Ferrosilicon is a kind of ferroalloy that is composed produced by reduction of silica or sand with coke in the presence of iron. Typical sources of iron are scrap iron or millscale. Ferrosilicons with silicon content up to about 15% are made in blast furnaces lined with acid fire bricks. Ferrosilicons with higher silicon content are made in electric arc furnaces. The usual formulations on the market are ferrosilicons with 60-75%silicon. The remainder is iron, with about 2% consisting of other elements like aluminium and calcium. An overabundance of silica is used to prevent formation of silicon carbide.
Application:
①As deoxidizer and alloy agent in steelmaking industry
②As inoculant and spheroidizing agent in cast iron
③As reducing agent in ferroalloy production
④As displacing agent in the smelting of magnesium
⑤In other applocation fields,milled or atomizing silicon iron powder can be used as suspended phase.
