Abstract
A method of and apparatus for producing consumable electrodes with large diameters to be used for remelting involves assembling the electrode of individual longitudinal parts adjacently arranged. Which longitudinal parts are continuously cast in special moulds as strands having polygonal cross sections. The parts are assembled so as to form a polygonal overall cross section, and their end faces are welded together with a common gripping head for the electrode holding device.
Claims1
In a method of producing a consumable electrode of large diameter, having a substantially uniform chemical composition over its entire length and total cross section, to be used for remelting, for example electroslag remelting, said consumable electrode being assembled of at least two adjacently arranged individual longitudinal parts, the improvement which comprises the steps of:
- continuously casting said at least two longitudinal parts in a manner so as to form strands having polygonal cross sections,
- assembling said at least two individual longitudinal parts so as to form a polygonal overall cross section,
- providing a common gripping head for an electrode holding means, and
- welding together the end faces of said at least two individual longitudinal parts with said common gripping head.
