The net zero emission target for steelmaking is pushing toward the adoption of breakthrough technology. The process route based on iron ore pellets direct reduction requires also a fine tuning of the subsequent melting step in EAF. This, in turn, will require the adoption of modified operating practices, tailored to the EAF input charge of materials.
The blending of DRI and scrap is a way to...
To comply with tomorrow’s more stringent committed environmental targets for steelmaking, the world witness one of the most fast-paced transitions in the history of steelmaking. DRI-based EAF route will play a crucial role in transforming green steel production thanks to its carbon footprint, which is significantly lower than a blast furnace, while still ensuring the highest product quality....
The acid gangue components in agglomerates used in the Direct Reduction–Electric Arc Furnace (DR-EAF) steelmaking route, particularly SiO₂ and Al₂O₃, have a significant impact on EAF performance. These oxides influence slag characteristics such as volume, foaming capacity, and viscosity and affect key operational parameters: metallic yield, electric energy and oxygen consumption, refractory...
Green steel requires massive investments into new decarbonized production technology and green energy supply, yet renewables are cheapest to produce in remote locations far from established steel production sites. Is it thus more sensible to relocate the energy intensive iron production step near renewable energy, or should investments aim at bringing green energy efficiently to the existing...
The global shift toward decarbonised steel production with the increasing use of low-grade iron sources has driven interest in introducing electric smelting furnace (ESF) to process low-grade direct reduced iron (DRI) and generate ESF hot metal as a replacement of the blast furnace (BF). At the same time, the gradual scarcity of high-quality scrap has increased interest in using hydrogen based...
Tata Steel Netherlands (TSN), aims to reduce the CO2 emission by 40% and enhance circularity by increasing the scrap usage to 30% by 2030. These targets will be achieved by replacement of one blast furnace with an Electric Arc Furnace (EAF) which utilise Direct reduced iron (DRI) and scrap as charge material.Increasing scrap usage in EAF steelmaking is essential for enhancing circularity and...
