Abstract

Verfahren und Vorrichtung zum automatischen Füllen einer Stranggießkokille mit (Stahl-)Schmelze, bei dem die Schmelze (13) durch eine mittels eines automatisch betätigten Stopfens (15) verschließbare Bodenausflußöffnung (14) einer Verteilerrinne (10) oder eines Zwischengefäßes geregelt in die Stranggießkokille (18) gegossen wird, wobei während des Füllens der Stranggießkokille (18) der Stopfen (15) vorgege­ bene, insbesondere von der Badspiegelhöhe (19) in der Stranggießkokille (18) abhängige, Auf- und Abwärtsbewegungen (Doppelpfeil 45) ausführt, und zwar gegen die Wirkung einer den Stopfen (15) in Schließstellung drängenden Kraft. Die Auf- und Abwärtsbewegung des Stopfens (15) erfolgt durch ein unmittelbar am oberen Ende desselben angreifendes Stellorgan (B). Die den Stopfen (15) in Schließstellung drängende Kraft wird entweder durch eine konstante Masse (121) oder ein ela­ stisches Element (48 ) erhalten, welches mit steigender Tempe­ ratur den Stopfen (15) in entsprechend zunehmender Weise in Schließstellung zu drängen versucht. Als elastisches Element dienen vorzugsweise geschlossene Gasdruckfedern (48), während das Stellorgan (B) vorzugsweise durch offene Federelemente (49) gebildet wird, die hinsichtlich ihrer Konstruktion den geschlossenen Federelementen (48) entsprechen. Method and device for automatically filling a Continuous casting mold with (steel) melt, in which the Melt (13) by means of an automatically operated Plug (15) closable bottom outlet opening (14) one Distribution channel (10) or an intermediate vessel regulated in the continuous casting mold (18) is poured, during which Filling the continuous casting mold (18) of the stopper (15) level, in particular from the bathroom mirror height (19) in the Continuous casting mold (18) dependent, up and down movements (Double arrow 45) against the effect of a force the plug (15) in the closed position. The Up and down movement of the plug (15) is carried out by a directly at the upper end of the same attacking actuator (B). The force pushing the plug (15) into the closed position is determined either by a constant mass (121) or an ela receive static element (48), which with increasing tempe mature the plug (15) in a correspondingly increasing manner Tried to push closed position. As an elastic element preferably serve closed gas pressure springs (48), while the actuator (B) preferably by open spring elements (49) is formed, the construction of the correspond to closed spring elements (48).
