Innovative Pure Iron Manufacturing Process
We combine vacuum induction melting (VIM) and electro-slag remelting (ESR) to achieve ultra-low impurity levels. Our proprietary 6-stage refining system ensures precise chemistry control.
Key Production Stages
| Stage | Technology | Impurity Reduction | Unique Feature |
|---|---|---|---|
| Raw Material Selection | XRF Spectroscopy | Eliminates surface oxides | AI-driven scrap sorting |
| Primary Melting | VIM Furnace | Reduces C, S by 90% | Hydrogen-free environment |
| Secondary Refining | ESR System | Lowers O₂, N₂ to <10ppm | Directional solidification |
| Final Forming | Hot/Cold Rolling | Maintains 99.9% density | Customizable thickness (1-50mm) |
All processes comply with ASTM A848 and DIN 17100 standards.
Pure Iron Applications by Industry
Different purity grades serve specialized roles across sectors. Below are verified use cases:
| Industry | Grade Used | Component Example | Performance Benefit |
|---|---|---|---|
| Medical Devices | Fe-99.99 | MRI shielding plates | Zero magnetic interference |
| Renewable Energy | Fe-99.95 | Fuel cell bipolar plates | 35% higher corrosion resistance |
| Precision Machinery | Fe-99.9 | Hydraulic valve cores | 99.8% dimensional stability |
How Our Process Enhances Quality
Trace Gas Control – ESR reduces oxygen to <5ppm vs. industry average 15ppm.
Grain Structure – Uniform 8-12μm grain size improves machinability by 20%.
Sustainability – Closed-loop argon recycling cuts emissions by 40%.
Case Example: A Japanese robotics company reduced part rejection rates from 8% to 0.5% using our Fe-99.95 grade for actuator components.
Technical Advantages Over Competitors
| Parameter | Our Pure Iron | Industry Standard | Improvement |
|---|---|---|---|
| Surface Roughness | Ra ≤0.8μm | Ra ≤1.5μm | 47% smoother |
| Residual Stress | <50 MPa | 80-120 MPa | 60% lower |
| Batch Consistency | ±0.003% chemistry | ±0.01% chemistry | 3x tighter |
FAQs: Pure Iron Production
Q: Why use VIM+ESR instead of traditional methods?
A: The dual-process removes tramp elements (e.g., Pb, Sn) undetectable in conventional arc furnaces.
Q: Can you produce magnetic shielding alloys?
A: Yes – We adjust silicon content (0.5-4%) while maintaining >99.8% Fe purity for customized permeability.
Package
F-1 Pure Iron is typically packaged with rust-preventive oil, wrapped in plastic film, and secured with plastic or metal straps. It is then placed on wooden pallets or in wooden crates, sometimes using moisture-proof paper or vacuum packaging for extra protection during transportation and storage.
