On-line eddy current testing of hot CC slabs : towards the inspection of the whole product surface
Contrôle en ligne par courants de Foucault de brames de coulée continue à chaud : vers l'inspection de la surface totale des produits
In order to achieve a non destructive testing of the whole surface of CC slabs, the option of two independent eddy current devices has been taken.
The detection of transverse cracks on slab edges has been industrial since 1985, bringing drastic economical savings and making direct charging rate evolve towards 100 %.
The newly developed inspection of large sides looking for longitudinal cracks has given very good results, thanks to eddy current imaging, during on-line qualification trials.
