On the path toward low-carbon steelmaking and increased circularity, the Electric Arc Furnace (EAF) will be pivotal for European steelmakers. Within the EU-funded Horizon Europe project “Demonstration of Digital twins for a Green Steel value chain (DiGreeS)” an integrated digitalisation approach is being developed across the steel value chain to leverage process data and human experience for...
Accurate prediction of thermodynamic behavior in metallurgical melting processes is essential for optimizing industrial operations and reducing experimental costs. This work introduces a computational tool that integrates the Process Metallurgy module of Thermo-Calc with MATLAB to enable automated, scalable evaluations of multiple process scenarios. Traditionally, performing sequential...
Abstract
This work introduces an innovative method for controlling the stability of direct current (DC) arcs in reducing argon-hydrogen atmospheres, a key enabler for hydrogen-plasma smelting reduction (HPSR) processes aimed at decarbonizing steelmaking. By dynamically adjusting current, the system maintains robust arc behaviour under challenging conditions, supporting both process...
This presentation introduces a scrap-aware adaptive electrode and process control concept for Electric Arc Furnaces (EAFs). The system performs an in-situ scrap classification based on process-integrated signals to identify scrap stratification, density distribution and expected melting behavior. These indicators drive an adaptive control layer that continuously adjusts transformer tap...
The steel manufacturing industry faces increasingly demanding technological challenges, particularly regarding the safety, efficiency, and reliability of maintenance processes. One of the most critical issues is monitoring the condition of refractory linings in furnaces, ladles, and converters without exposing operators to risk or interrupting production. In response to this need,...
It’s not a question anymore, it’s already a fact that the transition towards CO2 reduced steelmaking will come along with a great number of changes in numerous areas of the production chain. Focusing on the melt section, one of the biggest challenges is the entry of new/different equipment to process from scrap to casting. To cope with these, it is mandatory to use state-of-the-art technology...
