Abstract

The invention provides a treatment method for scrap-shaped high-temperature alloy return scraps. The treatment method comprises the following steps of S1, sorting; S2, crushing; S3, alkali washing; S4, washing with a washing assisting solution; S5, acid pickling; S6, washing with water; and S7, drying. According to the treatment method in the embodiment, non-metallic inclusions on the surfaces of the scrap-shaped high-temperature alloy return scraps can be effectively removed, the scum content of the high-temperature alloy return scraps is reduced, the treated high-temperature alloy return scraps are smelted, the inclusion content of a smelted mother alloy is 0.5 level, and the scum content is within 2%; and oil stains on the surfaces of the scrap-shaped high-temperature alloy return scraps can be effectively removed, the residual carbon content range is within 100 ppm, after the high-temperature alloy return scraps treated through the treatment method are smelted, the mother alloy basically reaches the brand new material level, and the utilization rate of the return scraps is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of chip-like return materials processing, and in particular relates to a method for processing chip-like superalloy return materials. Background technique [0002] Superalloys are alloys that can withstand a certain stress at a high temperature of 600-1200 ° C and have anti-oxidation or corrosion resistance. They are materials for hot-end components such as my country's aviation, aerospace engines, and ground gas turbines, especially turbine blades, guide vanes, and turbine disks. Materials used for other parts. In recent years, with the rapid development of the aero-engine and gas turbine industries, the use of superalloys has greatly increased, nickel (Ni), chromium (Cr), cobalt (Co), tungsten (W), molybdenum (Mo), rhenium (Re) and other raw materials are consumed in large quantities. Therefore, from the perspective of resource recycling, it is very necessary to carry out the recycling and reuse of supera...
