奥钢联多纳维茨电弧炉安装基本完成 冷调试启动 2027年上半年产首炉钢
奥地利钢铁集团奥钢联（voestalpine）宣布，其多纳维茨（Donawitz）钢厂新建电弧炉的安装工作已按计划基本完成，部分区域已开始冷调试，对输送系统、液压系统、电气装置、冷却回路与自动化系统进行测试。新电弧炉由炉体下部、上部与摇架等核心部件及配套基础设施组成。运抵现场的近90万个零部件总重约8,500吨，经船舶、铁路与卡车运达。项目由70多家公司参与，其中约九成为奥地利企业，现场约有500名技术工人；核心部件安装与首次运行由意大利达涅利（Danieli）公司统筹协调。
该电弧炉是奥钢联"greentec steel"（绿色钢铁）计划的一部分，该公司称其为奥地利最大的气候保护计划。奥钢联首席执行官赫伯特·艾本施泰纳表示，该计划在林茨与多纳维茨两地均"在时间和预算上完全按进度推进"。主要建设与安装工作将于2026年内完成；全面投产后，多纳维茨厂每年可生产约85万吨减碳钢。两地的首炉钢计划于2027年上半年在新电弧炉中熔炼。
Voestalpine Completes Electric Arc Furnace Installation at Donawitz, Cold Commissioning Begins
Austrian steel group voestalpine said installation of the new electric arc furnace at its Donawitz site has been largely completed on schedule, and that cold commissioning has begun in some areas, with conveyor systems, hydraulic systems, electrical installations, cooling circuits and automation systems being tested.
The furnace consists of core components such as a lower and upper vessel and a rocker, together with associated infrastructure and utility systems. The nearly 900,000 individual components delivered weigh a total of around 8,500 tons and were transported to the site by ship, train and truck. More than 70 companies are working on the project, some 90% of them Austrian, with around 500 skilled workers currently active on the site; lead partner Danieli is coordinating installation of the furnace's core components and its first operation.
The furnace forms part of voestalpine's greentec steel program, which the company describes as Austria's largest climate protection program. Chief Executive Herbert Eibensteiner said the program in Linz and Donawitz is right on schedule in terms of both time and budget. Major construction and installation work will be completed in 2026; once fully operational, the Donawitz furnace will be able to produce around 850,000 tons of CO2-reduced steel annually. The first melts in the new electric arc furnaces in Donawitz and Linz are planned for the first half of 2027.
