Abstract

The present invention provides a method for processing returned materials of chip-like superalloys. The method is carried out in accordance with the following steps: step S1, sorting; step S2, crushing; step S3, alkali cleaning; step S4, cleaning with a booster solution; step S5, pickling; step S6, water washing; step S7, drying. The embodiment of the present invention can effectively remove the non-metallic inclusions on the surface of the chip-like superalloy return material, reduce the scum content of the superalloy return material, and melt the treated superalloy return material. The master alloy inclusion content after smelting is 0.5 , the scum content is within 2%; and it can effectively remove the oil stain on the surface of the scrap superalloy return material, and the residual carbon content range is within 100ppm. After the superalloy return material treated by this treatment method is smelted, its master alloy basically reaches The new material level greatly improves the utilization rate of returned materials.

Description

A kind of crumb superalloy return material processing method technical field The invention belongs to the crumb-shaped return material processing technical field, relate in particular to a kind of crumb-shaped superalloy return material processing method Law. Background technique [0002] Superalloys are those that can withstand a certain stress and have anti-oxidation or anti-corrosion properties at a high temperature of 600-1200 °C. Alloy is the material of hot end components such as aviation and aerospace engines and ground gas turbines in my country, especially turbine blades and guide vanes. The material used for parts such as blades and turbine disks. In recent years, with the rapid development of aero-engine and gas turbine industries, high temperature The use of alloys has been greatly increased, and raw materials such as nickel (Ni), chromium (Cr), cobalt (Co), tungsten (W), molybdenum (Mo), and rhenium (Re) have been largely eliminated. consumption. There...
