In an electroslag remelting apparatus comprising electrode holders adapted to hold at least two consumable electrodes connected to different terminals of an a.c. power source, the mould and the bottom plate are electrically connected to each other and, through rectifiers, to the a.c. power source, the rectifiers being connected to the same terminals of the a.c. power source as the electrode holders. The rectifiers are so connected into the circuit as to provide a flow of only direct current through the bottom plate and mould towards the a.c. source through said rectifiers.

Apparatus for electroslag remelting of consumable electrodes

Premelted slag and metal of a specified composition are poured into a recacle. Thereafter, electroslag remelting of consumable electrodes is carried out in a slag pool formed in the receptacle. As the poured-in metal and remelted metal solidify, a non-split workpiece is being formed of two parts, of which one part is formed of the poured-in metal and the other one of the consumable electrode being melted down. To produce hollow billets with bottom parts according to the method, described above, the molten metal is taken in an amount determined by the mass of the bottom part. The molten slag and molten metal are poured into a working space of an apparatus for producing cast hollow billets, which working space is defined by a stationary bottom plate, the mould walls and by a mandrel. This very working space is also used for effecting electroslag remelting of consumable electrodes to form the remainder part of the hollow billet.

A contactless inductance interface pickup, having within an external housing an auxiliary housing installed, and formed as a pot, with at least the bottom thereof being constructed from a non-magnetic material, and a clearance between the external housing and the auxiliary housing wherethrough a cooling agent flows around the pickup. Inside the auxiliary housing, in immediate proximity to the bottom thereof, a magnetic circuit is disposed with at least one measuring winding and at least one energized winding.

Contactless inductance pickup for detecting the interface of two media

An electroslag remelting furnace with relative displacement of a mould and an ingot being cast is provided with an electric control circuit for controlling the displacement of consumable electrodes, an electric control circuit for controlling the displacement of the mould, and an electric control circuit for controlling the power input in accordance with the rate of the ingot remelting, all of the electric circuits being electrically coupled to one another.

A non-contact inductive pickup for determining the interface between two media. The media have different specific density, different specific resistance and at least one of the media is electrically conductive and non-magnetic. The pickup comprises two open U-shaped magnetic circuits disposed parallel to each other and embraced by excitation and measuring windings.
