CHALCO(SH:601600) Zhong Guo Chan Ye Jing Ji Xin Xi Wang·2025-10-21 21:54Core Viewpoint - The successful development of the 2300mm single-stand six-roll cold rolling mill by China Aluminum Corporation's subsidiary, China Nonferrous Metal Technology Co., Ltd. (中色科技), has broken the long-standing foreign monopoly on key equipment and rolling process technology for ultra-thin can materials, marking a significant advancement in the domestic aluminum processing industry [1][2]. Group 1: Technological Breakthrough - The new 4.0 version of the six-roll mill successfully produced qualified aluminum materials in June 2023 and is expected to pass final acceptance in September 2024 [2]. - The mill features a self-developed UCM (Universal Crown Control) system that allows for a lateral movement of ±550mm, enabling the stable mass production of aluminum strips for can bodies thinner than 0.258mm [2]. Group 2: Economic Impact - The cost of imported six-roll cold rolling mills exceeds 300 million yuan, with long construction cycles; the new domestic equipment significantly reduces costs and shortens design and manufacturing timelines [2]. Group 3: Future Innovations - China Nonferrous Metal Technology Co., Ltd. is pursuing further innovations with the "4.0+1" version, exploring areas such as full 3D drawings and the integration of 5G and artificial intelligence [2]. - The company aims to enhance the development of high-end equipment in areas like continuous rolling, wide-width, high-speed, high-precision, and intelligent manufacturing to contribute to the high-quality development of the domestic aluminum and copper-based materials industry [2].
