Zhengzhou Rongsheng Refractory Co., Ltd., a national high-tech enterprise, has been deeply engaged in the research and development and production of refractory materials for over 20 years, launching high-quality high-alumina bricks. Made from high-quality bauxite with an Al₂O₃ content exceeding 48%, these bricks maintain structural stability and high strength even under extreme operating conditions of 1750–1800°C, making them particularly suitable for high-temperature furnace linings in the steel, glass, cement, and other industries. Their excellent resistance to acid and alkali slag effectively resists alternating erosion by acidic and alkaline slags, significantly extending the life of kilns. The products offer low thermal conductivity and excellent insulation, helping customers reduce energy consumption and improve energy efficiency. Rongsheng utilizes automated production lines, and each batch is certified by international certifications such as ISO9001, CE, and SGS to ensure consistent quality. With a global service network covering over 70 countries and regions, Rongsheng provides comprehensive support from pre-sales consultation to after-sales installation guidance, making it a trusted international provider of refractory solutions.
