ABSTRACT:
A metallurgical furnace installation is disclosed which includes a metallurgical furnace for holding a metal melt therein, a melt launder, and a drain launder. The furnace has an outlet for discharging the melt and a drain hole for draining the melt remaining in the furnace. The drain hole is formed at a bottom of the furnace so as to be openable and closable. The melt launder has one end connected to the outlet of the furnace and is inclined downwardly in a direction away from the furnace, whereby the melt in the metallurgical furnace is tapped therethrough toward the other end. The drain launder has one end connected to the drain hole and the other end connected to the melt launder, and is inclined from the one end toward the other end, whereby the drained melt flows therethrough into the melt launder.
