<p>PROBLEM TO BE SOLVED: To improve heat efficiency and a recovery rate of low melting point metal upon fractionating the low melting point metal and high melting point metal from a metal waste material. SOLUTION: A fractionation/melting furnace for metal waste material is adapted such that melt of a metal waste material melted in a furnace 1 including an inclined floor 2 falls into a hot water storage chamber 3 from a final end of the inclined floor 2, and unmelted metal is discharged from a discharge outlet 10 provided on the final end of the inclined floor 2. In the furnace, a deposition part 7 of the metal waste material communicated into the furnace 1 is provided on a higher side of the inclined floor 2, and an insertion hole 6 is provided in a facing part of the furnace 1 to the deposition part 7 which hole is opened and closed with an upper door 5 sliding in the state where it is laid laterally, and further a pusher 8 is provided in the deposition part 76 for pushing the metal waste material to a lower part side of the inclined floor 2.</p> |
