Even though the craft of forging goes back thousands of years in human history, technical innovation is still a great motivation within this old industry. From the connection flange on the 8MW giant offshore wind turbine to the innovative supporting ring in the fourth-generation nuclear power utility, we are inheritors of such technology. As a result, we are committed to facing severe engineering challenges with our global customers, and work on more refined technical improvements and cutting-edge technological innovation to forge a safe, green and intelligent industry in the future.
We are deeply aware of the importance of scientific research and practical experience in the forging industry. Based on this, we have collaborated with the School of Materials Science and Engineering at Shandong University and the Shandong Jianzhu University for many years. In 2015, we co-founded the "Academician Li Yiyi Workstation" with the Institute of Metal Research, Chinese Academy of Sciences, and extended our cooperation in fields of large forging technology, development of new steel grades and material preparation. The team led by academician Li Yiyi has made great contributions in the research of low-temperature and high-voltage, anti-hydrogen embrittlement super-alloy development, turbine blades of the Three Gorges Dam and nuclear power large pressure vessels. Academician Li Yiyi was conferred with Lifetime Achievement Award of Metallurgical Technology by Chinese Society for Metals.
