High Purity Ferro Silicon 75 Production
In the production of electrical steel, stainless steel and high-grade ductile iron, standard-grade FeSi 65 often fails to meet strict quality requirements. High Purity Ferro Silicon 65 is specially formulated for applications where trace elements - especially aluminum (Al), calcium (Ca) and carbon (C) - must be tightly controlled to avoid slag inclusions and hydrogen porosity.
At ZhenAn, we produce our FeSi 65 in submerged arc furnaces using high-grade silica and low-ash reducing agents, delivering a product with excellent solubility and consistent chemical stability.
Technical Specifications of Ferro silicon 65
| Chemical Element | High Purity Grade (HP) | Low Al Grade | Standard Grade |
| Silicon (Si) | 63.0 - 68.0% | 63.0 - 68.0% | 60.0 - 70.0% |
| Aluminum (Al) | ≤ 0.10% / 0.5% | ≤ 1.0% | ≤ 2.0% |
| Calcium (Ca) | ≤ 0.10% | ≤ 0.5% | ≤ 1.5% |
| Carbon (C) | ≤ 0.02% | ≤ 0.04% | ≤ 0.1% |
| Phosphorus (P) | ≤ 0.03% | ≤ 0.035% | ≤ 0.04% |
| Sulphur (S) | ≤ 0.01% | ≤ 0.015% | ≤ 0.02% |
- Custom Sizing: Available in 10-50mm (Ladle addition), 50-100mm (Furnace charging), or specialized 1-3mm grains for inoculants.
- Slag Control: The ultra-low Al and Ca content significantly reduces the formation of Al₂O₃ inclusions, improving the cleanliness of the steel.
High Purity Ferro Silicon 65 Key Features
- Chemical Precision: Ultra-low impurities (Al ≤ 0.1%, C ≤ 0.02%) ensure steel cleanliness and optimal magnetic properties.
- High Recovery: Dense crystal structure ensures rapid melting with a Si recovery rate ≥ 95%, reducing smelting costs.
- Physical Quality: Double-mechanical screening limits fines (<10mm) to under 10%, preventing furnace blow-outs.
- Supply Resilience: 100,000 MT annual output with 5,000 MT buffer stock at Tianjin Port for 7–14 day delivery.
- Verified Trust: Full batch traceability with SGS/BV third-party inspection as a standard export protocol.
