More Information
Summary:A converter for the production of steel from solid and/or liquid charging substances, such as pig iron and/or scrap and/or sponge iron, includes a refractorily lined refining vessel, a refining device for feeding oxygen or an oxygen-containing gas, and a heating device. In order to obtain the maximum output possible at high scrap charging as well as a high purity of the steel, the heating device includes at least one self-consuming graphite electrode and the refining device, independent of the heating device, either is formed by an oxygen-blowing lance or includes oxygen-containing bottom and/or lateral tuyeres located below the melt bath level.
