Low-content ferrosilicon Si 15 cast ferrosilicon

  FeSi55 (55% silicon ferrosilicon) serves as the industry benchmark for efficient steelmaking deoxidation. Its rapid formation of low-melting-point silicate slag accelerates impurity removal, directly enhancing molten steel purity and reducing refining time. In foundries, it significantly lowers the viscosity of molten iron, preventing cold shuts in gray iron castings while minimizing slag pocket defects. Produced via coke-based reduction of iron ore/silica in blast or electric furnaces, its optimal cost-performance stems from strict 1400-1500°C thermal control – ensuring consistently low carbon residuals. Packaging includes 1-ton PE-film-lined woven bags or oxidation-proof steel drums, clearly labeled with batch traceability codes and hazard symbols. For specialized applications like submerged arc welding or torpedo ladle treatment, it can be precision-crushed to 10-50mm granules or micro-graded 0-3mm powder. Global shipments require IMDG Class 4.1-compliant, waterproof containers (2…
