Low Cement Castable

Laurel Low cement castable is a high-quality unshaped refractory material. Compared with traditional castables, it significantly reduces the cement content. Superfine powders and other binders are used to replace part of the cement, which effectively reduces the pores generated by cement hydration and makes its structure denser. It not only has excellent high-temperature resistance, being able to easily cope with high-temperature industrial environments and maintain stability after being exposed to high temperatures for a long time, but also has good thermal shock resistance. When facing sudden temperature changes, it is not prone to problems such as cracking and spalling. Moreover, it shows strong mechanical strength and can withstand various external impacts during the operation of equipment. It is widely applied in high-temperature kilns and thermal equipment in many industries such as metallurgy, building materials, and power, providing a guarantee for their efficient and stable operation.

Low cement castables possess the following characteristics:


1. High Temperature Resistance: They can endure high temperatures, making them suitable for use in various high - temperature industrial furnaces, such as steel - making converters and cement rotary kilns.

2. Low Thermal Conductivity: With a relatively low thermal conductivity coefficient, they can effectively reduce heat loss, thus improving energy efficiency and reducing energy consumption.

3. Good Thermal Shock Resistance: They can resist the rapid changes in temperature without cracking or spalling, ensuring the stability and service life of the material.

4. High Strength: They have high compressive and flexural strength, which can withstand the mechanical stress and impact during the operation of the equipment.

5. Excellent Wear Resistance: They have good wear - resistant properties, which can resist the erosion of high - speed airflow, molten metal, and slag, thus prolonging the service life of the material.

6. Good Fluidity and Workability: They have good fluidity and workability, which can be easily poured and molded, and can be constructed into various shapes and sizes according to the needs.

7. Low Cement Content: The low cement content helps to reduce the amount of calcium aluminate hydrate formed during hydration, which can improve the high - temperature performance and durability of the material.

Low cement castables, with their remarkable properties such as excellent high-temperature resistance, thermal shock resistance, high strength, and good abrasion resistance and heat insulation, shine brightly in various key industrial fields. In the metallurgical industry, they serve as a solid safeguard for the stable operation of blast furnaces, converters, and electric furnaces, protecting crucial parts like the furnace body, inner linings, and furnace roofs. They resist the attacks of high-temperature molten iron, steel, and slag, reduce heat loss, and ensure the efficient progress of the smelting process. In the field of building materials, whether it is a cement rotary kiln or a glass kiln, low-cement castables can be found in various places such as the pool walls, breast walls, and inner linings. They help resist the scouring of materials and high-temperature erosion, improve the thermal efficiency of the kilns, and ensure the production of high-quality products. In the power industry, thermal power plant boilers and waste incinerators rely on them to strengthen the structures of the furnace chambers, flues, and inner linings, dealing with the scouring, corrosion, and abrasion of high-temperature flue gases, and achieving energy conservation, efficiency improvement, and environmental protection standards. In the chemical industry, cracking furnaces and gasifiers are inseparable from them. Parts such as the inner linings and furnace tube supports rely on them to withstand high temperatures, high pressures, and chemical corrosion, laying a solid foundation for complex and sophisticated chemical production processes and comprehensively promoting the development of various industries to a higher level.
