  • Device for effecting electroslag remelting processes
    Patent number: 4192370
    Abstract: The present invention relates to a method of and a device for effecting electroslag remelting processes.While effecting an electroslag remelting process by the proposed method an electrode is dipped into a slag bath. Electric current is passed through the electrode and slag bath, heating the slag to a melting point of said electrode. Upon establishing the molten slag bath and a metal pool said electrode is shielded by lowering on the surface of the molten slag bath a disc with an opening for the passage of said electrode so that the disc will float in the slag without coming in contact with the metal pool. A device for effecting electroslag remelting processes, comprising a baseplate mounting a means for effecting an electro slag remelting process accommodating a slag bath and an electrode that is dipped thereinto and is encompassed with a protective shield made as a disc of material whose specific density is lower than that of the slag of said slag bath.

  • Plant for and method of electroslag remelting of metals and alloys
    Patent number: 4145563
    Abstract: A plant for electroslag remelting of metals and alloys, comprising a cooled mould mounted on a cooled base plate where a slag bath is arranged. Introduced into said slag bath is one end of a consumable electrode, its other end being connected to one of the poles of a current supply source. The plant has at least one non-consumable electrode that is connected to the other pole of the current supply source in series with the consumable electrode. A method of electroslag remelting of metals and alloys in which an electric current is passed through the consumable electrode the slag bath and the non-consumable electrode during the remelting process.

  • Method of electroslag remelting processes using a preheated electrode shield
    Patent number: 4132545
    Abstract: The present invention relates to a method for effecting electroslag remelting processes.While effecting an electroslag remelting process by the proposed method an electrode is dipped into a slag bath. Electric current is passed through the electrode and slag bath, heating the slag to a melting point of said electrode. Upon establishing the molten slag bath and a metal pool said electrode is shielded by lowering on the surface of the molten slag bath a disc with an opening for the passage of said electrode so that the disc will float in the slag without coming in contact with the metal pool.
