Abstract: A closing apparatus for the bottom pouring hole of a casting ladle, comprising a mounting plate mounted on the bottom of the ladle with a head plate resting against it, in which head plate a port is formed to pour out the melt, and further comprising a slide plate supported for pivoting movement about two axes and adapted to be pressed resiliently against the head plate. The slide plate is supported for reciprocating movement inside a housing. The housing is supported by a housing carrier structure, especially between the legs of carrier bracket for the housing, for pivoting movement about a first pivot axis, while the carrier bracket for the housing is supported by the mounting plate for pivoting about a second pivot axis. The first and second pivot axes extend parallel to each other and to the sealing face between the head and slide plates.
