摘要:
A method of producing a forged product is described, in which a forging component (6) is hot-forged using a lower die (1) and an upper die (2). The method includes a first process in which an die face (3) of the lower die (1) is covered with a first glass lubricant (5); a second process in which the lower die (1) is heated; a third process in which at least a part of the forging component (6) is covered with a second glass lubricant (7); a fourth process in which the forging component (6) is heated to a temperature that is higher than a heating temperature of the lower die (1) in the second process; and a fifth process in which the forging component (6) is placed on the die face (3) and hot forging is performed using the lower die (1) and the upper die (2).
