The investment is part of a major modernization project aimed at increasing production flexibility, enhancing product quality, and improving efficiency. 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 200,000t/a, NAS will cover a wide and demanding product range. Finished products include round bars (stainless and high-performance alloys) from Ø 12.7mm to 103.6mm, special rebar with 3 ribs from 12.7mm to 44.5mm, and hexagon bars from 12.7mm to 76.2mm.

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.
