Abstract
A forming method for a disk-shaped component includes: mounting a heated material on a table; applying a load to the material with a forming roll while rotating the table; forming the material into a disk shape using roll forging; and suppressing decrease in temperature of the material during forming using a heat retaining device.
Claims4
A forming method for an impeller disk, the method comprising:
- mounting a material heated beforehand on a table;
- applying a load to an upper surface of the material with a forming roll while rotating the table around a central axis extending in a vertical direction of the table;
- forming the material into a disk shape using roll forging;
- and
- suppressing decrease in temperature of the material during forming using a heat retaining device, wherein
- the heat retaining device is a burner, and
- the material is formed while the material is heated by a flame emitted from the burner towards an inner circumferential side of the upper surface, an outer circumferential side of the upper surface, and a side surface forming an outer circumference of the material rotating on the table.
