A sliding closure () at the outlet of a metallurgic container is provided with a housing (), at least one closing plate arranged therein, a longitudinally displaceable closing plate and a cover (), fastened to the housing () by means of a bracing mechanism (). The closing plates can be pressed against one another by the bracing mechanism () via the cover (). The bracing mechanism () having at least one spring member () is provided with clamping levers () pivotably housed on either side at the housing () and supports () which cooperate with same, with the result that, by pivoting these clamping levers (), the cover () can be fastened to, or released from, the housing. In this way, the closing plates, which often need to be exchanged, can also be braced, always uniformly and optimally, against one another, even after many operational uses.

Slide gate on the spout of a metallurgical vessel

Sliding closure at an outlet of a metallurgical vessel includes a housing fastened to the vessel, a slider unit coupled and longitudinally displaceable relative to the housing, and a respective cassette arranged in the housing and/or slider unit and which operatively retains a refractory closure plate having an opening for passage of medium from the vessel. The closure plate is fixable in and releasable from the cassette by interaction of structure on the cassette and housing or slider unit. This structure includes a retaining element and an elbow lever mechanism on opposite end sides of the cassette, and a corresponding receiver element and snap-in element on opposite sides of the housing or slider unit such that the cassette can be pushed into the housing or slider unit at an angle and fixed therein by pressure through engagement of the elbow lever mechanism with the snap-in element.

Sliding closure at the outlet of a metallurgical vessel

Slide closure for a metallurgical vessel, with two compensation units I and II for equalizing overloads, which may result from the thermal extension and spreading of the fire-proof closure plate thicknesses conditional on manufacturing, and/or from the upper inner shell, wherein the inner shell can also be reduced during operation. The compensation unit I consists of a spring arrangement with fastening screws which can be moved away between the housing and a cover of the housing. The compensation unit II consists, for its part, of a spring arrangement with an insertion frame pressing against the lower closure plate, which insertion frame is fixed to the bottom of the housing with fastening screws.
