APPARATUS FOR ELECTROSLAG REMELTING OF CONSUMABLE ELECTRODES

The invention relates to the field of electrometallurgy, and in particular to a method for electroslag remelting. The method is characterized in that it utilizes a transformer power supply means, which can be three-phase or which can consist of several single-phase transformers. The method uses seco...

Beschreibung
Zusammenfassung:	The invention relates to the field of electrometallurgy, and in particular to a method for electroslag remelting. The method is characterized in that it utilizes a transformer power supply means, which can be three-phase or which can consist of several single-phase transformers. The method uses secondary windings of the transformer power supply and incorporates center tappings of those secondaries interconnected to provide for an equality of the line speeds of melting the electrodes and for a uniform temperature field within the slag bath. The method can be utilized in the process of producing unique hollow or solid ingots and slabs of high-grade steels and alloys having a weight of 200 tons and higher.
