 Erst zu diesem Zeitpunkt wird die Kokille-l-samt dem   Dorn --7-- ausgehoben   oder die Bodenplatte   --2, 2'--abgesenkt, u. zw.   wie üblich, mit jener Geschwindigkeit, die dem Blockwachstum entspricht. 



   Mit erfindungsgemässen Vorrichtungen gesammelte Erfahrungen haben erwiesen, dass das Festklemmen des Dornes am Anfang eines Umschmelzvorganges nicht mehr auftritt. 



     PATENTANSPRÜCHE   : 
1. Vorrichtung zum Herstellen von Metallhohlblöcken durch Elektroschlacken-Umschmelzen verzehrbarer Elektroden, bestehend aus einer kühlbaren Kokille, die einen formgebenden unteren Abschnitt und einen oberen Abschnitt zur Aufnahme eines Schlackenbades aufweist, einer relativ zu der Kokille bewegbaren Bodenplatte, einem in den formgebenden Abschnitt einführbaren Dorn und einem hebund senkbaren Elektrodenhalter zum Befestigen der verzehrbaren Elektroden,   dadurch ge-     kennzeichnet,   dass an der Bodenplatte (2, 21) zwei oder mehrere, mit ihren Seitenflächen die Innenwand (5) des formgebenden Abschnittes und die Mantelfläche (6) des Dornes (7) berührende Vorsprünge (3, 3') angeordnet sind, wobei der Abstand zwischen zwei benachbarten Vorsprüngen (3, 3')

   ein Vielfaches ihrer Erstreckung in Umfangsrichtung des von der Innenwand (5) und der Mantelfläche (6) begrenzten Formhohlraumes (4) beträgt.

 Only at this point in time is the mold-1-including the mandrel --7-- lifted or the base plate --2, 2 '- lowered, and the like. between, as usual, at the rate that corresponds to the block growth.



   Experience gained with devices according to the invention has shown that the mandrel is no longer jammed at the beginning of a remelting process.



     PATENT CLAIMS:
1. Apparatus for producing hollow metal blocks by electroslag remelting of consumable electrodes, consisting of a coolable mold which has a shaping lower section and an upper section for receiving a slag bath, a base plate movable relative to the mold, a mandrel that can be inserted into the shaping section and a liftable and lowerable electrode holder for fastening the consumable electrodes, characterized in that two or more, with their side surfaces, the inner wall (5) of the shaping section and the outer surface (6) of the mandrel (7 ) contacting projections (3, 3 ') are arranged, wherein the distance between two adjacent projections (3, 3')

   a multiple of its extension in the circumferential direction of the mold cavity (4) delimited by the inner wall (5) and the lateral surface (6).

Claims (1)

Vorsprünge (3') in Ausnehmungen (13) der Bodenplatte (21) eingesetzt und befestigt sind (Fig. 4, 5). Projections (3 ') are inserted and fixed in recesses (13) of the base plate (21) (Fig. 4, 5). 3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Vorsprünge (3) bei Formhohlräumen (4) mit von Kurven, insbesondere von Kreisen begrenztem Querschnitt in wenigstens annähernd gleichen Abständen voneinander angeordnet sind (Fig. l bis 3). 3. Device according to claim 1 or 2, characterized in that the projections (3) in the case of mold cavities (4) with a cross-section delimited by curves, in particular circles, are arranged at at least approximately equal distances from one another (FIGS. 4.
