Metallurgical furnace installation

A metallurgical furnace installation comprising:

• a first metallurgical furnace for holding a metal melt therein, said metallurgical furnace having an outlet for discharging the melt and a drain hole for draining the melt remaining in said metallurgical furnace, said drain hole being formed at a bottom of said metallurgical furnace so as to be openable and closable;
• a melt launder having one end connected to said outlet of said metallurgical furnace and being inclined downwardly in a direction away from said metallurgical furnace, whereby the melt in the metallurgical furnace is tapped therethrough toward the other end;
• a drain launder having one end connected to said drain hole and the other end connected to said melt launder, said drain launder being inclined from the one end toward the other end, whereby the drained melt flows therethrough into said melt launder;
• and
• a second metallurgical furnace having an inlet, the other end of said melt launder being disposed at said inlet of said second metallurgical furnace, said inlet of said second metallurgical furnace having an elevation lower than the bottom of the first-mentioned metallurgical furnace.
