Since 2017, Baosteel has been actively adapting itself to the situation of concentrated start-up of the UHV transmission line projects in the power industry and higher requirements for the supply nodes of the transformer manufacturers. The Company continued to optimize the break-protection management model with the characteristics of silicon steel and implemented the linkage of production, grade oriented silicon steel to expand the market. It achieved remarkable results. The top grade oriented silicon steel, represented by B27R085 and B23R080, successfully replaced the imports, meeting the needs of downstream users represented by the three major transformer manufacturers. It lay a solid foundation for promoting the localization of major equipment, and oriented silicon steel to enhance their profitability.
