Abstract
A method and apparatus of controlling the pouring spout of a tundish for molten metals, including a slide valve composed of a valve member mounted for movement between a head plate disposed on the underside of the tundish and a discharge member. For preventing in a particularly effective way any freezing of the molten metal and for avoiding any static shadow corners the valve member and/or the head plate or both in the closed and/or open or part-open position thereof are moved in such a way that a two-dimensional relative movement perpendicular to the longitudinal axis of the pouring spout is generated between the valve member and the head plate.
