Abstract
A method for forming a foamy slag in an electric arc melting furnace during the production of a ferrous alloy may include: (a) melting a metal charge in the electric arc furnace to obtain a molten metal bath including a layer of a floating slag; (b) introducing a foamy slag forming agent into the furnace to foam the floating slag. The agent may be a composite material in granular form which includes at least one thermoplastic polymeric material and at least one biogenic carbonaceous material.
