Improvement of slab quality under highly productive operation at SMI Kashima No.3 caster*
Amélioration de la qualité des brames avec une productivité élevée sur la machine n°3 de Sumitomo Kashima
This paper reviews the new systems and technologies applied in No. 3 continuous caster, at Kashima steel works so as to improve and guarantee slab quality in high speed casting :
- –
non-metallic inclusions were reduced with the installation of a larger tundish and the AMEPA ladle slag detecting system ;
- –
the meniscus level control was improved with an eddy-current sensor, an optimum level control system and a stepping cylinder for the tundish sliding gate ;
- –
detection of unequal molten steel flow in the mold with the two eddy-current multi-sensors improve the grading of slab quality.
