High Quality 65% Ferrosilicon for Industrial Use

65% silicon iron (Si 63-68%) relies on a high-power ore blast furnace with a capacity of ≥ 25MVA to achieve continuous production. Its core lies in a fully automatic closed-loop ramming system: by monitoring the resistance changes of the furnace material in real time, dynamically adjusting the electrode insertion depth, ensuring the uniformity of the reduction reaction (temperature fluctuation in the furnace ≤ 15 ℃), and stably producing 200 tons per day. This product plays a dual role in the metallurgical field - it is not only the core reducing agent (MgO+FeSi → Mg+Fe+SiO ₂, magnesium recovery rate ≥ 92%) for the Pidgeon process of magnesium smelting, but also the matrix material for silicon aluminum alloy masterbatch. The deep processing stage adopts a three-level vacuum melting process (10 ⁻ Pa level high vacuum) to purify semiconductor grade polycrystalline silicon ingots with silicon content>99.5%, which are used for direct pull single crystal silicon growth.
