摘要：
This arc start material for electroslag remelting comprises an aggregate of curled turning chips of superalloy. This arc starting method for electroslag remelting comprises starting electroslag remelting by generating an arc between a primary ingot electrode including a primary ingot and an arc start material for electroslag remelting, wherein the primary ingot electrode is energized while contacting with the arc start material for electroslag remelting including an aggregate of curled turning chips of superalloy, and then an arc is generated between the primary ingot electrode and the arc start material for electroslag remelting of superalloy by separating the primary ingot electrode from the arc start material for electroslag remelting of superalloy.
