Zhengzhou Rongsheng Kiln Refractory Co., Ltd. (a National High-Tech Enterprise) has specialized in the research, development, and manufacturing of refractory materials for over 20 years. It offers high-quality, ultra-lightweight aluminate foam bricks designed specifically for high-end industrial, high-temperature environments. Utilizing alumina with a purity of ≥99%, these bricks can operate stably and long-term under extreme operating conditions of 1770–2000°C. With a thermal conductivity as low as 0.12 W/(m·K), they offer excellent insulation and significantly reduce energy consumption. Their unique hollow sphere structure reduces weight by over 30% while maintaining high strength and excellent thermal shock resistance, making them suitable for lining critical kilns in industries such as steel, cement, glass, and non-ferrous metals. Rongsheng utilizes automated intelligent production lines and is ISO9001 and CE certified to ensure consistent performance and reliable quality across each batch. Their products are exported to over 70 countries and regions across Europe, America, and Southeast Asia, making them a trusted international refractory supplier.
