Method and device for the continuous production of steel using metal charge material

A process for continuous production of steel using metal charge materials, comprising the steps of:

• preheating the charge materials in an upper part of a melting vessel and then melting the charge materials in a lower part of the melting vessel with fossil fuels;
• continuously discharging the molten metal into a treatment vessel, in which a desired grade of steel is adjusted;
• introducing gases into the melting vessel from outside for post combustion of process gases, wherein, as the process gases ascend in the melting vessel, the process gases are post-combusted in stages in post-combustion planes arranged above one another;
• and, to accomplish this, also introducing post-combustion gases into an interior of a column of charge materials through an interior shaft that projects into the column of charge material through inlets in a wall of the interior shaft.
