Zhengzhou Rongsheng Kiln Refractory Co., Ltd. has been deeply engaged in the research and development and production of refractory materials for over 20 years. Its high-alumina refractory bricks are designed specifically for the high-temperature conditions of steelmaking furnaces. With an alumina content of up to 85%, they offer excellent high-temperature resistance (withstanding temperatures exceeding 1,600°C for extended periods), strong thermal shock resistance, and superior corrosion resistance. These products are ISO9001, ISO14001, and CE certified, and are manufactured using a fully automated intelligent production line to ensure consistent and reliable quality in every batch. They are widely used in linings for key high-temperature equipment such as steelmaking, electric furnace steelmaking, and continuous casting tundishes, helping customers extend kiln life, reduce maintenance costs, and ensure safe production. As a national high-tech enterprise, Rongsheng serves over 2,000 customers worldwide, offering a one-stop service ranging from selection consultation and customized solutions to on-site construction guidance. Rongsheng is a trusted supplier of export-grade high-temperature industrial materials.
1. An aluminum content of 85% significantly improves high-temperature strength and chemical stability. 2. Excellent thermal shock resistance allows for rapid temperature fluctuations. 3. Compliance with international certification standards (ISO/CE) ensures compliance with overseas project requirements. 4. A fully automated production line ensures batch consistency and reduces on-site construction risks. 5. Full-process technical service support ensures rapid response to customer needs.
It is suitable for lining high-temperature equipment such as steelmaking furnaces, electric arc furnaces, continuous casting tundishes, heating furnaces, etc. in the steel and metallurgical industry; it is suitable for large domestic and foreign steel mills, metallurgical engineering contractors, refractory material distributors and export trade projects; it is especially favored by customers in the Middle East, Southeast Asia, Europe and other regions who have strict requirements for high-quality refractory materials.
