Zhengzhou Rongsheng Kiln Refractory Co., Ltd. specializes in the development and production of high-alumina refractory bricks. These bricks utilize alumina content of 48%-80%, resulting in a bulk density of 2.1 to 2.7 g/cm³. These bricks maintain excellent thermal stability and mechanical strength even in high-temperature environments of 1420-1530°C. These bricks are resistant to high temperatures, chemical corrosion, thermal shock, and wear, making them widely used in linings of high-temperature kilns in the power, steel, non-ferrous metals, and petrochemical industries. Thanks to Zhengzhou Rongsheng's automated intelligent production line and comprehensive quality management system, each refractory brick is guaranteed to be dimensionally stable and structurally sound. The company also offers a wide range of customized services in terms of size, shape, and performance to meet diverse customer needs. Leveraging its strong R&D capabilities and global service network, Rongsheng is committed to becoming a trusted refractory expert in the international market, helping customers reduce maintenance costs and achieve long-term, stable equipment operation.
