<p>A mechanical skimmer for removing dross from the surface of molten metal in a furnace is disclosed which includes a dross pusher head which is reciprocated across the molten metal in the furnace from one side of the furnace to the other, in order to push the dross on the top surface of the molten metal towards one side of the furnace. A pivotally mounted scoop is mounted on or adjacent the furnace along the side to which dross is pushed by the pusher head, and has an open side which is normally positioned at least partly within the furnace opposite the pusher head to receive dross pushed by the head. The scoop is pivotable from its normal position within the furnace through a predetermined angle to a tilted position above the upper edge of the furnace, thereby to discharge dross contained in the scoop into a receptacle or conveyor located outside of the furnace.</p> |
