The project objectives are to characterise gas stirring during ladle metallurgy using vibration and camera sensors, and to develop innovative signal processing for obtaining representative indices, used as input into online metallurgical models for adjusting and improving the process. DH and...

The objective of this research project was to improve steel metallurgy and quality by optimisation of the ladle stirring process. Throughout the project, the interactions between solid, liquid and gaseous phases involved in ladle stirring were examined. • Melting of alloying materials was...

This collaborative project was coordinated by Tata Steel UK. It involved Gerdau- Sidenor I+D, voestalpine Stahl Donawitz GmbH (VASD), BFI, ArcelorMittal Research and Aalto University (TKK). The objective of this research was to improve steel cleanness, including improvement of the size and...

The objectives of the Promach project were, on the one hand, determination of microstructural effects on machinability improvement technologies for engineering steels at the same strength level, and, on the other hand, definition of a steel design procedure to minimise running costs of...

The objective of manufacturing steel by continuous casting with homogeneous dispersion of very fine oxides (oxide dispersion strengthening) encountered the difficulty of not being able to disperse the oxides during the casting process : this difficulty was due to different technological aspects...

The development of high performance steel grades leads to more and more severe requirements in terms of inclusion cleanness. Steelmakers need to control very early the inclusions present in the liquid state in order to improve the process and achieve the final product quality. Previous studies...

The main objective of this project is to improve the methods for control of metallurgical processes, by introducing online determination of non-metallic inclusion characteristics based on OES-PDA. The work has included method development, software development and several plant trial campaigns....

This RFCS project started on 1 July 2006 and was coordinated by Swerea KIMAB. Other partners engaged in the project were Ruukki Metals Oyj (Ruukki), Rheinisch-Westfälische Technische Hochschule (RWTH), SSAB EMEA (SSAB) and voestalpine Stahl GmbH (voest). This final technical report includes...

An analysis of various options of coal gasification technologies with different gasification media, process parameters and coal types, as well as mathematical and thermodynamic modelling of the planned trials, have been conducted. Moreover, a pseudo-homogeneous mathematical model for the...

Five TWIP steel grades (Fe-Mn-C-N and Fe-Mn-Al-Si-C) were selected, adopting stacking fault energy (SFE) and austenite phase stability as the main metallurgical characteristics for alloy design. The selected TWIP grades were characterised in terms of SFE, mechanical properties, microstructure,...
