Abstract

The invention discloses a method for manufacturing a GH5188 square exhaust nozzle for an aero-engine, including blanking, heating, thickening, punching, rolling, etc., wherein: the ring billet obtained by rolling is extruded into billet, and the final shape of the tail nozzle is carried out by using a horse frame and a square horse bar. Beneficial effects of the present invention: Since the billet is bent after rolling, the wall thickness is uniform and the material distribution is accurate, which ensures the uniform wall thickness of the forging after forming and improves the utilization rate of raw materials; since the billet is made by rolling, forming At the same time, the horse frame and square horse bar are used, and the rolling and forming process are optimized, so that the forging has uniform structure, stable mechanical properties, and prolongs the service life.

Description

technical field [0001] The invention relates to a method for manufacturing a GH5188 square exhaust nozzle for an aero-engine. Background technique [0002] GH5188 is a solid-solution-strengthened cobalt-based superalloy. Adding tungsten for solid-solution strengthening makes the alloy have excellent high-temperature thermal strength. Adding a high content of chromium and trace element lanthanum makes the alloy have good high-temperature oxidation resistance and satisfactory Excellent molding, welding and other process performance, suitable for making parts on aero-engines that require high strength below 980°C and anti-oxidation below 1100°C, and can also be used on aerospace engines and space shuttles. The alloy is widely used in foreign countries to make high-temperature components of gas turbines and missiles, such as combustion chambers, exhaust nozzles, and heat exchangers in the nuclear energy industry. High-temperature components such as blades have passed the long-t...
