Abstract
A method for manufacturing hollow ingot for retaining ring of large generator by electroslag remelting, comprising the following steps: (1) preparing consumable electrode assemblies; (2) melting slag into molten slag; (3) inserting one consumable electrode assembly into an electroslag remelting hollow ingot mold; (4) switching on two transformers; (5) pouring the molten slag into the electroslag remelting hollow ingot mold; (6) forming a current circuit among a stub, the consumable electrode assembly and a water-cooled bottom plate; (7) forming a current circuit among the upper segment, the water-cooled bottom plate and the transformer; (8) regulating the output current and voltage of the two transformers; (9) starting a withdrawing device to withdraw; (10) exchanging the consumable electrode assembly; (11) inserting a subsequent consumable electrode assembly into the molten slag, and repeating steps (8) to (10) until withdrawing is completed.
