ABSTRACT Disclosed is a rotary sliding gate valve for metallurgical containers, in particular steel ladles, having a stationary part which includes a re- fractory bottom plate adjacent which is a rotatable part including a ring mount mounted on the stationary part and a refractory sliding plate resting against the bottom plate. The rotatable part of the valve includes a housing partially defined by a rigid cover removably mounted on the ring mount. A pressure plate which receives the sliding plate is located inside the housing. The pressure plate is in direct rotary engagement with the ring mount and is supported on the housing, preferably on the cover, by spring members. The contact pressure of the sliding plate against the bottom plate is therefore independent of the rotary movement, the force being applied directly to the sliding plate. In order to change plates it is merely necessary to remove the housing cover, the rotary drive means remaining permanently engaged on the ring mount.
