摘要:
The invention relates to a method for automatic replacement of the discharge shell on a sliding closure (3) by means of a robot (2) for manipulating the sliding closure with a suitable device, wherein the discharge shell can be clamped against the slide plate of the sliding closure by means of a carrier ring that can be detached by rotation. According to the invention, the carrier ring is rotated with a defined torque during the replacement process, whereby the new discharge shell is clamped against the slide plate with a likewise defined clamping force. Thereby the operational reliability of the sliding closure is guaranteed, regardless of any tolerances or other deviations. The device for performing the method includes a gripping lance (26) having clamping jaws (29) for manipulating the discharge shell, and a gripping ring (12) having snap elements (20) for manipulating the carrier ring. The gripping ring (12) can be operated by a hydraulic rotation cylinder (14). A pneumatic cylinder (31) is used for operating the gripping lance (26).

A stopper (6) secured to the lower end of a stopper rod has a faucet (13) with a radial throttle opening (14). A conoidal shut-off face (16) is provided in the stopper (6), above the throttle opening (14). The annular surface of the stopper (13), which penetrates into the outlet bore, provides an additional seal. The stopper (6) can be turned, thus influencing the direction of flow of the outflowing molten mass. The flow can thus be regulated and a high shut-off safety is obtained. Turbulences in the molten mass are further avoided, thus preventing slag from being entrained.

Gegenstand der Erfindung ist eine Ausgußvorrichtung für Schiebersysteme, die beispielsweise bei Stahl-Gießpfannen Anwendung finden, mit einem im wesentlichen zylindrischen Blechmantel (1), der an seiner Innenseite eine feuerfeste Auskleidung (2) aufweist, und einer Befestigungsvorrichtung, mit der die Ausgußvorrichtung an einer Schieberplatte befestigt ist. Eine schnell und einfach an einer Schieberplatte befestigbare Ausgußvorrichtung, die auch nach mehrmaliger Verwendung eine hohe Sicherheit gegen Stahlbruch aufweist wird dadurch geschaffen, daß dar Blechmantel (1) und die Befestigungsvorrichtung einteilig miteinandar verbunden sind und daß dar Blechmantel (1) und die feuerfeste Auskleidung (2) eine gleichbleibende Wandstärke aufweisen.
