| description | The invention relates to a method for refining carbonitride in GH4169 alloy by controlling the addition amount of return scraps, and belongs to the technical field of reutilization of high-temperature alloy return scraps. Comprising the following steps: selecting a GH4169 brand-new refined pure material and a return scrap as raw materials for preparing an alloy; the addition amount of the return scrap in the raw materials is 10-50wt%; the content of carbon and nitrogen in the return scrap comprises the following components in percentage by mass: 0.02-0.08% of C and less than or equal to 0.003% of N; the raw materials are sequentially subjected to vacuum induction melting, electroslag remelting and vacuum arc remelting to obtain a VAR consumable ingot; homogenization treatment: first-stage homogenization treatment, second-stage homogenization treatment and third-stage homogenization treatment are included, and the total heat preservation time at the temperature of 1180 DEG C or above exceeds 72 hours; cogging |
