This invention discloses a radial forging method for Ni30 alloy ultra-long products, relating to the field of metal forging technology. The radial forging steps are as follows: S1: First, heat the intermediate billet to a holding temperature. After holding for T1 time, remove the intermediate billet; S2: Cover both ends of the intermediate billet with insulating material, then place the intermediate billet back into the furnace for a second holding time (T2 time). After the second holding time, the insulating material forms an insulating layer at both ends of the intermediate billet. The thermal conductivity of the insulating layer is lower than that of the intermediate billet, thus obtaining the billet to be forged; S3: Clamp the insulating layer at both ends of the billet to be forged using the jaws of a radial forging machine, and then perform open forging to obtain the finished ultra-long billet. This invention, by using a soft-wrapping technology at both ends of the intermediate billet, avoids direct contact between the jaws of the radial forging machine and the intermediate billet, reducing the heat transfer rate and allowing the temperature at both ends of the billet to be maintained above 900℃ for a longer period, achieving continuous deformation without cracking.

This invention discloses a method and system for preventing oxidation of recycled copper rods, relating to the field of non-ferrous metal surface protection. The method includes material preparation, pretreatment, preparation of an anti-oxidation solution, dip coating, drying and curing, and packaging. This invention offers excellent anti-oxidation performance: the anti-oxidation film is dense and uniform, effectively isolating oxygen and moisture from contact with the copper surface. Recycled copper rods stored in a natural environment show no significant oxidation after more than 6 months, with an anti-oxidation efficiency ≥98%, far superior to traditional methods. The film exhibits strong adhesion: the silane coupling agent forms a chemical bond with the copper surface, and combined with the curing treatment, the film adhesion is ≥5N / cm, making it difficult to peel off and able to withstand minor friction during storage and transportation.
