Abstract

Eine Vorrichtung zum Verschließen eines Bodenabstichs eines metallurgischen Gefäßes (1) für flüssigen Stahl, insbesondere eines Elektroschmelzofens (2), mit einer verschiebbaren Verschlussplatte (8) und bei dem das Abstichloch (7) mit feuerfestem Material aufgefüllt wird, das mittels eines Presskolbens (11a) eingedrückt wird, vermeidet bogenförmige Presskanäle und das senkrechte Einführen von mit Stampfmasse umhüllten Kartuschen aus FF-Material, indem der Presskolben (11a) mittels eines in mehreren Stationen (14) horizontal verfahrbaren Wagens, in denen Granulat (15) in den Zylinder (11 b) eingebracht und vorbereitet wird, auf einer mit dem Abstichloch (7) fluchtenden Presskolben-Achse (11c) senkrecht von unten nach oben verstellbar und dabei das Granulat (15), das Abstichloch (7) voll ausfüllend unter Druck einbringbar ist.

Figure 00000001
A device for closing a bottom tapping of a metallurgical vessel (1) for liquid steel, in particular an electric melting furnace (2), with a displaceable closing plate (8) and in which the tap hole (7) is filled with refractory material which is pressed by means of a press piston (11a ) is pressed in, avoids arc-shaped press channels and the vertical insertion of cartridges made of FF material encased in ramming mass by pressing the plunger (11a) by means of a carriage which can be moved horizontally in several stations (14), in which granulate (15) into the cylinder (11 b) is introduced and prepared, on a press piston axis (11c) aligned with the tap hole (7) vertically adjustable from bottom to top and thereby the granules (15), the tap hole (7) can be filled completely under pressure.
