ABSTRACT:
A method and apparatus are provided for controlling slag in a trough of a tilting furnace or in a free-standing tilting vessel. On a tilting furnace, the apparatus is mounted on a trough extending from the furnace tap hole and has a reservoir for receiving flow of molten metal and slag from the trough. The reservoir has a slag opening. One of its walls functions as a dam with 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. The slag is retained in the reservoir and is discharged from the reservoir through the slag opening. In the free-standing tilting vessel, there is a reservoir, slag opening, dam portion, bottom opening, passage and weir, of a substantially similar design as that of the apparatus attached to a trough of a tilting furnace.
