On September 13, 2020, Professor Xin Shaojie from the School of Mechanical Engineering visited Northeastern University and hosted an expert consultation meeting on the project of "Development of Ultra-clean 7000PPM High Nitrogen Steel Retaining Ring". Chief Engineer Liu Xihai and Professor Liu Tao of the School of Metallurgy of Northeastern University, and Tang Shidou, General Manager of Forging Branch of Shenyang Casting and Forging Industry Co., Ltd. attended the project consultation meeting.

Professor Xin first introduced the background of the subject and the follow-up work arrangements, and thanked the participating experts for attending the consultation meeting. Chief Engineer Liu Xihai introduced the technical status and standards of steel used in domestic and outer retaining rings, and introduced the materials and manufacturing processes of ultra-clean retaining ring steel from Northeastern University to the German standards, focusing on the proprietary technology of high nitrogen retaining ring steel manufacturing: High-nitrogen control technology, ultra-pure control technology, development of special slag system, production equipment innovation, electroslag process innovation, etc. Participating experts conducted enthusiastic discussions around the theme and formed a number of consensus. Everyone said that in the future, they will jointly tackle key problems, solve the problem of retaining ring materials and manufacturing technology, and change the current situation of large-scale retaining rings relying on foreign imports.
