Method of producing pipes with crack arresters

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 electroslag remelting plant according to the invention, comprises a double-mast single-phase furnace connected to a three-mast three-phase furnace through water-cooling and gas suction systems, with at least one mast of the three-mast three-phase furnace, on which an electrode holder is fixed, being spaced at such a distance from the double-mast single-phase furnace which ensures the melting of an ingot into a common mold. Such plant allows melting large-size slab ingots and features high versatility ensuring simultaneous melting of different ingots with each electrode holder serving its mold.
