The new HD (High Definition) spray technology from SMS group was implemented and successfully commissioned in the two-strand slab caster at ArcelorMittal Bremen during November and December 2017.
SMS group retrofitted the two strands of the vertical bending caster one after the other and put them back into operation within one month of one another. The goal of the retrofit was to improve secondary cooling and slab quality.
The HD spray system developed by SMS group is a scalable water distribution and control system which – compared to conventional solutions – requires far less space and pipework.
The SMS group concept of control circuits across the width of the slab that can be individually activated and deactivated is already being successfully applied in a great number of plants.
Pneumatically operated pressure control valves and the related automation system form the centerpiece of the HD spray system. The secondary cooling water is distributed and controlled only just before the cooling nozzles.
SMS group’s scope of supply comprised the entire basic and detail engineering, delivery and erection of the HD spray system and the new segment piping, as well as supervision of the commissioning.
