434. Influence of Hydrogen-DRI on the EAF process

Leon Heinl (Primetals Technologies)

Steelmaking - Electric steelmaking

Keynote Presentation

The steelmaking industry, as one of the major emitters of greenhouse gases, is undergoing a transformation towards greener technologies. One of the key players in this transition is the electric arc furnace (EAF), which is fed with scrap and direct reduced iron (DRI), with an increasing proportion of DRI used for high-quality steel grades. Traditionally, DRI production relies on natural gas as...

252. Effects of H2 as energy source and biocarbon injection in EAF

Steelmaking - Electric steelmaking

Oral

The Electric Arc Furnace (EAF) is central for steel industry transformation toward Green Steel production, with ever increasing steel production via the EAF route. However, there are still significant direct fossil CO2 emissions connected to the common EAF operation. Two techniques aimed at reducing direct fossil CO2 emissions from the EAFs are replacing Natural Gas (NG) with H2 as fuel and...

Steelmaking - Electric steelmaking

Oral

In the context of the decarbonization of the steel industry, the electric arc furnace (EAF) has emerged as a primary focus of research. Historically, the EAF has been predominantly utilized in recycling-based steelmaking, specifically for the melting of scrap materials to produce crude steel. The recent surge in research interest in the EAF is driven by the objective of optimizing resource...

257. Efficiency of bio-carbon as slag reduction and slag foaming agent in EAF

Mr Joel Orre (Swerim AB)

08/10/2025, 10:00

Steelmaking - Electric steelmaking

Oral

As the transition towards green steel production is progressing, the direct use of carbon in the EAF for slag foaming and slag reduction has an increasing portion of the remaining CO2 emissions for steel production. In many cases the total carbon consumption in the EAF is increasing with the increasing percentage of DRI and HBI in the charge material mix. It is therefore important to minimize...

385. Simulating the use of renewable and alternative Carbon-bearing materials and hydrogen in the Electric Arc Furnace through a flowsheet model

Prof. Valentina Colla (Scuola Superiore Sant'Anna)

08/10/2025, 10:20

Steelmaking - Electric steelmaking

Oral

The European steel sector is challenged by the ambitious objectives of the European Green Deal, which aims to schive climate neutrality by 2050. Therefore, novel C-lean and sustainable steelmaking processes are being investigated through large-scale pilot projects, accompanied by studies on the possibility to improve operating practices and introduce new components in conventional routes. As...

448. Pneumatic injection of carbon neutral sources in the EAF melting process: a comprehensive overview of the use of new materials

Simone Marcuzzi (MORE srl)

Steelmaking - Electric steelmaking

Oral Presentation

The green steel revolution in the electric arc furnace route requires a reduction in the use of fossil coal and an increase in the use of carbon-neutral sources such as biochar, polymers, and rubber. The use of these new types of alternative materials, have highlighted several aspects that must be considered to obtain a reliable and effective use for the generation of foamy slag during the...
