  • Patent number: 5238484
    Abstract: A plant for the production of molten metals, includes a melting vessel and a metallurgical vessel receiving the melt from the melting vessel for aftertreating the melt and closed by a lid. The melting vessel has a tap opening for the melt provided on the bottom level of the melting vessel and located on the periphery of the melting vessel. The tap opening is positioned above a pour-in opening of the metallurgical vessel. In order to ensure a continuous melting procedure, the pour-in opening of the metallurgical vessel following the melting vessel is provided above a melt guiding chute arranged within the metallurgical vessel.

  • Patent number: 5190719
    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.
