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

In melting down at least one consumable electrode in an electroslag remelting furnace, a gas is blown into the molten slag in such a manner that the gas flows in a jet towards the consumable electrode portion immersed into the slag to create a slag flow around said portion and thereby accelerate the melting-down of the electrode. The method efficiently eliminates an unbalance in the melting-down rates of two or more electrodes by blowing in the gas at different or controlled flow rates towards every electrode.

Method for electroslag remelting of metals

A mould wall has one or a plurality of cylindrical or tapered inserts positioned therein. The outer lateral surfaces of the inserts are provided with longitudinal through grooves bounded by the wall of the opening wherein the insert is positioned, the groove and the wall forming passages for feeding gas into the slag pool zone in the mould. The insert may consist of a plurality of parts coaxial within one another, the outer lateral surfaces of the parts having longitudinal through grooves similar to those on the insert outer surface. The mould construction according to the invention simplifies the technique for manufacturing ducts for feeding gas into the slag pool zone and raises the intensity of interaction between the gas and the liquid pool by feeding gas in the form of small bubbles having large total surface area.

Electroslag remelting mould

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.

Apparatus for electroslag remelting of at least one consumable electrode in a cooled mold assembly with a cooled bottom plate having mechanism accomplishing relative movement between at least a part of the mold assembly and the ingot being formed during forming of the ingot. Movement of selective parts of the mold assembly relative to the ingots and/or the electrode is provided with or without movement of the electrode itself. Structure for bottom pouring of molten slag is provided. A specified mold assembly has, as an element, a cooled core device enabling making hollow ingots, in which case the hollow core device can be moved axially, reciprocated axially and reciprocally rotated during forming of the ingot. Electrical power for the electroslag remelting can be connected between the consumable electrode and any or all elements of the mold assembly.
