A stopper arrangement for controlling the flow of molten metal or the like through the bottom opening of a ladle. The stopper arrangement is supported for movement about a longitudinal axis between its opened and its closed positions. The supporting arrangement for the stopper element is such that the element may shift transversely with respect to the longitudinal axis but will always move in a direction parallel to the longitudinal axis as it is opened or closed. The stopper element is also supported for oscillation and is positively rotated when in its closed position for insuring good sealing engagement with the opening.
