Embodiment Construction

[0018] Take GH4169 as an example

[0019] like figure 1 As shown, in the present invention, a method for recycling and processing superalloy scraps of the present embodiment, step 1) is to carry out sorting inspection of alloy scraps; there are many domestically used superalloy grades, and dozens of them are often used. The sources of recycled materials purchased are complex, and parts production and processing manufacturers generally do not accurately classify and collect waste materials. Therefore, it is very important to quickly and accurately identify the recovered waste materials; the identification technology is spectral identification, A special metal alloy material composition analyzer imported from abroad is adopted, and various common domestic and foreign metal material composition data inventories are introduced into the analyzer. The database covers all domestic metal materials, including steel, aluminum-magnesium alloy, superalloy, titanium There are about 859 ki...

Abstract

The invention provides a treatment method of a high-temperature alloy vacuum-grade scrap return material. The treatment method comprises the following steps of 1) carrying out sorting on an alloy scrap material; 2) and carrying out cutting type crushing on the alloy scrap material; 3) cleaning the alloy scrap material; 4) drying the alloy scrap material; and 5) carrying out block pressing on the alloy scrap material. According to the high-temperature alloy vacuum-grade scrap return material, oil stains and impurities on the scrap material can be removed, so that a high-temperature alloy whichcan be directly used for smelting by using a vacuum furnace can be obtained, namely a scrap material recovery block with relatively high purity is obtained, the scrap material can be recycled, and resources are greatly saved.

Description

technical field [0001] The invention relates to a method for processing returned materials, in particular to a method for recycling and processing superalloy vacuum grade scraps. Background technique [0002] Superalloys are based on iron (Fe), nickel (Ni), and cobalt (Co), adding tungsten (W), molybdenum (Mo), tantalum (Ta), rhenium (Re), hafnium (Hf), aluminum (Al) ), titanium (Ti), niobium (Nb) and other elements with high bearing temperature of special alloys, usually high temperature alloys can withstand a certain stress at 600-1200 ℃ high temperature and have anti-oxidation or anti-corrosion ability, according to the main elements of the matrix It can be divided into iron-based superalloy, nickel-based superalloy and cobalt-based superalloy. According to the preparation process, it can be divided into deformed superalloy, cast superalloy and powder metallurgy superalloy. According to the strengthening methods, there are solid solution strengthening type, precipitatio...
