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 belongs to the field of biomedical technology, specifically disclosing an injectable embolic agent, its preparation method, and its application. The embolic agent is a hydrocolloid system containing core-shell structured nanoparticles: the core contains Cu... 2+ Salt and ATOX1 inhibitors, where ATOX1 inhibitors can inhibit copper ion efflux and promote intracellular copper accumulation, and interact with Cu 2+ It synergistically induces copper death in tumor cells; the shell is a thermosensitive block copolymer hydrogel that can interact with Cu. 2+ Coordination bonds are formed, enhancing the stability of nanoparticles, while a sol-gel transition occurs at physiological temperatures, enabling precise vascular embolization; the overall core-shell structure allows for the formation of Cu... 2+ The sustained-release effect of ATOX1 inhibitors was observed. In the VX2 rabbit hepatocellular carcinoma model, this embolization agent significantly improved tumor necrosis rate and reduced metastasis rate compared to traditional iodized oil embolization; it also downregulated hypoxia- and angiogenesis-related factors such as HIF-1α, VEGF, and CD31, inhibited MMP9-mediated tumor invasion and metastasis, and promoted CD8+. + T-cell infiltration effectively improves the tumor immunosuppressive microenvironment after transarterial chemoembolization.
