This utility model discloses a container pallet for loading large insulation panels, belonging to the field of large insulation panel transfer technology. The pallet mainly includes a ladder-shaped pallet bottom support and two oppositely arranged movable pallet bodies. Two adjustable supports with multiple adjustment holes are arranged parallel to each other on the longitudinal beam of the pallet bottom support. The pallet bodies span across the adjustable supports. By connecting the connectors with the adjustment holes, the distance between the two pallet bodies can be adjusted to accommodate insulation panels of different sizes. The pallet body includes a sliding bottom beam, a pallet back plate, side tie rods, a top side limiting plate, and an adjustable partition plate, which together form a stable locking structure. The pallet bottom support is also equipped with special non-standard corner fittings to facilitate hoisting and connection with container trucks. This utility model solves the problems of low transfer efficiency, easy damage, and ultra-wide transportation of large insulation panels, and realizes seamless and efficient docking from production to transportation.

This invention discloses a SPA-H container panel with inclusion defects and its production method. Its chemical composition and weight percentage are as follows: C: 0.060%–0.100%, Si: 0.26–0.35%, Mn: 0.40–0.49%, P: 0.080–0.095%, S≤0.010%, Cu: 0.25–0.31%, Cr: 0.30–0.37%, Ni: 0.060–0.075%, Ti: 0.010–0.035%, Als: 0.015–0.035%, N≤0.0055%, with the balance being Fe and unavoidable impurities. The production method includes slab heating, rough rolling, finish rolling, and coiling. This invention effectively suppresses Cr and Cu alloy enrichment and nitride precipitation by optimizing the composition and process matching, reducing the incidence of inclusion defects, and is suitable for large-scale stable production of container panels.
