Beschreibung
Zusammenfassung:	The invention deals with a method for manufacturing pig iron in an electrical smelting furnace 13 comprising a vessel 20, said method comprising the following successive steps: − loading DRI product in said vessel 20 − melting said DRI product to form a pig iron layer 14 topped by a slag layer 23 and − injecting a desulphurizing reagent directly in said pig iron layer 14. It also deals with the manufacturing of steel from said pig iron and with the associated electrical smelting furnace.
