Low content Si 15 ferrosilicon high quality

The key low-carbon (<0.1%) and thyristor (52-55%) specifications of FeSi55 come from precise management of 1400-1500 ° C smelting in coke combustion furnaces, where the kinetics of silica reduction are optimized to achieve cost-effective impurity separation. This unique metallurgical characteristic achieves dual industrial functions: instantaneous deoxidation during steelmaking - producing CaO SiO fluid ₂ - Al ₂ O3 to absorb non-metallic inclusions in slag, and measurable improvement in the flowability of complex gray cast iron molds. Production and utilization of scalable arc or blast furnace technology, strict control of slag alkalinity. The alloy is supplied in the form of a 1-ton hygroscopic bulk bag (internal PE barrier) or nitrogen flushed steel drum, and all packaging is labeled with safety pictograms that comply with ISO standards. Secondary processing includes jaw crushing of 10-50mm ladle preparation grades or jet grinding of ≤ 3mm injection grade powder used in coreless i…
