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.

Method for producing a non-split metal workpiece formed as a cast hollow

An ingot electroslag remelting apparatus is provided with two electrode hers for feeding consumable electrodes into the melting space of a mould. The electrode holders are secured to ends of booms rotatable in a vertical plane. The booms are mounted on carriages slidable in vertical guides. The proposed invention reduces the time necessary to replace a melted consumable electrode by a fresh one in the melting space of the mould.

Ingot electroslag remelting apparatus

The apparatus has a mould comprising conjugate stationary and movable parts, said movable part being a drum with a horizontal axis of rotation and having a drive for the rotation thereof. A bottom plate is fixedly attached to the drum and serves to strip the blank being cast from the mould through the action of said drum. The apparatus is provided with a carriage for the displacement of a consumable electrode relative to said drum, which is rotatably mounted on the drum shaft. The carriage has a separate drive for its rotation on the shaft and carries a holder with the consumable electrode.

Apparatus for electroslag castings of semicircular blanks

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

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.

Plant for electroslag melting of hollow ingots shaped as non-closed

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.

Apparatus for melting hollow metal ingots during electroslag remelting

A mould for casting at least one component of a complex-shaped metal article, the mould having in the fusion area at least one hole hole fitted from the mould interior with a slot whose geometric dimensions ensure the formation of a slag blanket in the volume which is required for a uniform heat removal in the fusion area. The number of the holes correspond to the number of the article components to be joined by fusion and the geometric dimensions and contour of the holes matching those of the article components to be bonded by the application of a fusion process.
