Final report on Contract no 7215-AA/803, 603, 109, 1 July1996 to 30 June 2000

The major objective of this project was to utilise previous ESCS-funded work on the use of X-ray fluorescence (XRF) techniques as an aid to developing methods for reducing the fume losses from the BOF process. The XRF monitoring technique has been demonstrated and is now commercially available.

BOS trials at both Corus UK and Corus IJmuiden have demonstrated the importance of slag formation and quality on the level of vessel fume emissions. Reductions of around 10% in vessel iron losses have been demonstrated and implemented.

The XRF technique has also been used to monitor gas cleaning plant performance in terms of atmospheric emissions after gas cleaning. Whilst the technique in this application is not fully developed, it has proved useful in assessing plant fault conditions. For the reduced vessel emissions demonstrated in the project, there was no significant impact on gas cleaning plant performance.

The effect of top charged additions to the BOS has also been studied. It is concluded that top charged additions increase the local level of vessel emissions.

Techniques for the agglomeration of BOS slurries for recycling have been examined. Both briquetting and extrusion methods have been assessed. Trials have been carried out to improve understanding of the potential for slurry diversion related to the zinc content of the slurry. Recycling of briquetted BOS slurry has been adopted by Corus UK.
