On March 27, 2025, the Shougang Oriented Soft Magnetic Materials User Technical Seminar was grandly held in Xi'an. Two new products, 23SQGD080DCR and 20SQGD070LN, were launched globally, alongside the release of several advanced technologies and new applications. The event attracted active participation from leaders of Shougang Shares and Shougang Zhixin, industry experts, shareholders, user representatives, and members of the production, sales, and research teams.
The two newly launched oriented soft magnetic material products are high-end achievements developed by Shougang with a focus on new-quality productivity. By deeply understanding industry trends, fully meeting customer-specific needs, and leveraging comprehensive technological innovation advantages, Shougang has successfully created these cutting-edge products.
New Quality Leadership: Global Launch Fills Industry Gaps The 23SQGD080DCR product addresses the DC bias issue in transformers under new application scenarios by mitigating the impact of DC bias at the material level, thereby enhancing transformer operational stability. This product increases excitation current by over 30%, significantly improving the transformer's tolerance to DC bias and effectively suppressing iron loss increases under DC bias conditions, reducing transformer heating. The 20SQGD070LN product innovates multiple technologies, breaking through the long-standing industry bottleneck between "low iron loss" and "low noise." While maintaining ultra-low iron loss performance, it reduces noise levels by 3 to 4 decibels, making it the quietest scalable soft magnetic material of its grade globally. It provides core material support for building efficient, energy-saving, and environmentally friendly new power grids.
Ultimate Service: New Application Technologies Drive Industry Development At the conference, Shougang unveiled its latest Early Vendor Involvement (EVI) technology for the first time. Collaborating with downstream users, Shougang Zhixin achieved full-chain technological innovation across materials, design, processing, and services, successfully breaking through three major technical bottlenecks in transformer core design, injecting new momentum into the industry's high-quality development.
To address additional losses caused by positioning holes in automatic stacking machines, Shougang collaborated with users, analyzing thousands of experimental data points to reveal the relationship between positioning holes and additional losses. This verified the compatibility of Shougang’s full series of 0.18-0.23mm silicon steel with intelligent production lines. Regarding core structural coefficients, Shougang pioneered a simulation model for core width-to-height ratios, developing a formula for calculating core structural coefficients and successfully solving the matching challenges of "tall and slim" cores. Facing the "high harmonic" challenge of new power systems, Shougang established a material database for harmonic operating conditions, providing crucial support for stable operation of renewable energy transformers under harmonic conditions. Its 0.18mm ultra-thin premium silicon steel achieved a 15% efficiency improvement in harmonic environments, contributing to the safety and efficiency of new power systems.
Green Start: Low-Carbon Products Support the "Dual Carbon" Strategy The conference also introduced green, low-carbon manufacturing technologies and related products. Through extreme energy efficiency management and breakthroughs in high scrap steel ratio and high pellet ratio technologies, Shougang Shares continuously increased carbon reduction during manufacturing. By promoting green electricity applications, Shougang further enhanced the green content of its soft magnetic materials. Currently, Shougang Zhixin has achieved mass supply of soft magnetic materials with a 40% carbon reduction, providing strong support for the low-carbon development of the steel industry and the implementation of the "Dual Carbon" strategy. At the end of the conference, Vice President Guo Zhenyan of the China Electrical Equipment Industry Association delivered a summary speech, and Yang Guo, General Manager of the Global Supply Chain at TBEA Co., Ltd., also shared insights. Experts presented reports on topics such as "Application and Development of New Oriented Silicon Steel for High-Efficiency Transformers in Low-Carbon Power Grids" and "Green Empowerment, Smart Manufacturing for the Future: Supporting Transformer Efficiency Upgrades." The management team of Shougang Zhixin provided detailed introductions of the performance characteristics and technical advantages of the two newly launched products, engaging in in-depth discussions on new products, technologies, applications, industry trends, and industrial chain collaboration.
Shougang’s oriented soft magnetic materials have passed certifications such as "UHV" (Ultra-High Voltage) and "Double Million" projects, achieving internationally leading comprehensive performance. These products are widely used in UHV transmission and distribution fields and key projects like the "Belt and Road Initiative," demonstrating Shougang's responsibility and commitment in advancing the "Dual Carbon" strategy. To address industry challenges and meet customer-specific needs, Shougang has innovatively developed multiple products tailored to industry requirements.
