Primetals to Upgrade Nucor Continuous Caster
US steel producer Nucor Steel Decatur has selected Primetals Technologies for the revamp of the continuous thin-slab caster at its Decatur, Alabama plant.
The project is set to upgrade the segments with wider, more robust frames with improved spray patterns while meeting current quality and production targets.
The upgrade will also see the caster go from a two-roller to a three-roller design, resulting in 50% more bearing capacity.
Primetals highlighted that the upgrade will enable Nucor Steel Decatur to implement dynamic soft-core reduction in the future, improving internal product quality.
The caster will be the first Primetals Technologies-designed continuous thin-slab caster in Nucor, and will be completely manufactured, assembled, tested and commissioned in Alabama.
The project is set to take three years to complete, with Primetals also providing the full spectrum of engineering services for machine design, including engineering analyses for the frames, roller assemblies, support structures, and secondary cooling.
