The Ferro-Silicon Committee is a Trade Committee addressing Commercial Policy issues and making decisions in respect of Trade Defence.

Product and its uses

Ferro-Silicon is the most widely used deoxidising agent in the steel industry, although its consumption has strongly decreased in Western Europe over the last 25 years, from around 7.5 kg/tonne of steel, down to approximately 3.5 kg/tonne of steel today, thanks to improvements in metallurgical treatments and the standardisation of the continuous casting of steel. Ferro-silicon is available in different grades (see ISO 5445):

  • According to the Silicon content, 75%, 65% or 45% are the most popular, but in Western Europe high levels of Silicon are preferred;
  • According to impurity levels, mainly Aluminium, but also other metals are considered as non-desirable in specific applications.

Production processes

Ferro-Silicon is produced in electric submerged-arc furnaces, with Söderberg electrodes, from quartz and carbon bearing products (charcoal, coke, wood chips, etc.).

Details are available in the Non-Ferrous Metals BREF Note published by the EU Commission (http://eippcb.jrc.es).

The production of Ferro-Silicon is an energy-intensive activity and the modern and efficient large furnaces operated by EUROALLIAGES' Members allow them to reach high yields, thereby achieving the lowest possible levels of energy consumption and CO2 emission.
