A launder for discharging melt from a metallurgical furnace is disclosed which includes a launder body having one end connected to the furnace. The launder body defines a fluid passageway for allowing the melt, flowing from the metallurgical furnace into said one end, to flow therethrough in a direction away from the furnace. The launder body includes a threshold portion for determining the melt level in the furnace, above which the melt in the furnace begins to flow into the launder body. The launder body further includes a closing portion constructed to receive a closing material thereon to close the fluid passageway of the launder body. The closing portion is arranged at a position displaced downstream with respect to the threshold portion and has a bottom lower than the threshold portion. Additionally, a metallurgical furnace installation using the above launder is disclosed, in which a pair of the launders are arranged while ensuring space for casting or removing operations of castable. |
