Plant for the production of molten metals and method
First Claim
1. A plant for producing molten metals comprising an upstanding melting vessel characterized by a downwardly extending shaft portion which terminates into a bottom for receiving metal melted in said melting vessel, said bottom having a tap opening at a peripheral portion thereof through which molten metal is removed, said plant including a metallurgical vessel having a roof or lid cooperatively coupled to the bottom of said melting vessel such that the tap opening of said bottom is disposed above and communicates with a pour-in opening located at a peripheral portion of the roof or lid of said metallurgical vessel, said vessel having a closed bottom,said metallurgical vessel including a melt-guiding chute having an upper end and a lower end disposed within said metallurgical vessel along an internal wall thereof extending downwardly from its upper end from a region of the pour-in opening of the metallurgical vessel with its lower end terminating above the bottom of said metallurgical vessel where the molten metal is subsequently confined for further metallurgical treatment.

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.

18. A process for producing refined molten metal in a plant comprising an upstanding melting vessel characterized by a downwardly extending shaft portion which terminates into a bottom for receiving metal melted in said melting vessel, said bottom having a tap opening at a peripheral portion thereof through which molten metal is removed, said plant including a metallurgical vessel having a roof or lid cooperatively coupled to the bottom of said melting vessel such that the tap opening of said bottom is disposed above and communicates with a pour-in opening located at a peripheral portion of the roof or lid of said metallurgical vessel, said metallurgical vessel including a melt-guiding chute having an upper end and a lower end disposed within said metallurgical vessel along an internal wall thereof extending downwardly from its upper end from a region of the pour-in opening of the metallurgical vessel with its lower end terminating above the bottom of said metallurgical vessel where the molten metal is subsequently confined for further metallurgical treatment.
said process comprising continuously conveying said melt from said melting vessel via its tap opening into said metallurgical vessel through its pour-in opening, refining the molten metal in said metallurgical vessel, and then discontinuously drawing off the molten metal from the metallurgical vessel after the refining thereof.
