Low content Si 15 ferrosilicon high quality

FeSi55 derives its critical low-carbon (<0.1%) and controlled-silicon (52-55%) specifications from precisely managed 1400-1500°C smelting in coke-fired furnaces, where silica reduction kinetics are optimized for cost-efficient impurity separation. This unique metallurgical profile enables dual industrial functions: instantaneous deoxidation during steelmaking – generating fluid CaO-SiO₂-Al₂O₃ slags that absorb non-metallic inclusions – and measurable improvement in cast iron fluidity for complex gray iron molds. Production leverages scalable electric arc or blast furnace technology with strict slag basicity control. The alloy is supplied in 1-ton hygroscopic bulk bags (internal PE barrier) or nitrogen-flushed steel drums, all marked with ISO-compliant safety pictograms. Secondary processing includes jaw crushing for 10-50mm ladle-ready fractions or jet-milling for ≤3mm injection-grade powders used in coreless induction furnaces. Transport mandates adherence to IMDG Code 4.1 (UN 1408…
