AI Technical Summary

Benefits of technology

This new technology allows creation of very expensive metal rings made up entirely or partially by casting them into specific shapes without requiring complex processes like cutting off unnecessary material. It also enables direct use during production due to its reduced size compared to traditional methods such as millings or welded seams. Additionally, this technique helps save on labor costs while maintaining long lifespan.

Problems solved by technology

The technical problem addressed by this patented technology relates to producing rings from specific types of alloys called Superalloys which have unique shapes without requiring expensive tools or processes such as milling or drilling.

Embodiment Construction

[0016] To implement the billet making method of the high-temperature alloy large-scale special-shaped cross-section ring blank described in the present invention, it is necessary to provide a forging heating furnace, a forging press, a rolling machine, a bulging die and a high-temperature alloy rod.

[0017] Fig. 1 shows the billet making process flow of superalloy large rectangular cross-section ring billet, and Fig. 2 shows the billet making process flow of using the rectangular cross-section ring billet shown in Fig. 1 to make the special-shaped cross-section ring billet according to the present invention. The process flow shown in Fig. 1 and Fig. 2 completely expresses the billet making method of the superalloy large-scale special-shaped cross-section ring billet of the present invention, and its operation steps are as follows:

[0018] Step 1: Upsetting. The high-temperature alloy bar 1 blanked according to the forging specification is heated to the deformation temperatur...

Abstract

The process of making large irregular ring blank of high temperature alloy includes the steps of heating the high temperature alloy rod to deformation temperature and upsetting into solid cake blank, punching the central hole to obtain hollow cake blank, heating the hollow cake blank to deformation temperature and rolling into ring blank with rectangular cross section, heating the ring blank to deformation temperature and setting in to outer expanding mold and on bottom mold plate, applying pressure to extrude the cake blank with the outer expanding mold and the inner expanding mold for deforming to fill the mold cavity, and demolding to obtain the irregular ring blank. The process of the present invention is used mainly for making ring blank of hard-to-deform alloy and with irregular cross section.
