dc.description.abstract | This report details work undertaken to correlate data obtained from inspection systems in the casting
plant, scarfing area and rolling mills in order to track product quality throughout the steel mills. The
project was a collaboration between Corus UK Teesside Technology Centre, Arcelor and Scuola
Superiore Sant’Anna (SSSA) which was coordinated by Corus.
Co-ordination meetings were held twice a year with the partners, at each of the partner sites. Although
the project started late due to awaiting RFCS approval, the objectives were completed according to the
Technical Annex of the contract which can be found in Appendix 5. All the Tasks were completed by
the end of the project, with the exception of Task 2, from Work Package 2 and Task 3 from Work
Package 3. Reasons for not completing this work are found in the following section and these were
highlighted in previous 6-monthly reports and whilst presenting the mid-term report to the TGS9
Committee.
This project did not exceed the overall budget and the project costs from each of the partners were
approved after the submission of the mid-term report. Final, audited cost claims are being submitted.
Two main inspection systems were tested for use in the continuous casting plant. The first was
Conoscopic Holography, which was developed from an industrial prototype where only a partial width
of the slab surface was inspected to a system where the entire slab top and bottom faces were inspected.
The second was a hybrid Laser-EMAT (ElectroMagnetic Acoustic Transducer) system. This system
was demonstrated to work on hot moving steel. Significant work was conducted to analyse data
automatically so that a real-time, on-line inspection system could be conducted on plant.
Work was undertaken to inspect slabs in the slab yard using a variety of techniques which were
compared. This inspection work was used to measure how well the caster was performing, by data
mining plant signals and, for Arcelor, equating these with the conoscopic holography readings. Slabs
were successfully tracked through the steel mill by the partners and comparisons were made from
upstream inspection to the downstream Parsytec system and inspection of the final product.
Different scarfing practices were compared. In some instances, for certain steel grades, it was found
that scarfing was no longer necessary.
Metallographic work was undertaken to assess defects in steel samples to determine the cause of
cracking. Upon recommendations from this project, plant practices were changed and the defects no
longer arose. | spa |
