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.
