ABSTRACT:
A rotating closure device for a runout opening in a base of a metallurgical vessel for preventing access of gases reacting with a melt. The device includes an upper closure plate (3) positioned at an end side of a drain block (1) and a lower closure plate (4) at the outlet (2). The upper closure plate (3) is provided with at least two through-holes for meeting at least two channels (7, 8) in the drain block (1), which channels (7, 8) extend parallel to an axis of rotation of the device. The lower closure plate (4) is provided with at least one through-hole for meeting at least one channel (6) in the outlet. The at least two chapels (7, 8) meet at least one channel (6) via a connection between the upper and lower closure plates (3, 4).
