Problems solved by technology

At present, once such high-temperature alloy products are used, they cannot be recycled and reproduced into original products for recycling, but are used as waste materials for depreciation. This not only wastes resources, but also has a high cost of using high-temperature alloy products.

Embodiment 2

[0023] Such as figure 1 , image 3 As shown, the difference between this example and Example 1 is that the granulation in this example adopts the pre-alloying atomization method for granulation, that is, pre-alloying is remelted first, and then atomization is used to make powder. The ultra-fine powder can be produced by circulating swirling ball milling process, that is, the coarse powder is first sieved by 80#, then separated by 180# ball mill hydrocyclone, and then separated by 325# ball mill hydrocyclone to obtain 10 microns The powder is then centrifugally concentrated, dried and pulverized to obtain superfine powder, and the particle size of the superfine powder is less than or equal to 10 microns. The invention adopts the mixed liquid of oil and alcohol as the hydraulic medium of the circulating swirl ball milling production process, which can not only reduce the oxidation degree of superfine superalloy powder, but also promote the separation effect of the circulating s...

Abstract

The invention is related to a method to reuse a superalloy ware in a cycle. It includes the steps of: The recycle superalloy is milled to very small particles and powder, then activate it use reduction method, then the superalloy is regenerated. The invention mills the waste superalloy is ware to small particles, and powder the particles, and make the size of powder below superfine powder. So it can improve such performances as transformation, strain relaxation, mechanical fatigue and thermal fatigue of the superalloy wares. The surface activation handling using reduction method can decrease the oxygen index of the recycle powder, and reduce various factors that baffle the sintering. It improves the sinter performances of the regenerated superalloy wares. The invention reduces and activates the recycle powder which is produced use hydrogen reduction in the condition of high temperature. The reduction and activation can eliminate the gas, oxide film and volatile production of chemical reaction that adsorbed in the surface of particles.

Description

technical field [0001] The invention relates to a method for regenerating and recycling materials of high-temperature alloy products. Background technique [0002] High temperature oxidation refers to the metal in a high temperature oxidizing atmosphere (O 2 , S, halogen and water vapor, etc.) are corroded. Generally, industrial superalloys work in various oxidation and corrosion environments. Without sufficient oxidation resistance, they will soon be oxidized and corroded and fail. Therefore, for high-temperature materials, oxidation resistance and mechanical properties are equally important. , tungsten, molybdenum, niobium, tantalum and other refractory metals have extremely high melting point and high temperature strength, but because of their poor high temperature oxidation resistance, they cannot form a protective high temperature oxidation resistance film, so they are rarely used alone in large quantities for high temperature Structural materials, but applied in the ...
