SynopsisVoestalpine Stahl Donawitz in Austria has chosen Danieli to supply two new Digimelters for its special steel production, replacing blast furnace #4. These Danieli Digimelters, equipped with Q-One power feeders, aim to produce up to 107 metric tons per hour of high-quality green steel, with an initial capacity of up to 1 million tons per year. The Q-One technology enables dynamic electronic control of the arc, reduces power consumption, and allows the use of renewable energy sources. Voestalpine plans to increase electric steelmaking capability to 1.7 million tons per year, enhancing process control and emissions reduction.Articlevoestalpine Stahl Donawitz GmbH, a leading player in the steel industry, has taken a significant step towards reducing carbon emissions and producing ultra-high-quality green steel. The Austrian company has awarded a pivotal contract to Danieli, a renowned leader in steel technology solutions.The heart of this transformation lies in the adoption of two cutting-edge Danieli Digimelters at its special steel production facility in Leoben, Austria. These advanced Digimelters are set to replace the traditional blast furnace #4, heralding a new era in steel production.What sets these Digimelters apart is their integration with the Q-One power feeders, a patented technology by Danieli. This groundbreaking addition allows for precise, dynamic electronic control of the arc, all while having minimal impact on the power grid. Such control is instrumental in achieving consistent, high-quality green steel.One of the key advantages of the Q-One power feeder is its compatibility with renewable energy sources generated on-site. This hybrid design aligns perfectly with the push towards sustainable steel production.Initially configured with four modules, each providing 67 MVA per Digimelter, the system has the flexibility for expansion. voestalpine Stahl Donawitz GmbH has the option to add two more modules, paving the way to increase electric steelmaking capacity to a remarkable 1.7 million metric tons per year.Managing the melting process will be Danieli Q-Melt, an adaptive process control system that handles both electrical and chemical profiles. This dynamic control significantly reduces process variability, enhancing furnace utilization and efficiency.As a part of this comprehensive upgrade, Danieli will also implement a fume-treatment plant and heat-recovery system. These additions will contribute to further reductions in direct and indirect emissions.The expected timeline for this transformative project is ambitious yet achievable. The new electric arc furnace plant is anticipated to begin operations at the outset of 2027.Conclusionvoestalpine Stahl Donawitz's decision to adopt Danieli's advanced Digimelters and Q-One power feeders marks a crucial transition in the steel industry. By prioritizing green steel production and embracing cutting-edge technology, the company is not only set to reduce carbon emissions but also enhance the quality and efficiency of its steel production processes. This move underscores the industry's commitment to sustainability and innovation in the pursuit of a greener future.
