    • Die Erfindung bezieht sich auf eine Stahlstranggiessanlage für Knüppel- und Vorblockformate mit im wesentlichen rechteckigem Strangquerschnitt. Um das Stranggefüge insbesondere in den Eckbereichen zu verbessern, Spiesskantigkeit, Risse und schädliche Massabweichungen des Strangquerschnittes auszuschalten und um hohe Durchsatzleistungen je Strang bei niedrigen Investitions- und Betriebskosten zu erreichen, sollen die Ausrundungen der Hohlkehlbogen (12, 12', 13, 13') im Formhohlraum mindestens 10 %, vorzugsweise 15 % oder mehr der Seitenlänge (16) des Strangquerschnittes betragen. Im weiteren soll sich in Stranglaufrichtung mindestens entlang einer Teillänge der gesamten Kokillenlänge der Krümmungsgrad 1/R des Hohlkehibogens (12, 12', 13, 13') verkleinern. Dadurch soll eine gezielte Spaltaufhebung zwischen der Strangschale und der Kokillenwand bzw. eine gezielte Strangschalenumformung im Bereich des Hohlkehlbogens steuerbar sein. Die Stranggiessanlage soll im weiteren unmittelbar an die Kokille anschliessend eine strangabstützungsfreie Sekundärkühlzone oder eine in ihrer Stützbreite­ und/oder Stützlänge reduzierte Stützführung in der Sekundärkühlzone aufweisen.

    • The invention relates to a method for producing metallic ingots or strands, especially from steel and Ni and Co based alloys, by melting self-consuming electrodes in an electroconductive slag bath, using an alternating current or a direct current in a short water-cooled mould which opens downwards, via which an electric contact can be produced for the slag bath. The supplied melt current is passed via the consumable electrode, the bottom plate, the remelt ingot and the melting bath, and optionally at least one electroconductive element of the mould, to the slag bath. The current distribution can be regulated in a controlled manner and the return circuit of the melt current passes back via at least one other electroconductive element of the mould, which is electrically isolated in relation to a first part of the mould which forms the remelt ingot. The proportion of the entire melt current supplied via the bottom plate is selected between 0 and 100 %. The device for carrying out said method uses a short, water-cooled mould having a bottom plate for creating a remelt ingot, and having at least one electroconductive element which is provided in the region of the slag bath. Said element is isolated in relation to the lower region of the mould, which forms the remelt ingot, and/or in relation to other electroconductive elements.

    • The invention relates to a method and to a device required for carrying out said method for the continuous production of electroslag-casted or remelted billets or ingots from metal, especially from steels and Ni and Co base alloys in a water-cooled ingot mold (10) that is open towards the bottom. The billet (20) that is issued from the bottom of the ingot mold (10) is forced against a guide element (24, 24a) that is stationary with respect to its position to the ingot mold axis (A) by at least one clamping element (26) that is located opposite said guide element in such a manner that the areas of the billet surface that contact the guide or clamping elements (24, 26) change within short time intervals. At least one of those elements is driven to draw the billet while the other elements follow the movement of the billet. The method is also characterized in that at least one of the elements mentioned can be used to establish a contact with a source of current.

    • The invention concerns a device for continuous casting in vertical charge of a melting metal in the form of slabs, using a copper ingot mould (1) extended by a preheater (2) made of refractory material, the preheater (2) being positioned above the ingot mould (1) such that the liquid steel level, or meniscus (S), is located during the continuous casting operation in said refractory material preheater (2) and not in the copper ingot mould (1) proper. Between the copper ingot mould (1) and the preheater (2) is arranged a joint element made of refractory material consisting of bars (3), (4), (5), (6), (7), (8). The bars are positioned such that their assembly defines a joint element with an internal shape similar to that of the ingot mould and whereof the inner surfaces are the extension of the ingot mould corresponding inner surfaces, with a choice of dimensions such that the ratio of a bar transverse cross-section, expressed in mm , to the length of said bar, expressed in mm, is not less than 2.4 mm. Moreover, the bars are parallelepiped in shape and their cross-section has a height/length ratio ranging between 0.4 and 0.6. Each bar (4), (6) is supported against a rear stop (12), (13) serving to position it in perfect alignment, allowing for the mechanical assembly clearances, with the ingot mould surface whereof it constitutes the extension and prevent it from being pushed backwards by the slab, and each bar (4) is machined (R) to receive a maintaining clamping claw (9), the latter ensuring the double function of pressing the bar vertically so that it remains in contact with the ingot mould top edge during the oscillating motion of the latter, and to prevent the bar from moving away from the alignment with the ingot mould surface whereof it is an extension by moving towards the slab centre, in particular at the start of the operation of continuous casting in vertical charge.
