An electroslag remelting plant includes an ingot mold 4 for forming a block from remolten material, at least one consumable electrode 26, a body having at least one vertically driven electrode rod 20 for the advance of the consumable electrode and a hood 33 disposed above the ingot mold which has at least one concentric opening toward the respective electrode axis. In order to limit the volume over the slag the following is provided: The hood 33 is, with respect to its vertical axis 'A', subdivided into laterally movable sectors 34, 35 each of which is, at a first sealing joint 41, gas-tight connected with its lower edge 40 to top of the ingot mold 4 as far as possible and with its upper edge 39, at a second sealing joint 42, gas-tight sealed as far as possible with respect to the electrode rod. Further, the hood 33 has an interior of such cross section and height that, in its most elevated position, the top end of the at least one consumable electrode 26 is below the second sealing joint 42 of the hood 33.

Electroslag remelting plant including an ingot mold and a hood

An electro-slag remelting furnace having consumable electrodes and a mold for receiving a melt formed from the electrode material; at least one drive motor and at least one spindle and an associated stationary spindle nut for vertical movement of the electrode; at least one guide column, which is provided for vertically guiding the consumable electrodes and which extends parallel with the spindle and relative to which the spindle is rotatable mounted at its two ends; and at least one clamping device for the consumable electrodes.

An electrode clamping device in an electroslag remelting plant has an adjustment device which defines two pivot axes for the electrode holding member which are aligned at right angles to one another and which can be independently controlled for effecting pivotal movement of the electrode holding member about the two axes.

Electrode clamping device for electroremelting plants

An electroslag remelting arrangement for remelting consumable electrodes into ingots, in which the ingot mold power connection is mounted beneath the mold upper edge on the ingot mold or on the mold floor, and is led away downwardly. The electrode current connection has at least two stationary bus bars which extend continuously from the connection point of the ingot mold to the maximum stroke height of the electrode feed device. The bus bars, moreover, run coaxially or quasi-coaxially with respect to the ingot mold, and are electrically connected to the consumable electrode by sliding contacts and connecting leads.

Electroslag remelting apparatus with coaxial current paths

Electrical melting apparatus having a vertical column equipped with guides for at least two electrode feeders each of which have C-shaped carriages partly encompassing the column such that the individual electrode feeders can move past each other without interference.
