High Purity Furnace Pure Iron Ingots – Xinye Taiming
Ultra-Clean Feedstock for Precision Metallurgy
Product Overview
Xinye Taiming produces furnace-grade pure iron ingots with purity levels exceeding 99.99%, specifically engineered for foundries, specialty steelmakers, and high-temperature applications. Our ingots serve as the ultimate base material for alloys requiring ultra-low residuals, ensuring consistency in critical processes like vacuum induction melting (VIM) and electro-slag remelting (ESR).

Physical Properties:
Form: Standard 10–50kg ingots, or custom-cut blocks.
Density: 7.87 g/cm³ (non-porous, X-ray inspected).
Surface: Sandblasted finish to prevent oxidation during storage.
Melting Point: 1538°C (consistent ±2°C variation).
Manufacturing Process
Raw Material Selection:
Premium iron ore with <10ppm heavy metals (Pb, As, Sb).
Pre-screened scrap iron (optional for recycled-content grades).
Vacuum Arc Remelting (VAR):
Triple melting under 10⁻³ mbar vacuum to eliminate gaseous impurities.
Electromagnetic stirring ensures homogeneous composition.
Electro-Chemical Purification:
Molten iron treated with reactive slags (CaO-Al₂O₃-SiO₂) to absorb trace sulfur/phosphorus.
Ingot Casting:
Continuous casting with argon shielding to prevent surface contamination.
Controlled cooling rate (<5°C/min) to minimize internal stress.
Quality Control:
Glow discharge mass spectrometry (GDMS) for ppm-level impurity verification.
Compliance with ASTM A848, DIN 1743, and JIS G 2312 standards.
Key Applications
Specialty Steelmaking: Ultra-low carbon steels, silicon electrical steels.
Superalloys: Nickel/iron-based aerospace alloys (e.g., Inconel precursors).
Magnetic Materials: High-permeability cores, amorphous ribbon production.
Research & Standards: Certified reference materials (CRM) for calibration.
Additive Manufacturing: Spherical powder feedstock for laser bed fusion.
Competitive Advantages
Purity Guarantee: Batch-specific GDMS reports with traceability codes.
Flexible Formats:
Ingot sizes: 10kg, 25kg, 50kg (±0.5% weight tolerance).
Custom shapes: Rectangular, cylindrical, or trapezoidal.
Rapid Delivery: Stocked grades ship within 72 hours; custom orders in 10–15 days.
Sustainability: Option for 30–100% recycled-content ingots (with full impurity disclosure).
Certifications: IATF 16949, ISO 17025, and RoHS/REACH compliant.
FAQ
Q1: What is the hydrogen content in your ingots?
A: Hydrogen is controlled to ≤0.5ppm through vacuum degassing, ideal for hydrogen-sensitive applications.
Q2: Can ingots be machined into crucible charges?
A: Yes, we offer precision-turned chunks or pre-weighed charges for VIM/ESR furnaces.
Q3: Do you supply ingots for nuclear applications?
A: Yes, neutron-grade ingots (Co ≤0.1ppm, B ≤0.05ppm) available upon request.
Q4: How are ingots packaged to prevent rust?
A: Individually wrapped in VCI film, palletized with desiccant, and crated for ocean freight.
Q5: What is the maximum ingot size?
A: Standard production up to 500kg. Larger monoblocks (1–5 tons) require advance notice.
Package
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.
