The invention belongs to the technical field of additive manufacturing, and relates to a mold steel spherical powder for additive manufacturing and a recycling method thereof. Combined with plasma rotating electrode powder making, it is proposed to first hot-isostatically press the powder into an ingot, and then process it into an electrode rod. After milling, the fine-grained powder can be used for additive manufacturing, and the coarse-grained powder is powdered by hot isostatic pressing, forging, machining, and plasma rotating electrode, and the recycling of the coarse-grained die steel powder is completed. . The recycling method can solve the problem of a large amount of backlog of mold steel powder with coarse particle size, and the problem of high cost of fine particle powder due to unavailability of some powders, and can also overcome the problem of burning of metal elements in powder reuse. , and the problem of increased gas elements in powder reuse. |
