Zusammenfassung:	A method for preparing and feeding metal scrap to an electric smelting furnace for making steel and an apparatus for performing the method. The method comprises: - a step of preparing the scrap in packs (2); - a step of preheating the packs (2) of scrap in a preheating furnace (10) that is distinct from the electric smelting furnace (30); - a step of extracting the preheated scrap packs (2) from the preheating furnace (10) and conveying them toward an electric smelting furnace (30); - a step of introducing the packs (2) of preheated scrap into the liquid metal bath (50) of the electric smelting furnace (30).
