company news about Ultra-low Cement Refractory Castables

Ultra-low cement castables (ULCC) are a type of high-performance refractory material that is designed for use in high-temperature applications, such as in furnaces, kilns, and incinerators. ULCCs are characterized by their low cement content (typically less than 3%) and high alumina content, which makes them more resistant to thermal shock and abrasion than traditional castables.

The manufacturing process of ULCCs involves using high-purity raw materials, such as high-alumina aggregates, calcium aluminate cement, and other additives. The key features of ULCCs include:

1. Low porosity: ULCCs have a low porosity, which makes them more resistant to penetration by molten metal and slag.

2. High strength: ULCCs have high compressive and flexural strength, making them ideal for use in applications where resistance to mechanical wear and abrasion is critical.

3. Excellent thermal shock resistance: ULCCs are designed to withstand sudden changes in temperature, making them ideal for use in applications where the temperature fluctuates rapidly.

4. High refractoriness: ULCCs have a high melting point, typically above 1,500°C, which makes them ideal for use in high-temperature applications.

5. Good chemical resistance: ULCCs are highly resistant to chemical attack, making them suitable for use in harsh chemical environments

Ultra-low cement castables are typically installed using a casting or gunning process, which allows them to be applied quickly and efficiently to the desired area. They can also be customized to meet specific application requirements, such as varying levels of thermal conductivity or chemical resistance. Overall, ULCCs are a high-performance refractory material that offer excellent thermal and mechanical properties, making them ideal for use in a wide range of industrial applications.
