Apparatus for making ingots by electroslag remelting

摘要

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 ingot and/or the electrode is provided with or without movement of the electrode itself. Structure for bottom pouring of molten slag is provided. A specific 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.
