The development of oriented silicon steel is advancing toward higher magnetic induction, lower iron loss, and thinner specifications, driven by growing demand from the new energy sector and high-end equipment manufacturing. Below is a detailed analysis of the key trends:
1. Technological Upgrades
- High Magnetic Induction & Low Iron Loss: Leading manufacturers like Baosteel have achieved mass production of ultra-thin 0.1mm silicon steel, significantly reducing iron loss and improving motor efficiency.
- Thinner Gauges & Higher Grades: Advanced rolling and casting technologies (e.g., twin-roll strip casting) enable the production of thinner, higher-grade silicon steel, such as Baosteel’s 3.1% silicon-content products.
2. Expanding Applications
- New Energy Sector:
- Electric vehicles (EVs): High-grade non-oriented silicon steel is critical for EV drive motors.
- Renewable energy (wind/solar): High-magnetic induction oriented silicon steel is essential for transformers in wind and solar power systems. The new energy transformer market is projected to exceed ¥120 billion by 2025 and reach a trillion-yuan scale by 2035.
- Emerging Technologies: Fields like humanoid robots and low-altitude aviation are driving demand for lightweight, high-precision silicon steel.
3. Market & Export Trends
- Capacity Growth: China’s oriented silicon steel capacity reached 3 million tons in 2024, with production at 2.95 million tons, and is expected to grow to 3.35 million tons by 2025.
- Export Surge: In 2024, net exports hit 566,000 tons, with an average export price of 1,910/ton**‌—‌**918/ton higher than imports, primarily flowing to Europe, the U.S., and Japan.
4. Industrial Chain Integration
- Regional Clusters: Industrial hubs like Loudi, Hunan, have formed complete supply chains from raw materials to motor components, enhancing cost efficiency.
- Vertical Integration: Companies like Chongqing Wangbian Electric are expanding upstream, creating a full product chain from silicon steel to transformers and equipment.
Conclusion
The future of oriented silicon steel lies in technological innovation (thinner, higher-grade materials) and application expansion (new energy, high-end equipment). China’s growing production capacity and strong export competitiveness position it as a key player in the global market.
