Abstract: A method and apparatus are provided for controlling slag in a tilting furnace. The apparatus is mounted on a trough extending from the furnace tap hole and has a reservoir for receiving the flow from the trough. The reservoir has a slag opening and a bottom opening. A passage extends from the bottom opening along a weir which terminates at an elevation above the bottom opening but below the slag opening. The molten metal flows over the weir and out of the device, and the slag is retained in the reservoir and is discharged from the reservoir through the slag opening.

Abstract: Method and apparatus for controlling slag in a tilting furnace is provided. The apparatus comprises a discharge trough, lateral opening, dam, weir, discharge passage, discharge passage gate, and slag gate. The method comprises tilting the furnace to discharge molten metal and slag into the discharge trough, damming and retaining slag in the discharge trough while allowing molten metal to flow through the discharge passage and out of the discharge trough, closing the discharge passage with the discharge passage gate, and opening the slag gate to allow slag to flow out of the discharge trough the lateral opening.

Abstract: A method and apparatus for controlling slag in a tilting furnace are provided. The apparatus comprises a trough having a lateral opening, a discharge outlet, and a passage for defining a non-linear flow path between the lateral opening and the discharge outlet. The method comprises the steps of tilting the furnace to discharge molten metal and slag into the trough, directing the flow of the molten metal through the flow path in the trough, damming and retaining the slag in the trough while permitting the molten metal to flow out of the trough, and discharging the retained slag through the lateral opening in the trough.
