Core Performance Features
Active Silicon Deoxidation: High silicon content (65% Min) rapidly binds dissolved oxygen to form SiO2 slag, lowering oxygen levels below 20 ppm and eliminating steel porosity.
Submerged-Arc Purity: Smelted using high-purity silica (SiO2 > 99.2%) in closed electric furnaces, keeping S <= 0.02% and P <= 0.04% to prevent metal embrittlement.
Air-Cleaned Mechanical Screening: Double-sieved with air dusting to keep fine powder (< 2 mm) below 5%, ensuring high sink-in melt rates and zero furnace dust loss.
Primary Applications
Steelmaking: Secondary metallurgy deoxidation and alloying for carbon and stainless steels.
Foundry Operations: Inoculation agent for grey iron and ductile iron production to prevent chill formation.
Magnesium Metallurgy: Reducing agent in the Pidgeon process for magnesium production.
OEM & Customization Options
Sizing: Custom sizing down to specific mesh sizes (e.g., 0.2–1 mm for inoculation).
Chemical Tailoring: Ultra-low Aluminum (Al < 0.5%) or low-Carbon grades available upon request.
Private Labeling: Custom bag markings, color coding, and shipping marks.
Packaging & Shipping
Bulk Bags: 1,000 kg or 1,250 kg UV-resistant jumbo bags with top discharge spout.
Small Bags: 25 kg multi-wall paper or PE bags packed onto fumigated wooden pallets.
Protection: Waterproof inner liner applied to all packaging options to prevent humidity oxidation during sea freight.
Logistics: FCL container loading and bulk vessel shipments with monthly capacity exceeding 5,000 MT.
Quality Assurance & Compliance
Raw Material Control: High-purity quartz and coke inspected before submerged arc furnace melting.
In-House Testing: XRF spectrometer analysis conducted for every molten heat.
Third-Party Inspection: SGS, BV, or Intertek sampling and COA (Certificate of Analysis) available for every shipment.

FAQ
Q: What is the typical lead time for a 20ft container order?
A: Standard orders (10–50 mm lump form) are dispatched within 7–10 days after order confirmation. Custom sizing or specialized chemical grades require 14–18 days.
Q: Can you supply low-Aluminum Ferro Silicon 65?
A: Yes. We offer low-Al grades (Al ≤ 0.5% or Al ≤ 1.0%) for specialized steelmaking and high-grade casting applications.
Q: How do you prevent breakage and secondary dust creation during transport?
A: We use reinforced pallets and high-tension shrink wrap to lock bags in place and absorb transit vibration, preventing particle friction and secondary damage.
Q: How is a third-party inspection (SGS/BV/Intertek) arranged and paid for?
A: Requests must be made 5 business days before loading. Inspections can take place at our factory or port, with costs handled per contract terms or by the buyer.
Q: Can I request free samples for foundry trials?
A: We provide free 1–3 kg samples for laboratory or small-scale trial testing. Express freight costs are covered by the buyer or offset against future bulk orders.
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 20 Metric Tons (one 20ft container). Trial orders of 1–5 MT can be arranged upon request.
Q: How effective is your ocean freight packaging against moisture and damage?
A: Sealed PE inner liners and pallet shrink-wrap protect against sea humidity and keep cargo damage rates below 0.5% for both FCL and LCL shipments.
