Applications of High-Silicon Silicon Steel
I. Invisible Protective Material for Power Transformers
High-silicon pepejal silikon (silicon content above 3%) is the optimal material for power transformer cores, which enables smooth transmission of magnetic flux just like ice skates gliding effortlessly on ice:
- 40% lower hysteresis loss: Orderly arranged silicon atoms form well-defined magnetic domains and drastically reduce heat generation.
- 60% reduced eddy current loss: Its electrical resistivity is 5 times higher than ordinary steel, effectively blocking circulating eddy currents.
- 15% cut in no-load power consumption: A 500 kV transformer can save 200,000 kWh of electricity annually.
II. Silent Performance Upgrade for Motor Cores
When the rotating speed of new energy vehicle motors exceeds 10,000 rpm, high-silicon pepejal silikon delivers outstanding performance:
- Improved magnetic saturation capacity: Operates stably under a magnetic flux density of 1.8 T without overheating.
- Optimized high-frequency loss: Loss at 10 kHz working condition is only one-third that of conventional pepejal silikon.
- Reduced vibration and noise: Its magnetostriction coefficient is 50% lower than traditional materials.
III. Future Material for High-Frequency Equipment
High-silicon silicon steel is expanding its application scope from 5G base stations to wireless charging devices:
- Electromagnetic shielding: Absorbs over 90% of radiation in the 1–100 MHz frequency band.
- Magnetic shielding housings: Shields precision instruments from stray magnetic field interference.
- Photovoltaic inverters: Core functional material that boosts conversion efficiency up to 99%.
