美钢批准约30亿美元 蒙谷工厂新建热轧带钢厂
美国钢铁公司2026年10月22日表示,董事会已批准约30亿美元,在蒙谷工厂新建一座热轧带钢厂。年产能将从约220万吨提高到约350万吨。

蒙谷项目
美国钢铁公司表示,新厂将取代西米夫林欧文厂一座已有87年历史的热轧带钢厂。这是日本制铁到2028年总额110亿美元美国计划中最大的单项投资。新厂建在布拉多克的埃德加·汤姆森厂,该厂与克莱顿焦化厂、欧文厂同属蒙谷工厂。
据PublicSource报道,30亿美元高于此前承诺的至多25亿美元,而最初的投资承诺为10亿美元。彭博社报道称,投资额上调是因为成本上升。
日本制铁表示,新设备包括步进梁式加热炉和定径压力机,用来提高生产率、降低能耗、改善材料收得率。据PublicSource报道,公司向社区领袖提供的材料显示,新厂将让蒙谷工厂生产面向汽车客户的高强度钢。这类产品该厂目前无法以有竞争力的方式生产。
公司表示,年产能将从约220万吨增至约350万吨,增幅约60%。产品面向汽车、家电和能源客户。施工将在取得许可后开始,首批生产目标定在2029年下半年,距投资决定约三年。
美国钢铁公司估计,该项目将在蒙谷工厂保住约3000个工作岗位,并在三年内创造近3200个间接和衍生岗位,带来至多17亿美元的经济效益。PublicSource在报道此前至多25亿美元的计划时也提到了这些估算。
日本制铁的美国押注
据路透社报道,日本制铁在经历18个月的政治和监管博弈后,于2025年6月完成对美国钢铁公司149亿美元的收购。蒙谷工厂是这家日本公司到2028年底前向其美国子公司投入110亿美元承诺中最大的单项工程。
美国钢铁公司已成为母公司的增长引擎。据Manufacturing Dive报道,日本制铁将美国钢铁公司2026财年的业务利润预期从1000亿日元上调至1800亿日元(11.4亿美元),理由是高炉重启和美国市场复苏。此次上调是日本制铁提升美国钢铁公司产量、能效、生产率和质量计划的一部分。
据路透社报道,副董事长森高弘6月表示,美国热轧钢板售价超过每吨1200美元,是亚洲水平的两倍多。他还说,美国钢铁公司长期内每年可赚取3000亿至4000亿日元。日本制铁已表示,计划在三到五年内将美国的钢铁产量翻倍。
