Claims
- 1. A device for effecting an electroslag remelting process, comprising a baseplate on which is mounted a means for effecting an electroslag remelting process; a molten slag bath set up in said means for effecting an electroslag remelting process; an electrode having one of its ends dipped into said slag bath, its other end being connected to a current source; a protective shield positioned concentrically around the end of said electrode being dipped into said slag bath; said shield being made as a disc of an electrically conductive material which has a higher electrical conductivity than that of the molten slag and whose specific density is lower than that of the slag of said slag bath, said disc overlapping essentially the entire surface area of said slag bath and being arranged in said means for effecting an electroslag remelting process with a clearance between an internal surface of said means for effecting an electroslag remelting process and a side wall of said disc that amounts to at least the thickness of a scull crust on the internal surface of said means for effecting an electroslag remelting process, and with a clearance between the wall of the opening said disc and said electrode that is equal to at least the thickness of a scull crust of said electrode, and said protective shield being made as a disc with through radial conduits running inside said disc from its center to the periphery thereof.
- 2. A device for effecting an electroslag remelting process of claim 1, wherein said protective shield is made as a disc, the thickness of which increases towards its periphery.
- 3. A device for effecting an electroslag remelting process of claim 1, wherein said protective shield is made as a disc, the thickness of which increases towards its center.
