Technical Advantages
High Recovery: Sealed core prevents oxidation, keeping chemistry variance within ±0.05%.
Jam-Free Sheath: Strong mechanical seam lock allows smooth feeding up to 3.5 m/sec with zero powder leakage.
15% Less Slag: Controlled dissolution reduces oxide inclusions and temperature spikes.
Direct Replacement Ratio: 1.0 kg SiC wire replaces 1.2 kg FeSi75 and 0.3 kg recarburizer.
OEM & Customization
Chemical Grade Customization: Tailored SiC purity levels (70%–98%) and particle size distributions (0–1 mm / 0–3 mm).
Dimensional Specifications: Custom wire outer diameter (9–16 mm) and steel strip thickness to match specific melt depths.
Packaging Configurations: Custom coil inner/outer diameters, customized labeling, and moisture-proof export packaging.
Packaging & Logistics Logistics
Moisture Defense: Inner sealed plastic lining with outer heavy-gauge shrink wrap to eliminate air exposure and corrosion during ocean transport.
Structural Support: Vertical or horizontal eye-to-sky steel frame packaging secured on heat-treated ISPM-15 wooden pallets.
Container Loading: Compact stacking engineered for max payload utilization in 20ft and 40ft containers.
Manufacturing & Quality Assurance
Raw Material Verification: Every batch of raw SiC powder undergoes X-ray Fluorescence (XRF) and Carbon-Sulfur analyzer testing to verify purity prior to processing.
Online Process Control: Automated continuous filling machinery monitors linear density in real-time, ensuring <2% core density fluctuation along the entire coil length.
Finished Product Inspection: Each production lot undergoes sheath thickness measurement, strip tensile strength testing, seam tightness checks, and chemical verification.
Full Traceability & Inspection Reports: Ships with complete lot-number tracking and factory chemical test reports for every batch.

FAQ
Q: What is the main operational advantage of SiC Cored Wire over lump SiC or Ferrosilicon?
A: Deep-injection via steel sheath protects the SiC core from atmospheric oxidation at the bath surface. This ensures uniform dissolution, higher element recovery (up to 85%+), and eliminates dust pollution in the foundry.
Q: How do you prevent wire breakage or jamming during high-speed feeding?
A: We utilize cold-rolled steel strips with controlled tensile strength and seam locking technology. The wire maintains flexibility without splitting or kinking when passed through guide tubes and wire feeders at speeds up to 3 m/sec.
Q: What is the typical shelf life and storage requirement for this product?
A: When stored in its original sealed, moisture-proof packaging in a dry, covered warehouse, the product has a shelf life of at least 12 months without sheath rusting or core moisture absorption.
Q: How is core filling density monitored during manufacturing?
A: Our automated production lines employ inline load-cell sensors and continuous weight-per-meter checking to ensure a stable filling ratio above 85%, avoiding hollow segments that cause inconsistent melt chemistry.
Q: Can you match existing cored wire feeder dimensions in our plant?
A: Yes. We customize coil inner diameter (ID), outer diameter (OD), coil height, and payoff direction (internal or external extraction) to fit your existing feeding system layout.
Q: What chemical test reports and quality documents are included with shipments?
A: Every shipment includes an EN 10204 3.1 Mill Test Certificate (MTC) detailing exact chemical composition (SiC, C, Si, Fe, S, P), wire diameter tolerances, linear mass, and lot numbers. Third-party inspection reports (e.g., SGS, BV) are available upon request.
Q: What is the typical lead time for custom specification orders?
A: Standard specifications ship within 7–10 days. Customized chemical formulations, specific wire diameters, or specialized coil dimensions typically take 14–20 days from order confirmation.
