Abstract
Closure device for a pouring hole (2) having a vertical axis, arranged in the base (11) of a container (1) containing molten metal. The device comprises a flap (3) fixed to the end of a maneuvering arm (3) which is horizontally displaceable to a level below that of the base (11), between a stand-by position and a closure position, and a device for controlling the vertical displacement at least of the end of the arm (31) in order to apply the closure flap (3) on a seating (22) on the periphery of the discharge orifice of the pouring hole (2). The maneuvering arm (31) has a cleaning member (5) located beside the closure flap (3) and centered on the trajectory of the latter. The arm (31) may be stopped in two positions of alignment, with the flap (3) and with the cleaning member (5), respectively, in the axis of the pouring hole (2), and in a position of alignment with the cleaning member, at a level which is adjustable with respect to the seating (22) of the flap (3) in order to remove metal residue adhering to the edge of the discharge orifice.
