Electric Arc Furnace Process an overview ScienceDirect
Steel is produced by using two types of raw materials: hot metal or pig iron, and steel scrap, and through two types of processes: basic oxygen furnaces (BOF) or basic oxygen steelmaking and electric arc furnaces (EAF) In BOF steelmaking, about 75% of iron comes from the hot metal produced by blast furnace process, the remaining 25% of the raw materials is steel scrapA technology for adding liquid pig iron to a DSP10017 furnace has been developed, tested, and introduced commercially The technology reduces the consumption of electric power by 44–55 kW·h/ton steel (to 4063 kW·h/ton) and shortens the heat by an average of 10 min The duration of the trial heats was 1 h, 51 minCertain technological parameters of the steelmakingUse of liquid pig iron in electricarc furnaces | SpringerLink
