Nucor Steel Tuscaloosa has awarded a contract to Siemens to add a new wide temper mill to its existing cut-to-length line. Siemens will equip the 4-high temper mill with hydraulic gap cylinders as well as an electrical and automation package. The automation package will include drives, high-speed stand controller, laser speed sensors for automatic elongation control and an adaptive temper-rolling model. The engineering, manufacturing and installation will occur during 2007. Commissioning of the mill is scheduled to begin in the first quarter of 2008.
In addition to the temper mill, Siemens’ scope of supply includes replacement of the exiting payoff reel, coil car, coil preparation equipment and new entry guiding system.
