Summary:A process for producing a steel in at least two converters using a great or substantial amount of an iron-bearing cold material. The iron-bearing cold material and a carbonaceous material are supplied into one of the converters under the presence of a molten iron or a preliminarily treated molten iron and are melted therein under oxygen-blowing to obtain a preliminarily treated molten iron containing a high content of carbon, and the preliminarily treated molten iron is refined in the other converter under oxygen-blowing to obtain a molten steel having the given composition.
