Higher product quality from the two-strand slab caster at Galati plant, Romania
Arcelor Mittal Galaty has placed its trust in the technological packages and expertise in revamping projects of Danieli, for the quality upgrade of its 9.7-meter radius slab caster installed in Galati in 1978.
The installation of a new longer mould, an optimized secondary cooling on a new segment 0, and completely new Level 1 and Level 2 systems, supplied by Danieli Automation, will improve product quality by reducing slab defects like sliver, flakes and spider cracks for coils and plates.
The upgrade will be performed during a 21 day shutdown in September 2017.
In-classroom and on-site training will also be provided operator's personnel.
After the revamping the plant will produce 220-250-mm x 700-1900-mm slabs in low-carbon, peritectic, medium-carbon, micro alloyed, high-carbon and silicon steel grades.
Referring to ArcelorMittal Group, Danieli Davy Distington technologies for slab casters have been installed at Industeel and Sidmar in Belgium, Meizieres, Dunquerke and Fos-sur-Mer in France, Tubarão and Acesita in Brazil.
