Zhengzhou Rongsheng Kiln Refractory Co., Ltd. offers high-quality fused corundum bricks designed specifically for extreme high-temperature conditions such as steelmaking ladles. They offer a refractoriness of up to 1770°C to 2000°C and possess excellent thermal shock resistance and mechanical strength. Crafted from premium corundum raw materials, these bricks can flexibly adjust SiO₂, Al₂O₃, and MgO contents to suit the customer's operating conditions, ensuring long-term, stable service in high-temperature environments. As a national high-tech enterprise, Rongsheng holds multiple international certifications, including ISO9001, ISO14001, and CE. We rigorously implement a comprehensive quality control system, ensuring that each batch of products passes rigorous inspection before leaving the factory. We specialize in providing customized refractory system solutions for global steelmakers, helping them extend furnace lining life, reduce maintenance costs, and ensure production continuity. With over a decade of experience and a global service network spanning over 30 countries, Rongsheng continues to create value for its customers.
