Abstract: An apparatus for supplying gas to a determinate number of injector devices of a melting furnace for the production of metal, including a main feed line, a first secondary feed line and a second secondary feed line which are respectively configured to supply, selectively and in a controlled manner, a process gas, an inert gas and a purge gas to each of the injector devices.
Abstract: Apparatus for the production of metal including a furnace for melting metal provided with a crucible inside which a metal charge is melted. The furnace provides for tapping a liquid metal disposed on the bottom of the crucible and includes a tapping channel for the transfer of the liquid metal from the furnace. The apparatus also includes a delivery unit for delivering inert material (S) having a delivery device for the selective delivery of the inert material (S) into the tapping channel.
