High Quality 65% Ferrosilicon for Industrial Use

Silicon iron (with a silicon content of 63-68%, commonly known as 65 silicon iron) needs to be continuously smelted and produced in a large submerged arc furnace with a power of not less than 25MVA. Its core technology lies in the fully automatic closed-loop pounding furnace system: by monitoring the changes in furnace resistance in real time, dynamically adjusting the depth of electrode insertion, ensuring uniform and stable reduction reaction (temperature fluctuation in the furnace ≤ 15 ℃), and achieving a stable daily output of 200 tons.This product has dual core functions in the metallurgical field: it can serve as a key reducing agent for the Pidgeon process of refining magnesium (MgO+FeSi → Mg+Fe+SiO ₂, magnesium recovery rate ≥ 92%), and is also the basic raw material for silicon aluminum alloy master alloys. In the deep processing stage, a three-stage vacuum melting process (10 ⁻ Pa high vacuum environment) can be used to further purify and produce semiconductor grade polycryst…
