China has solidified its position as a global leader in the production and export of refractory cement, a material indispensable in industries requiring high-temperature resistance and durability. Refractory cement is primarily used in constructing and maintaining furnaces, kilns, reactors, and other high-heat industrial equipment. The quality and composition of refractory cement directly influence the efficiency and longevity of these industrial processes. This article introduces the top 10 refractory cement manufacturers in China, focusing on their manufacturing capabilities, product offerings, and contributions to global industries. Topping the list is Dragon Abrasives Group Limited, recognized for its innovation, quality, and comprehensive product range.
Dragon Abrasives Group Limited, based in Zhengzhou, China, holds the premier position among refractory cement manufacturers in China. Since its establishment in 2013, the company has specialized in producing high-quality raw materials such as brown fused alumina, white fused alumina, zirconia alumina, and silicon carbide, which are crucial for refractory cement production. Dragon Abrasives' expertise extends beyond raw materials to delivering customized refractory cement products tailored to the specific requirements of global clients in steel, cement, and glass industries.
Their approach combines advanced manufacturing technologies with stringent quality control to ensure products meet international standards for strength, thermal resistance, and durability. Dragon Abrasives' substantial global market presence, servicing over 60 countries, underscores their role as a trusted partner in the refractory industry.
The manufacturing of refractory cement typically involves several key steps:
High-quality raw materials such as bauxite and lime are the foundation of refractory cement. These materials are carefully selected based on chemical composition and physical properties. The raw materials undergo crushing and grinding to achieve the desired particle size, enhancing the reactivity and strength of the final product.
The finely ground raw meal is subjected to preheating and calcination in rotary kilns at high temperatures. This process produces clinker containing calcium aluminate as the main component, with alumina content typically around 50%. The clinker formation is critical because it determines the cement's refractory properties.
The clinker is cooled, then ground into a fine powder with a specific surface area exceeding 300 m²/kg, which promotes rapid and adequate hydration reactions. During grinding, additives such as gypsum may be introduced to tailor the setting time and strength development of the cement.
Finished refractory cement is stored in silos and packed according to customer requirements. The finished products are shipped globally to support various industrial applications.
This comprehensive manufacturing process ensures refractory cement produced in China meets rigorous standards for fineness, early and late strength, chemical stability, and heat resistance.
Besides Dragon Abrasives, several prominent Chinese manufacturers contribute to the richness of the refractory cement industry. These companies include:
