To achieve a carbon-neutral EAF system for high-quality sheet production, rapid scrap melting is essential for efficient DRI/HBI dissolution.
This study presents an integrated oxygen lance-burner design to enhance thermal efficiency and melting kinetics.
Experimental validation and numerical simulations were conducted to assess performance and optimize key parameters, with findings and...
The path to reducing steel's CO₂ footprint is increasingly clear, with the industry shifting toward electric arc furnace (EAF) steelmaking. This transition relies on recycled scrap and partially substitutes virgin materials with direct reduced iron (DRI) or hot briquetted iron (HBI). However, the changing quality of input materials, particularly the reduced purity of raw materials and...
The steel industry, responsible for 7% of global CO₂ emissions, significantly contributes to environmental pollution and intensive water consumption. Decarbonizing the sector requires adopting innovative technologies such as hydrogen-based direct reduction, recycling in electric arc furnaces (EAF), and iron ore electrolysis. However, this transition presents major challenges, including the...
The iron and steel industry contributes significantly to global greenhouse gas emissions, accounting for 7.2% of the total. The predominant BF-BOF ironmaking route, responsible for 70% of global pig iron production, is primarily coal-based, posing substantial challenges for decarbonization. As steel industry stakeholders strive to reduce carbon footprints while maintaining economic viability,...
The transition to carbon-free steel production presents significant challenges for the industry. Adapting to new processes, production routes, and logistics is a central aspect of this transformation. Particularly notable is the shift from traditional Blast Furnace (BF) / Basic Oxygen Furnace (BOF) route to electric steelmaking route. This change requires not only a comprehensive restructuring...
Life Cycle Assessment (LCA) is the most widely used methodology to quantify the potential environmental impact of the steelmaking industry, but it can been used to support the investigation of decarbonization strategies in the steel sector.
In this contribution we aim to illustrate how LCA can be used to support the decision-making process within the context of GreenHeatEAF “Gradual...
As part of the decarbonization process in the steelmaking industry, the direct reduction of iron ores, the use of green hydrogen as an energy source and/or the application of carbon capture technologies are crucial for achieving carbon neutrality. The study will underscore the importance of laboratory material testing and process simulation tools in determining the optimal and most feasible...
Decarbonization of the steel industry has multiplied the number of projects involving construction of a direct reduction plant.
Shorter project schedules and avoiding cost/availability issues with onsite construction skilled workers are key advantages of a modularized construction strategy.
TECNICAS REUNIDAS has executed projects in other industrial areas using this strategy and has...
