也是从那时起，中色科技开启了"对标国际先进+深挖客户痛点+自主核心攻坚"之路。他们紧盯全球技 术前沿，积极与国际一流同行开展交流合作，并将研发的根扎进生产一线。 可乐、啤酒、凉茶……生活中，易拉罐几乎随处可见。然而，鲜为人知的是，易拉罐料加工曾是铝加工 行业的"老大难"——我国制造易拉罐的关键材料加工设备，多年来几乎完全依赖进口。 近期，入选"洛阳市装备制造业十大标志性高端装备"的好消息传到了中色科技股份有限公司（以下简 称"中色科技"）。他们研发的2300毫米单机架六辊铝带冷轧机组，结束了国外公司在超薄罐料板带箔关 键装备及轧制工艺技术上的长期垄断，成为打破易拉罐料设备依赖进口局面的"争气机"。 缩小代级差距 小小易拉罐，其材料究竟藏着什么玄机？首先，它超薄，厚度仅相当于两张白纸；其次，它强韧，能够 承受饮料内压、运输堆叠及高速灌装冲击等多种压力；再者，它平整，每生产1000米长的产品，起伏度 要小于1毫米。 六辊轧机是生产易拉罐料的关键设备，还可以生产多种高附加值的铝合金。然而长期以来，六辊轧机完 全依赖进口，成为铝轧机设计行业的"心头之痛"。20年前，有几家铝加工龙头企业花重金从国外引进最 先进的六辊冷 ...

Core Viewpoint - The successful factory acceptance of the first domestically produced 450,000 tons/year polypropylene blending extrusion granulation unit by Dalian Heavy Industry marks a significant advancement in China's equipment manufacturing capabilities, particularly in the petrochemical sector [1][2]. Group 1: Equipment and Technology - The 450,000 tons/year polypropylene blending extrusion granulation unit has passed all performance tests and meets design requirements, showcasing its advanced layout and quality [1]. - The unit's standard load capacity is 56.5 tons/hour, with a maximum load capacity of 67.5 tons/hour, placing its overall performance among the international advanced ranks [2]. - The project team overcame multiple technical challenges over 14 months, achieving autonomy in key technologies such as high-torque transmission stability and high-temperature, high-pressure melt precision blending [2]. Group 2: Strategic Importance - The Tarim 1.2 million tons/year ethylene project is a demonstration of China National Petroleum's commitment to green low-carbon development and high-value resource utilization [1]. - The successful acceptance of this unit signifies a historic breakthrough in the design, manufacturing, and integration of large-scale blending extrusion granulation equipment in China, transitioning from a "follower" to a "runner" in the industry [2]. - The project supports the national strategy for major equipment autonomy and domestic production, providing a foundation for future large-scale ethylene and polypropylene project construction [2].
