BaoSteel announced that its Plate Division has successfully completed the delivery of the magnetic shielding 5m thick steel plate used in the third-generation nuclear power’s steam turbine generator of the Guohe No 1, supporting China’s leap from a nuclear power country to a nuclear power, fully demonstrating the mission of central enterprises. BaoSteel started the independent research and development of magnetic shielding steel plates in 2012 and after ten years of close cooperated closely with users has conducted trial production, first-site certification & second-party evaluation etc and finally supplied the material for the first time in 2021, substituting importsIn the process of independent research and development for many years, Baosteel's magnetic shielding steel plate research and development team has continuously optimized and improved various electromagnetic properties in terms of product composition and process design, and has fully considered the impact of each process step on organizational structure and process design. The influence of electromagnetic performance overcomes the difficulties of limited detection means and lack of detection standards. During the period, Baosteel's magnetic shielding steel plate R&D team received strong support from the silicon steel team, and established electromagnetic performance testing methods and evaluation standards from scratch, which were fully recognized by users.Guohe No 1 is indigenously designed Chinese nuclear power technology brand, representing the world's advanced level of third-generation nuclear power. The third-generation nuclear power technology has high safety, good economy, strong constructability, and convenient operation and maintenance.
