Reduction in BOS fume losses by the application of X-ray fluorescence measurements*
Diminution des pertes par les fumées au convertisseur grâce à l’application d’une mesure de fluorescence X
In order to develop a new approach for improvements in yield losses, and to control metal skull formation and environmental problems in the Basic Oxygen Steelmaking, a new technique of dynamic analysis of fumes has been proposed. This allowed to validate rapidly the results of investigations of laboratory- scale models and pilot plant operations. The technique has been successfully applied to define the Llanwern process with 76 % less fumes going to the waste gas cleaning and an 80 % recycling rate of the slurry solid phase.
Subject of a lecture at the ATS International Steelmaking Conference 1995 (Paris, 6-7 December, 1995, Session 5).
The work was funded in part by the Commission of the European Union on behalf of the European Coal and Steel Community.
Acknowledgements also to Mr. P. Tily formerly of Warren Springs Laboratory UK, an inventor of the application of XRF to pyrometallurgical processes who guided the British Steel development of a Process Optimisation Device for steelmaking.
