原标题：ArcelorMittal Poland fires hydrogen furnaces, builds new galvanizing line

ArcelorMittal Poland, the Polish arm of global steel giant ArcelorMittal, has announced that it has launched new hydrogen furnaces at the annealing line of its cold rolling mill at its Kraków site, taking a significant step toward sustainable steelmaking.

With a total investment of PLN 52 million ($14.45 million) under a broader PLN 100 million ($27.79 million) modernization plan, these furnaces mark a key milestone in reducing the environmental footprint of steel production. The new hydrogen furnaces are expected to yield multiple operational and environmental benefits such as increased steel purity and quality by optimized annealing, 50 percent reduced annealing time, increased productivity, lower energy consumption, and the elimination of ammonia.

Alongside the furnace project, ArcelorMittal Poland is constructing a new galvanizing line at the Kraków site. This development aims to reduce zinc consumption and enhance product durability and corrosion resistance.

全球钢铁巨头安赛乐米塔尔波兰分公司安赛乐米塔尔波兰公司宣布，该公司已在克拉科夫工厂的冷轧厂退火线上推出了新的氢气炉，向可持续炼钢迈出了重要一步。

根据更广泛的 1 亿兹罗提（2779 万美元）现代化计划，这些熔炉的总投资为 5200 万兹罗（1445 万美元），标志着减少钢铁生产对环境影响的一个重要里程碑。新型氢气炉有望产生多种运营和环境效益，例如通过优化退火提高钢材纯度和质量、减少 50% 的退火时间、提高生产率、降低能耗和消除氨。

除了熔炉项目外，安赛乐米塔尔波兰公司还在克拉科夫工厂建造一条新的镀锌线。这项开发旨在减少锌的消耗，提高产品的耐用性和耐腐蚀性。
