这套装备实现了中国人的“易拉罐自由”——2300毫米六辊铝带冷轧机组研发记

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]. - For over two decades, the industry faced challenges due to reliance on imported six-roll mills, which limited domestic production capabilities [2][3]. - The first domestic 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 foreign monopolies in this technology [5][6]. - The new mill design significantly reduces costs by two-thirds compared to imported equipment and shortens the construction 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 company is focusing on addressing industry pain points and aims to develop a "4.0+1" version of the six-roll mill, integrating advanced technologies such as 5G and artificial intelligence [7][8]. - The introduction of electromagnetic induction heating technology has improved efficiency and safety in the production process, replacing traditional heating methods [7]. - The company plans to concentrate resources on developing major technological equipment, emphasizing high-end equipment for the aluminum and copper materials industry [8].
