Price Trends
- As of November 13, 2025, the price of silicon steel sheets was 4,250 RMB/ton, with minimal recent fluctuations.
- Xuzhou Jinhong Steel's scrap steel procurement prices (e.g., 3,470–3,520 RMB/ton as of July 30, 2025) indicate stability in silicon steel sheet pricing, unlike other material adjustments.
Technological Applications
- 0.20mm Ultra-Thin Grain-Oriented Silicon Steel Sheets: Used in China’s first 110kV "Super 1" energy efficiency transformer, reducing no-load loss by 28% and load loss by 12%, with energy consumption dropping to 0.60 W/kg.
- Pumped-Storage Power Plants: Projects like Nanning Pumped-Storage Station (140,000 sheets of 0.35mm) and Meizhou Pumped-Storage Station (104,000 sheets of 0.5mm) employ silicon steel sheets for stator core assembly, with precision controlled within 50 microns.
Industry Progress
- Flywheel Energy Storage Systems: Utilize 0.5mm silicon steel sheets as rotor magnetic lamination material, optimizing motor cooling.
- Yebatan Hydropower Station: The 5th generator’s stator core (90,000 sheets of 0.5mm, total weight 410 tons) highlights large-scale application in renewable energy.
