4. Manufacturing Process
Our vertically integrated production ensures unmatched quality:
Step 1: Vacuum Induction Melting (VIM)
- Melts raw iron under 10⁻³ Pa vacuum to remove O₂, N₂, and H₂.
- Achieves initial purity of 99.93%.
Step 2: Electro-Slag Remelting (ESR)
- Eliminates sulfur and non-metallic inclusions (e.g., Al₂O₃).
- Final purity: 99.95%.
Step 3: Precision Forming
-Cold Rolling: Produces sheets/strips with ±0.01mm tolerance.
-Annealing: Hydrogen atmosphere annealing at 1,100°C for stress relief.
Step 4: Quality Assurance
- 3D X-Ray Testing: Detects micro-voids and inclusions.
- Magnetic Flux Testing: Validates permeability (µ) and coercivity (Hc).
