Abstract
	The current project focuses on advanced and innovative analytics of raw materials and recycling materials being used and produced along the entire steelmaking process chain. Alternative reducing agents (ARAs) for the blast furnace (BF) process, such as pulverized coal (PC), are state-of-the-art. The project partners voestalpine Stahl GmbH (vaS) and voestalpine Stahl Donawitz (vaSD) operate systems for a pulverized coal injection (PCI) at their BFs. Injected into the raceway zone of a BF via the tuyères, PC grades show different conversion behaviour depending on their chemical composition. For a deeper understanding of the chemo-kinetics during coal conversion and for a detailed analysis of other solid fuels, such as secondary carbon carriers (e.g., torrefied biomass) a highly sophisticated test reactor (called ARA reactor) was developed in cooperation between vaS, vaSD, K1-MET, and TU Wien. The transformation of steel production from the BF to the direct reduction (DR) route requires an improved and fast analytics of the produce Hot Briquetted Iron (HBI) coming from the DR shaft. The knowledge e.g., about the iron valence in the HBI allows an indication of the DR process efficiency and stability. At the end of the iron and steelmaking process chain, on-line, or at least at-line (by-pass) analysis applications, are not state-of-the-art to characterize generated residues. Dusts and slags must be characterized in a faster way to execute processes changes more efficiently according to the residue composition. Exemplarily, the slag analysis from the ladle furnace (LF), is used to define a change of additives for the LF treatment. Analysis of scrap as an important secondary raw material possibly directly at the scrap yard (scrap supplier site or in the steel plant) represents an effective measure to obtain information about the scrap quality before planning the further scrap logistics (sorting and charging). Spectroscopic measurement systems for scrap analysis should be tested within this project.
