Recently, the National Intellectual Property Administration disclosed an invention patent application by Ningbo Zhongding New Material Technology Co., Ltd. - "An Automated Production Line and Production Method for Stainless Steel Strips" (Publication No.: CN120094977A). This patent focuses on solving key process challenges in the production of cold-rolled precision stainless steel strips. Through integrated production line design and intelligent control strategies, it effectively addresses the issue of strip surface "wrinkling", significantly enhancing product flatness and dimensional accuracy.

      Established in 2020 and located in Fenghua District, Ningbo, Zhejiang, Ningbo Zhongding New Material Technology Co., Ltd. is a technology enterprise specializing in the research, development, and manufacturing of high-quality cold-rolled precision stainless steel strips and other alloy strips. The company's products have a width of ≤600mm, with thickness ranging from 0.05mm to 2.0mm, including various types of surface treatments such as 2B, 1D, DF matte, among others. They can provide strips in soft, semi-hard, hard states, etc., widely used in automobile manufacturing, new energy, electronic components, and other fields.

      In practical production, cold-rolled stainless steel strips often exhibit microscopic "wrinkles" or wavy edge defects due to uneven tension, unreasonable roller configuration, or fluctuations in annealing processes, severely impacting subsequent processing procedures like stamping, laser cutting, or welding. Especially in high-precision application scenarios, such as HEV hybrid transmission torque buffer plates, EGR exhaust gas recirculation system components, etc., the requirements for material surface quality are extremely stringent.

      To address this common industry issue, the R&D team at Zhongding New Materials has developed an automated production line solution that integrates multi-level cleaning, high-precision rolling, controlled atmosphere annealing, and intelligent rewinding. By real-time monitoring of strip running tension and plate shape changes, this system dynamically adjusts parameters across each process stage, ensuring stability throughout the entire process from uncoiling to rewinding. Additionally, optimizing the annealing furnace temperature control curve avoids local deformation caused by thermal stress, achieving a highly consistent surface smoothness and flatness of the strips.

      This technological breakthrough not only improves product yield but also provides a more reliable material foundation for downstream customers in complex forming processes. For instance, in the stamping process of automotive exhaust heat shields, high-flatness stainless steel strips can reduce mold wear and improve part consistency; in the preparation of high-temperature superconducting substrates, reduced surface defects help enhance the adhesion and electrical performance stability of the superconducting layer.

      As a company adhering to the philosophy of "Wisdom Refinement, Innovation Leading Far", Zhongding New Materials continuously deepens industry-academia-research cooperation, jointly innovating material processes with universities and research institutions. The disclosure of this patent represents an important demonstration of the company's technical accumulation in the field of precision alloy strip manufacturing. In the future, the company will continue to focus on strategic directions such as new energy vehicles and clean energy equipment, optimizing product structures, strengthening process control capabilities, and providing higher-value material solutions for advanced manufacturing industries.

      Ningbo Zhongding New Material Technology Co., Ltd., established in 2020 and situated in Fenghua District, Ningbo, covers an area of 5000 square meters. The company specializes in the development and application of high-quality cold-rolled precision stainless steel strips and other alloy strips.
