In early December 2025, a key milestone was reached in the project of 1380mm six-roll reversible cold rolling mill of Shandong Luzha New Material Co., Ltd. - the frame, as the "skeleton" and core bearing structure of the rolling mill, was successfully hoisted into place. The successful completion of this key node not only laid a solid foundation for the subsequent equipment installation, but also marked a major breakthrough in the construction of the project.
