On January 23, Linqing City held a symposium on the topic of "Ultrasonic Testing Regulation and Deformation Control Methods for Bearing Residual Stress". Director Qin Zhihui and Professor Xu Chunguang from Beijing Institute of Technology were invited to provide guidance. Li Guang, Secretary of the Party Leadership Group and Director of the Municipal Industry and Information Technology Bureau, Wang Qingrui, Honorary Secretary-General of the Municipal Bearing Association, Song Ziliang, Advisor, and the heads of more than 20 key enterprises including Huagong Bearing participated in the discussion.

The conference focused on key common technical challenges in the industry, engaging in in-depth discussions around cutting-edge topics such as "ultrasonic detection method for residual stress of bearing inner and outer rings/rolling elements", "high-energy sound beam regulation technology", and "stress gradient pre-setting process". The expert team systematically introduced the latest theoretical achievements and engineering paths for residual stress detection and regulation, providing important technical support for enterprises to enhance bearing reliability, precision retention, and fatigue life.

After the meeting, the expert team visited the production line of Shandong Huagong Bearing Co., Ltd. to conduct on-site investigations into key processes such as processing, testing, and assembly. Based on the actual production conditions of the enterprise, they conducted on-site diagnosis and technical guidance for specific issues such as residual stress control and deformation prevention. They also gave positive feedback on Huagong Bearing's exploration in process optimization.

This in-depth industry-university-research cooperation not only brings leading stress control solutions to Linqing's bearing enterprises in China, but also builds a bridge between the scientific research advantages of universities and the actual needs of the industry. With the wisdom and empowerment of top experts, Linqing's bearing industry is expected to take a solid step in improving product consistency and breaking through the high-end market, injecting new momentum into the high-quality development of regional manufacturing.
