The adequate design of ventilation systems for the capture of hot, fugitive releases from ironmaking and steelmaking operations requires good estimation of fume release rates and temperatures, whether it be for short term operations such as scrap charging into an EAF, or for operations that can be adequately characterized as continuous releases, such as melting and refining. There are...
The PURESCRAP project develops sensor solutions for analysis of post-consumer scrap with the aim to enable increased use of low-quality scrap grades (post-consumer scrap) for the steel industry. Sensor stations are built for the two separate processing chains of heavy (cut) and shredded scrap. It includes sensors for chemical analysis, size metrics and object recognition. The sensor stations...
Tenova and Topsoe have developed an innovative solution for waste gas cleaning in Electric Arc Furnace (EAF) operations by integrating Topsoe's CataFlex™ technology with Tenova's iRecovery® system. This solution improves waste gas cleaning performance, addressing critical pollutants such as carbon monoxide (CO), polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDF), and nitrogen...
The recovery of zinc from electric arc furnace dust is primarily carried out in the Waelz process. However, the reaction kinetics within the kiln remain largely unknown as direct measurements or sampling within the kiln are not possible. This lack of insight hinders a comprehensive understanding of the processes and prevents precise optimization of the kiln´s operation conditions.

The system utilizes one or more robotic arms, depending on plant requirements, to remove impurities from recycled scrap during the final sorting phase. By leveraging an innovative multi-sensor system and a Deep Learning algorithm trained on analyzed materials, the system classifies materials on the conveyor based on their elemental composition (e.g., iron, copper, brass, plastic, etc.).

The latest pollutants emission limits imposed by various governments are forcing some important changes in the world of fumes treatment, also in the iron and steel industry.
New technologies, already applied in other sectors, could now find their way also into this industry to comply with those regulations.
With particular focus to the treatment of the fumes from the Meltshop, Danieli is now...
