Horizontal coil compactor. 4 Newsletter 1/2011 Long-product Mills ArcelorMittal Hochfeld orders wire rod mill Temperature-controlled maximum rolling speed of 120 m/s These facilities allow wire rod to be produced over the full size range from 5.5 to 25.0 mm by means of temperature-controlled rolling and at a maximum rolling speed of 120 m/s for 5.5-mm wire rod. This enables ArcelorMittal Hochfeld to acquire a leading position as supplier of wire rod for the following fields of application: automotive manufacture, mechanical engineering, offshore technology, plants for renewable energies and connective elements. Opportunities and benefits n Rolled metallurgical properties such as conventionally annealed wire rod n Wire rod with characteristics comparable with quenched and tempered steel, but with improved formability n Scale which can be easily removed mechanically or chemically n Closer tolerances of 1 /4 DIN n Reduced spreading width of mechanical properties n Coil weight up to 3 t
Commissioning Stahlwerk Annahütte with new cut-to-length group Faultless bars at any diameter Stahlwerk Annahütte, Germany, the oldest existing steel pant in Europe, is pleased about a new versatile and needs-based cut-to-length group from SMS Meer fully meeting the demands of the manufacturer of high-quality steel bars. Constant quality The new cut-to-length group has been put into operation in the bar mill at the Hammerau site in Southern Germany. Ralf Becker, Head of Hot Rolling Mill Divi- sion at Annahütte: ”The shear works flaw- lessly and we have had good experiences working with bars with very different diameters cut.” The cut-to-length group comprises a pinch roll unit and a combined drum-type/twocrank shear as well as a scrap deflector and is able to cut round bars with temperatures up to 1,000 °C. For threaded bars i.e. rebars with a ribbing designed as thread, the temperature is approx. 200 °C and the maximum tensile strength of the bars is 1,800 N/mm2 . High requirements met The shear operates optionally as crank shear or as rotary shear with knife arms and cuts round bars with diameters from 12 to 50 mm. The new shear unit prior to delivery. ”The machines supplied by SMS Meer are highly versatile and exactly meet our high requirements which we are having as supplier of the automotive and tool manufacturing industry. These bar steels are suited for numerous applications and range from alloyed and non-alloyed steels for casehardened steel grades up to and including steels for springs, chains and ball bearings. The range also includes Q & T, cold upsetting and cold working steels,” Ralf Becker stresses. Newsletter 1/2011 5
