Blytheville Arkansas USA based Nucor Yamato Steel Company has granted SMS group the Final Acceptance Certificate for the successful modernization of the heavy beam mill No 2, on which wide-flange beams and I-beams are produced. 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 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. Nucor Yamato Steel 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.
In addition, a hydraulic adjustment system of the bottom roll for the breakdown stand was supplied to increase the flexibility in the rolling process. It allows the bottom roll to be adjusted from pass to pass, is used for roll force measurement as well as for overload protection and as roll unjamming device. Furthermore, the scope of supply includes reinforced axial keeper plates for the breakdown stand that allow clearance-free axial clamping of the chocks.
Nucor Yamato Steel also operates a medium section mill at the same location, which was modernized by SMS already in 2014. The two rolling mills have an annual total capacity of 2.4 million tons of finished products.
