**Energy Group KeHuan Group achieves industrial transformation of coal-based new material technologies and their overseas application

Thread Content

On January 27, railway ore cars equipped with key wear-resistant and anti-corrosion materials supplied by **Energy Group KeHuan Group New Materials Company were manufactured at CRRC Taiyuan Company and shipped to Africa. This application marks COHENG Group’s achievement in the industrial transformation and overseas deployment of coal-based new material technologies, with its use for the first time in overseas rail transit equipment projects. Facing the challenging conditions in Africa, such as high temperatures, dust, and severe abrasion, traditional metal protection solutions are prone to issues like corrosion, wear, and material adhesion, which directly affect the service life and operational efficiency of vehicles. To this end, KeHuan Group’s New Materials Company has strengthened cooperation with CRRC Taiyuan Company as part of the efforts among central state-owned enterprises; by leveraging the coal-based new materials technology developed by the group’s Research Institute (Low-Carbon Institute), they have jointly developed a vehicle interior wall protection solution centered on functional composite panels. The material combination features properties such as corrosion resistance, impact resistance, and self-lubrication, which helps to significantly reduce material sticking and enables it to function in harsh environments with high humidity and high abrasion. Practical applications have shown that by adopting this protection scheme, the service life of the vehicle body can be extended by about 20%, while operating and maintenance costs can be reduced by 10%–15%, effectively addressing long-standing problems in this industry. This collaboration not only provides high-performance, reliable equipment protection solutions for railway transportation in Africa, but also enables KeHuan Group to make breakthroughs in the overseas market for coal-based new materials used in rail transit, thus creating a successful example of synergistic innovation and complementary strengths between new material research and development and high-end equipment manufacturing. In the future, KeHuan Group’s New Materials Company will continue to pursue material substitution strategies such as using plastics in place of steel, and deepen its cooperation with leading enterprises in the industry, thereby leveraging technological innovation to drive the high-quality development of China’s high-end equipment and new materials industries.
