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.

A mould for the electroslag casting of faceted metal ingots has longitudinal flutes on the internal surfaces of at least two walls thereof. The depth of these flutes decreases in a horizontal direction from the middle of the walls to the corners of the mould chamber.

Mould for electroslag casting of faceted metal ingots

A furnace for the electroslag remelting of consumable electrodes in a single mould, having a common slag bath and a zone for shaping simultaneously several ingots separated into parts with the aid of at least one dividing wall.

Furnace for electroslag remelting of consumable electrodes

An electroslag remelting plant comprises a cooled mould, a base plate adapted for shaping the bottom part of an ingot, a single-phase transformer having a secondary winding with a midpoint, and two similar groups of electrodes, each one of the two groups of electrodes comprises at least two electrodes and being connected to one of the ends of the secondary winding of the single-phase transformer so that each two proximate adjacent electrodes have an opposite polarity.
