Zhengzhou Rongsheng Refractory Materials Co., Ltd. specializes in producing high-alumina bricks that meet ISO9001 international quality management system certification. With an Al₂O₃ content ≥85%, these bricks can withstand long-term stable operation at extreme high temperatures of 1750–1800°C. They possess excellent structural strength and strong corrosion resistance, making them particularly suitable for high-temperature kiln linings in industries such as steel, glass, and cement. The products have low thermal conductivity and excellent insulation performance, effectively reducing energy consumption and helping customers achieve green and low-carbon operations. With over 20 years of technical accumulation and a rigorous quality control system, Rongsheng ensures a 99% pass rate for each batch of products. Supporting customized design and full life-cycle services, Rongsheng is a trusted refractory material supplier for overseas customers.
