Problems solved by technology
Since the superalloy is characterized by great deformation resistance, the die forging pressure of the solid cake billet is relatively high, so not only the pressure on the die is increased, but the life of the die is reduced, and the tonnage of the required equipment is increased.
In addition, due to the small deformation of the metal at the core of the mold, the product quality is not easy to guarantee

Embodiment Construction
[0006] The present invention will be further described below in conjunction with specific embodiments, so as to help understand the content of the present invention.
[0007] Taking the processing of a turbine disk die forging with a hole in the center as an example, before the die forging process, according to the position and size of the center hole of the turbine disk die forging, the center hole is turned on the superalloy die forging cake to remove the most microstructure. The poor core metal is then subjected to die forging to obtain a turbine disc die forging.

The invention discloses a method of processing a high-temperature alloy forging part with a center hole. The invention is characterized in that the center hole of the high-temperature alloy forging part is made before forging to remove the metal of inferior structure positioned at the center; and then forging is processed. Useful life of the mould can be prolonged and quality of the mould can be guaranteed by adopting the method.
Description
technical field [0001] The invention relates to the field of metal material processing, in particular to a processing method for high-temperature alloy die forgings. Background technique [0002] At present, for high temperature alloy die forgings, no matter whether the die forgings have a center hole or not, they are all directly die forged from solid cake blanks. Since the superalloy is characterized by great deformation resistance, the die forging pressure of the solid cake billet is relatively high. Therefore, not only the pressure on the die is increased, but the life of the die is reduced, and the tonnage of the required equipment is increased. In addition, due to the small deformation of the metal in the core of the mold, the product quality is not easy to guarantee. Contents of the invention [0003] In view of the above-mentioned problems existing in the die forging process of high-temperature alloy die forgings, the purpose of the present invention is to provide...
