Abstract Modelling the production of silicon in a submerged arc furnace (SAF) requires accounting for wide range timescales different physical and chemical processes: electric current which is used to heat varies over timescale around $10^{-2}\,$ s, whereas flow consumption raw materials occurs several hours. Models generally either include only fast-timescale, or slow-timescale processes. In p...

The chapter covers general issues related to power quality in Electric Arc Furnaces. The use of electric arc furnaces (EAF) for steelmaking has grown dramatically in the last decade. Of the steel made today 36% is produced by the electric arc furnace route and this share will increase to 50 by 2030. The electric arc furnaces are used for melting and refining metals, mainly iron in the steel pro...
