这套装备实现了中国人的“易拉罐自由”

Core Viewpoint - The development of a domestically produced 2300mm single-stand six-roll aluminum cold rolling mill by China Nonferrous Metal Industry's Foreign Engineering and Construction Co., Ltd. (中色科技) has ended the long-standing reliance on imported equipment for producing aluminum can materials, marking a significant breakthrough in the industry [1][5]. Group 1: Equipment Development - The six-roll mill is crucial for producing ultra-thin aluminum can materials, which have specific requirements for thickness, strength, and flatness [2][5]. - Historically, the six-roll mill technology was entirely dependent on imports, creating a gap in the aluminum processing industry [2][4]. - The first domestically produced UCM six-roll mill was developed in 2004, but it was considered rudimentary compared to international standards [3][4]. Group 2: Technological Advancements - The latest 4.0 version of the six-roll mill successfully produced aluminum strips thinner than 0.258mm, achieving stable mass production and breaking the foreign monopoly on this technology [5][6]. - The new equipment significantly reduces costs by two-thirds compared to imported machines and shortens the design and manufacturing cycle [6]. - The mill features an advanced UCM system that allows for precise control of the rolling process, enhancing the quality of the produced materials [6][7]. Group 3: Innovation and Future Directions - The introduction of electromagnetic induction heating technology has improved the efficiency and safety of the rolling process, replacing traditional heating methods [7]. - The company aims to continue advancing its technology by integrating 5G and artificial intelligence into its operations [8]. - Future plans include focusing on high-end equipment development to strengthen the domestic aluminum and copper material industry [8].
