The KOCKS RSB® 370++/6 will be integrated into the existing rolling mill at NAS in Ghent, Kentucky as a finishing block after 19 H/V stands. With this setup, NAS will be able to roll straight and coiled SBQ bars, in round and hexagonal dimensions – all in one block. The RSB® will also roll the feeders for the existing wire rod line. With a total mill capacity of approximately 200,000 t/a, NAS will cover a wide and demanding product range. Finished products include round bars (stainless and high-performance alloys) from Ø 12.7 to 103.6 mm, special rebar with 3 ribs from 12.7 mm to 44.5 mm, and hexagon bars from 12.7 to 76.2 mm.
Despite the RSB®, the scope of supply includes KOCKS Blue Box® water cooling lines and the Microstructure Simulator for thermomechanical rolling, while the 4D EAGLE S system, combined with the Size Control System and a remote control for automatic stand and guide adjustments allows a precise closed-loop quality. In the roll shop, the BAMICON Octopus software and hardware supports all set-up processes. Additionally, Shears, Electric and Automation are all included in the Scope of Supply.
The RSB® 370++/6 convinced NAS with its comprehensive production capabilities – including rebar, rounds, and hexagons without size limitations – and its ease of operation. The proven KOCKS portfolio allows for tight dimensional tolerances, superior surface quality, and thermomechanical rolling where needed. With fast stand changes and the one-pass family rolling philosophy, the equipment will make a significant contribution to higher productivity and operational excellence at NAS, also offering a high degree of flexibility to meet customer and market requirements. Commissioning is planned for the third quarter of 2026.
