The most used are submerged arc furnaces (SAFs) and resistance-heating furnaces (RHFs), where heating of the charge, slag, and alloy proceeds by the application of electric current. In these electric furnaces, the tips of electrodes protrude into the furnace hearth and be hidden by a burden (charge) of raw materials, which have been fed ...

Ferrosilicon production is a nearly slag-free process (the silicate-based slag amount does not exceed 3% to 5% of the alloy mass). However, the tapping of ferrosilicon and slag through one tap hole might beplicated by changes in the slagposition.

The production of ferroalloys and alloys like ferronickel, ferrochromium, ferromanganese, silanganese, ferrosilicon and silicon ismonly carried out in submerged arc furnaces. Submerged arc furnaces are also used to upgrade ilmenite by producing pig iron and a titania-rich slag. Metal containing resources are smelted in this furnace type using fossil carbon as a …
