An apparatus comprises a cooled mould mounted on a bottom plate and at least two consumable electrodes positioned so that their melting ends are at different levels relative to the bottom plate. The electrodes are connected to respective terminals of the secondary winding of a single-phase transformer and the bottom plate is connected to one of these terminals, with the electrode having a melting end at a higher level, being connected to the same terminal as the bottom plate. The electrodes are melted by passing an operating current, first through the electrode with the melting end being at a lower level to the bottom plate and then by passing the operating current from one electrode to the other, respectively, forming a portion of the casting, having a smaller cross-section, and then a portion of the casting, having a larger cross-section. Thus the present invention is especially well suited for manufacturing workpieces for vital parts such as connecting rods, piston rods, valves for ship engines, etc.

Method and apparatus for electroslag casting of metals

The method includes remelting consumable electrodes in a melting container and effecting a positive action upon crystallization of the ingot in the course of the melting operation, consisting in that a cooled body is brought into contact with the molten metal constituting the metal bath and the contact is maintained till the melting operation is complete by moving the cooled body at a speed close to the melting rate. On completion of the melting operation, the cooled body is extracted from the metal bath. The cooled body may be made in the form of a float or of an extension widened at the bottom and fixedly attached to a movable mold.

Method and apparatus for producing a solid-section ingot by electroslag

An electroslag remelting apparatus for producing ingots includes a mould and an electrode feeding device comprising a lower holder with a roller feeding means and an upper holder in the form of a rotatable drum with a vertical shaft. The drum has through sockets to accommodate electrode blanks and gates to support the blanks. The electrode feeding device comprises also a means for joining together the consumable electrode and the electrode blank brought into abutting contact with the aid of said holders, which ensures continuous feed of the electrode into the mould cavity.

Electroslag remelting apparatus for producing ingots

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.

Electroslag remelting apparatus having relative mold movement and

In a plant a carrier for withdrawing an ingot is a drum, rotatably mounted about the horizontal axis thereof, adjacent to the side of a mould near its wall shaping the internal surface of the ingot and coaxial with the wall, with a base plate having a dummy bar and an electrode holder being fastened to the drum shell; the electrode holder being electrically insulated from the drum and carrying at least one electrode curvilinear in shape and encompassing a part of the drum and having a clearance therewith to preclude electrical contact between the drum and the electrode; the drum, while turning, serving also as a mechanism for feeding the electrode into the mould melting space.
