Abstract
A plant for the production of molten metals includes a melting vessel in whose wall burners and optionally oxygen-containing-gas feeding ducts are installed and on whose upper end a charging device as well as a gas evacuation duct receiving the offgases forming enter. In order to enable the continuous charging of the melting vessel by avoiding any unintentional escape of gas from the melting vessel, both the gas evacuation duct and the charging means run into the upper end of the furnace shaft laterally and approximately diametrically opposite each other. The charging means projects into a charging opening brushed over by a gas curtain and an intake chute for charging material is provided below the charging opening in a manner directed towards the center of the furnace shaft. The intake chute forms a projection protruding inwardly like a nose relative to the wall of the furnace shaft and followed by a wall section inclined relative to the lower end region of the furnace shaft and passing over into the wall of the furnace shaft.
