Silicon Alloy Smelting Plant

Our silicon metal plant design is optimized according to your needs. Metso's Outotec Söderberg electrode equipment is proven technology for ferrosilicon production and high availability and low specific energy consumption is guaranteed by high quality materials and an easy-to-maintain design.

For silicon metal production, Metso offers a graphite electrode system. Operating cost levels can be decreased with composite electrodes, which combine the benefits of graphite electrodes and Söderberg electrodes. The overall energy efficiency can be improved with a heat recovery system to produce hot water, steam, or electricity. Our rotating furnace design promotes the longer life time of the refractory lining and makes operation easier. Silica fume is recovered from the off-gas and packed ready for shipping.

  • Furnace sizes range from 20 to 45 MW
  • Integration with other Metso heat recovery systems is possible
