ABSTRACT:
A method to produce stainless steels in electric arc furnaces without secondary processing is disclosed. The method includes three main steps: melting, oxidizing and reducing periods; during all of the steps natural gas is bottom blowed. During the oxidizing period an oxygen blow is accomplished preferably through a vertical lance and during the reducing period a chromium adjustment can be carried out by chromium ore additions.
