I. Why Electromagnetic Equipment Cannot Function Without Silicon Steel Sheets

When electric current interacts with magnetic fields, ordinary steel generates excessive heat and suffers performance degradation due to severe eddy current loss. Silicon steel sheets act as a “heat-insulating barrier” in electromagnetic systems and resolve this issue via the following mechanisms:

• Silicon alloying effect: A silicon content of 3% multiplies electrical resistivity fivefold and effectively suppresses eddy currents.
• Oriented grain arrangement: The cold rolling process creates an unobstructed magnetic flux path and reduces hysteresis loss.
• Precise thickness control: Thin sheets ranging from 0.23 mm to 0.35 mm further cut energy waste.

II. How Performance Advantages Translate into Practical Value

Inside transformer cores, high-quality ဆီလီကွန်သံမဏိ sheets push equipment efficiency above 97%:

• Outstanding energy-saving performance: Cuts no-load loss by 60% compared with regular steel.
• Low noise operation: Magnetostriction coefficient as low as 0.5×10⁻⁶, resulting in quiet operation.
• Reliable mechanical strength: Tensile strength up to 400 MPa without cracking during stamping.

III. Overlooked Hidden Properties During Procurement

These indicators directly determine service life:

• Coating category: Inorganic coatings withstand temperatures up to 800 °C, while organic coatings only tolerate 200 °C.
• Aging performance: Core loss may rise by 3%–5% after six months of storage.
• Stacking factor: A minimum stacking factor of 95% is required for smooth magnetic flux transmission.
