浦项制铁（POSCO）正在扩大其高级汽车钢板的生产能力，以寻求在未来出行市场中强化其地位。
9月8日，POSCO宣布其在光阳工厂的第8条连续镀锌线（8CGL）已破土动工。新设施年产能为45万吨。
8CGL将专门生产用于汽车外板的热镀锌钢板，计划于2028年完工。热镀锌钢板表面镀有锌层，具有强耐腐蚀性和良好的表面光洁度，广泛用于车身面板和家电材料。
随着汽车变得更加高端和精密，对该材料的需求持续上升。汽车制造商越来越需要具有更好涂装性、耐腐蚀性和成型性的外板钢板。
该项目是POSCO九年来首个新热镀锌设施，此前其最近一次投资是在2017年。2015年，公司开始在光阳建设第7条连续镀锌线，该设施年产能50万吨，总投资2554亿韩元。POSCO从订购、工程设计到制造和施工，全程内部处理。
为了满足汽车行业向更大、更高级车辆转变过程中对下一代汽车钢板的需求，POSCO计划在8CGL项目上投资约4800亿韩元。完成后，该投资将使公司的热镀锌钢板总年产能提高到495万吨。
新线预计还将成为低碳汽车钢板的关键生产基地，与新建的电弧炉相连接。POSCO计划安装针对电弧炉生产钢板优化的超高温热处理设备，以帮助满足全球汽车制造商对低碳钢板日益增长的需求。
该设施还将增强POSCO生产用于中型及以上车辆（包括SUV和休闲车）外板的宽幅汽车钢板的能力。
POSCO还计划通过AI提高生产率和质量竞争力。凭借超过30年的运营经验，公司将应用AI技术实时分析材料、工艺和质量数据，并相应控制设备。目标是减少质量波动和缺陷，同时提高制造效率。
公司还计划通过部署AI和机器人执行高风险任务（如去除熔融锌中的杂质或从高温液态锌中取样）来加速制造AI转型。
“通过建设POSCO专业化的汽车钢板生产设施，能够以更强的成本和技术竞争力生产下一代高质量汽车钢板，我们将在日益激烈的全球竞争中进一步巩固POSCO的技术领导地位，”POSCO社长李熙根（Lee Hee-keun）表示。

POSCO is expanding its production capacity for premium automotive steel sheets as it seeks to strengthen its position in the future mobility market.
On Sep. 8, POSCO announced that it had broken ground for its No. 8 Continuous Galvanizing Line (8CGL) at the Gwangyang Works. The new facility will have an annual production capacity of 450,000 metric tons.
The 8CGL will specialize in producing hot-dip galvanized steel sheets for automotive exterior panels and is scheduled for completion in 2028. Hot-dip galvanized steel is coated with zinc, giving it strong corrosion resistance and an attractive surface finish. It is widely used for vehicle body panels and home-appliance materials.
Demand for the material has continued to rise as vehicles become more premium and sophisticated. Automakers increasingly require exterior-panel steel with improved paintability, corrosion resistance, and formability.
The project marks POSCO's first new hot-dip galvanizing facility in nine years, following its previous investment in 2017. In 2015, the company began construction of its No. 7 Continuous Galvanizing Line at Gwangyang, a 500,000-ton-per-year facility built with a total investment of 255.4 billion KRW. POSCO handled the entire process internally, from ordering and engineering design to fabrication and construction.
To meet demand for next-generation automotive steel amid the industry's shift toward larger, more premium vehicles, POSCO plans to invest about 480 billion KRW in the 8CGL project. Once completed, the investment will raise the company's total annual capacity for hot-dip galvanized steel to 4.95 million metric tons.
The new line is also expected to become a key production hub for lower-carbon automotive steel, in connection with a newly built electric arc furnace. POSCO plans to install ultra-high-temperature heat-treatment equipment optimized for electric-arc-furnace-produced steel sheets, helping meet global automakers' growing demand for lower-carbon steel.
The facility will also strengthen POSCO's capacity to produce wide automotive steel sheets for exterior panels used on mid-size and larger vehicles, including SUVs and recreational vehicles.
POSCO also plans to improve productivity and quality competitiveness through AI. Drawing on more than 30 years of operational expertise, the company will apply AI technologies to analyze material, process, and quality data in real time and control equipment accordingly. The goal is to reduce quality variation and defects while improving manufacturing efficiency.
The company also plans to accelerate manufacturing AI transformation by deploying AI and robots for high-risk tasks, such as removing impurities from molten zinc or collecting samples from high-temperature liquid zinc.
“By building POSCO's specialized automotive steel production facilities, capable of producing next-generation, high-quality automotive steel with stronger cost and technology competitiveness, we will further reinforce POSCO's technology leadership amid intensifying global competition,” POSCO President Lee Hee-keun said.
