Method for processing high-temperature alloy die forging piece with central hole

Abstract

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...

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
