The invention relates to an arrangement ( 1, 12, 16 ) for continuously tapping a molten phase, such as matte, from a smelting furnace, such as a flash smelting furnace, said arrangement comprising a matte tapping hole ( 5 ) provided in the furnace wall for discharging the molten phase from the furnace, an overflow tank ( 6 ) for receiving the molten phase ( 4 ), and an overflow edge ( 8 ) provided in the overflow tank for discharging the molten phase, so that in the smelting furnace, in the vicinity of the matte tapping hole ( 5 ), there can be arranged at least one heat-producing element ( 9, 15 ) in order to prevent the molten phase from being solidified. In addition, the invention relates to a method for continuously tapping a molten phase, such as matte, from a smelting furnace, such as a flash smelting furnace, according to which method the molten phase is discharged from the furnace through a matte tapping hole ( 5 ) provided in the furnace wall to an overflow tank ( 6 ), provided with an overflow edge ( 8 ) for discharging the molten phase, so that in the smelting furnace, in the vicinity of the matte tapping hole ( 5 ), there is arranged at least one heat-producing element ( 9, 15 ) in order to prevent the molten phase from being solidified. |
