation, even during prolonged exposure to elevated temperatures.
The material provides outstanding resistance to thermal cycling, effectively resisting cracking and spalling during frequent kiln start-up and shutdown cycles as well as rapid temperature fluctuations. Its excellent high-temperature stability makes it an ideal choice for continuous industrial operation, helping ensure reliable furnace performance and longer lining service life.
3. Excellent Workability and Installation Flexibility
Our silicon carbide corundum refractory plastic offers excellent plasticity and adhesion at ambient temperature, with a uniform, fine texture that allows for easy ramming and shaping without the need for complex formwork.
The material readily conforms to irregular furnace linings and equipment geometries, making it ideal for repairing corners, joints, worn areas, and other hard-to-reach sections. Its outstanding workability enables efficient installation in a wide variety of non-standard industrial equipment and complex lining configurations.
4. Fast and Efficient Installation
Our silicon carbide corundum refractory plastic is easy to install and requires only minimal mixing and on-site preparation. After ramming and shaping, it requires no lengthy curing process and can be returned to service quickly, helping reduce installation time, labor requirements, and maintenance costs.
The material is suitable for a wide range of applications, including emergency repairs, routine maintenance, and new furnace lining installations. In addition, its controlled high-temperature expansion helps fill installation gaps, improving lining integrity and ensuring a tight, reliable seal during operation.
5. Reliable Performance in Harsh Operating Conditions
Our silicon carbide corundum refractory plastic is chemically stable and offers excellent resistance to acidic and alkaline environments as well as high-temperature oxidation. It maintains consistent performance under severe operating conditions involving abrasive materials, erosion, corrosive atmospheres, and elevated temperatures.
With excellent chemical stability and durability, the material minimizes performance degradation in demanding industrial environments, making it suitable for a wide range of high-temperature applications in the steel, cement, power generation, and other heavy industries.
III. Typical Applications
With its outstanding mechanical strength, wear resistance, and thermal stability, silicon carbide corundum refractory plastic is widely used in power generation, steelmaking, metallurgy, cement production, chemical processing, and waste incineration. It is an ideal refractory material for the installation, repair, and maintenance of high-temperature, wear-resistant linings in industrial furnaces and thermal processing equipment.
