The HIYIELD project leverages advanced technologies to promote circular economy practices in steel production by increasing scrap utilization and reducing dependence on pig iron from coal-fired blast furnaces. The project encompasses three industrial demonstration cases, each addressing a critical aspect of scrap processing and integration.
In Demo Case 1, industrial-scale trials were...
The recycling of steel as a secondary raw material in low-carbon steelmaking is limited for maintaining sufficiently low content of tramp elements (TEs) in steel products, as TEs contaminate molten steel during the remelting process in the electric arc furnace (EAF). A molten oxide electrolysis (MOE) has been applied for metal production and new refining processes. A recently proposed...
The steel industry, as one of the main contributors to the CO2 emissions worldwide, is called to make efforts to reduce its carbon footprint. The green steel transformation is focussing on Scope 1, mainly by substitution of the Blast furnace, and Scope 2, by usage of only electricity coming from green sources or by substitution of Natural gas by green hydrogen. In regard of Scope 3,...
Steel producers face increasing pressure to cut costs, lower CO₂ emissions, and enhance safety amid evolving economic and production landscapes. This paper highlights recent advances in measurement technology and digitalization that optimize safety, yield, and refractory performance in hot metallurgical vessels. Key innovations include fully automatic repair systems for electric arc furnace...
The European project ALCHIMIA “Data and decentralized Artificial intelligence for a competitive and green European metallurgy industry” (GA No 101070046) gathers academic and industrial partners in the steelmaking sector to optimize steel scrap use in the Electric Arc Furnaces (EAF) and the Ladle Furnace (LF) operation. The project aims to develop a Federated Learning informatic architecture...
The challenges in the field of electric steelmaking have increased in recent years, especially in terms of the rising quality requirements of the steels to be produced.
These challenges have not only grown, but have also significantly changed due to various factors such as sustainability considerations and carbon footprint. Therefore, some processes, e.g. desulphurization will be shift from...
The use of recycled scrap instead of iron ore is a key strategy for the steel industry to reduce carbon emissions and its reliance on critical raw materials. With the growing demand for scrap, it is becoming increasingly important to handle lower-quality steel scrap effectively. Contamination by unwanted tramp elements, such as copper and tin, can pose significant challenges in producing...
