Revamp of heavy beam mill No. 2 at Nucor-Yamato
Nucor-Yamato Steel Company (NYS), based in Blytheville, Arkansas, USA, has granted SMS group the Final Acceptance Certificate (FAC) for the successful modernization of the heavy beam mill No. 2, on which wide-flange beams and I-beams are produced.
The goal of the revamp was to strengthen further NYS’s leading market position in the structural steel sector by expanding the product range, increasing production and processing new high-strength steel grades.
The modernization particularly focused on replacing the existing conventional UR-E and UF stand arrangement by a compact three-stand tandem reversing mill of the type CCS (Compact Cartridge Stand) 1500.
The new stands are characterized by higher rolling forces, hydraulic adjustment under load and a fully automatic quick program change function. Furthermore, in the CCS mill stands, both the old existing rolls and bearings can be used as well as new rolls with larger bearing diameters.
This reduces roll costs and represents a major advantage of the CCS stand design. NYS is thus able to manufacture heavier products and expand its product portfolio. The scope of supply also includes roll shop equipment and a new automation system for real-time process control.
