Abstract

In a slide valve closure for the casting of a metal melt a slider plate and a stationary closure part are braced against each other by means of spring units or by other means. There is provided a casing framework attachable to a mould or the like, in which is fixed a detachable casing part on which the spring units are held and in which the stationary closure part and the slider plate can be accommodated. This allows safe operation and simple and rapid mounting and dismounting of the slide valve closure.
