ABSTRACT:
A method of making steel in an electric arc furnace is provided. The method comprises the steps of charging a steelmaking furnace with an iron source, wherein the iron source is melted and refined in the steelmaking furnace during a campaign, providing a source of lime that is screened by a first screening device, compacting the lime material adjacent to the steelmaking furnace to a predetermined size, charging the compacted lime to the steelmaking furnace within a short period of time to avoid degradation of the compacted lime, and adding additional fluxing agents and additives to the steelmaking furnace to produce refined steel in the campaign.
