日经报道：日本制铁拟向宾州蒙谷钢铁厂投资约30亿美元升级热轧设备，新设备2029年下半年投产
据《日经新闻》周四报道，日本制铁计划向美国钢铁公司运营的宾夕法尼亚州蒙谷钢铁厂 （Mon Valley Works）投资约30亿美元，升级其热轧生产设备。路透社引述该报道称，日本制铁暂未回应置评请求。
这笔投资是日本制铁2025年收购美国钢铁公司后承诺的"2028年前向美钢投资110亿美元"计划的一部分。据报道，蒙谷厂的热轧设备已运行约90年——该设备将高炉铁水铸成的板坯加热并轧制成更薄的钢材；新设备预计2029年下半年投产，可生产更高质量的钢材。
日本制铁8月曾上调2026 财年盈利预期，得益于美国钢铁业务盈利增强和钢铁市场走强。蒙谷厂位于匹兹堡以南，是美国钢铁在宾州的核心生产基地，此次升级被视为日铁兑现对美投资承诺、巩固其在美国高端钢材市场地位的关键一步。不过报道尚未披露具体的设备供应商与施工时间表，投资细节仍有待日铁官方确认。
Nikkei: Nippon Steel to Invest About $3 Billion Upgrading Hot Rolling Equipment at Pennsylvania's Mon Valley Works; New Equipment Online in Second Half of 2029
According to a Nikkei report on Thursday, Nippon Steel plans to invest about $3 billion in U.S. Steel's Mon Valley Works in Pennsylvania to upgrade its hot rolling equipment. Reuters, citing the report, said Nippon Steel had not responded to a request for comment.
The investment is part of Nippon Steel's commitment, made after acquiring U.S. Steel in 2025, to invest $11 billion in the company by 2028. The Mon Valley plant's hot rolling equipment has reportedly been in operation for about 90 years — it reheats slabs cast from blast furnace iron and rolls them into thinner steel; the new equipment, expected to come online in the second half of 2029, will be able to produce higher-quality steel.
Nippon Steel raised its fiscal 2026 earnings forecast in August on stronger earnings from its U.S. Steel business and a firmer steel market. Mon Valley Works, south of Pittsburgh, is U.S. Steel's core production base in Pennsylvania, and the upgrade is seen as a key step in Nippon Steel honoring its U.S. investment pledge and consolidating its position in the American high-end steel market. However, the report did not disclose specific equipment suppliers or a construction timetable, and details await official confirmation from Nippon Steel.
