An electrode holder of a multielectrode furnace comprises at least two parts of a support plate, which are insulated electrically from each other. On each part of the support plate some holes are used for fastening the consumable electrodes, while other holes are used for passing the consumable electrodes. The number of holes in each part of the support plate is equal to the number of the consumable electrodes. At least two of said holes are used for fastening the consumable electrodes and have the shape necessary for fastening the inventory heads of the consumable electrodes. The other holes of the support plate are used for passing the consumable electrodes. The parts of the support plate are installed above each other in such a way that the holes for fastening the consumable electrodes of one part of the support plate should be located coaxially above the holes for passing the consumable electrodes of the other part of the support plate. The parts of the support plate are made of a conductive material and are used for feeding the power to the consumable electrodes. Each part of the support plate with the consumable electrodes arranged thereon is connected to the corresponding lead of a power supply source.

Electrode holder of a multielectrode furnace

An apparatus for melting hollow metal ingots during electroslag remelting of consumable electrodes has a hollow chilled mould and a mandrel for moulding the cavity of an ingot which are mounted on a bottom plate at the beginning of the ingot melting cycle. The bottom plate has at least two projections on the working surface thereof. Each projection is shaped as a tooth of a thickness equal to the amount of space between the surface of the inner wall of the chilled mould and the outer surface of the mandrel which moulds the ingot, and the height and the width of each projection are commensurable with the thickness thereof. The projections may be replaceable and may have a trapezoidal cross section. The provision of the projections on the bottom plate prevents the mandrel from being jammed with the ingot being moulded at the beginning of the melting process.
