Successful start-up of ‘Dream Steel’ rolling mill for rebars and plain rounds

(Vertical Compact Coiling) lines. The walking-hearth furnace is designed for heating 160 x 160mm square billets with lengths of 16 m. With its dimensions, this unit ranks among the world’s largest for reheating of starting material for long-product rolling mills. When planning the layout of the mill, space was allowed for the installation of a billet welder for endless rolling operation and a possible expansion for the production of wire rod. SMS Meer acted as system integrator, supplying all the electrical and electronic equipment, controls and software for the mill automation.

Stefana SpA, a manufacturer of bars and wire rod, awarded a contract to SMS Meer in 2005 for the supply and installation of a complete bar mill for 120 t/h (140 t/h with hot charge). The objective of the project, named “Dream Steel” was to significantly boost production of straight bars and spools. With an annual capacity of 700,000t, this new plant has one of the highest productivities in southern Europe. The product mix of the bar mill includes rebars and plain rounds with diameters from 8 to 16mm produced with the two-slit rolling method, and with diameters from 18 to 40mm produced in a single line. The SMS Meer scope of supply included a walking-hearth furnace, the rolling line, the finishing section and two VCC®

Inline stretching unit

Eurolls’ inline compact stretching unit, LSO 500, is designed for the production of high resistant/high yield wire in accordance with the latest European standards. The insertion of this unit into an existing production line, to produce cross wires in mesh line or longitudinal wires in lattice girder lines for example, permits inline production of high resistant/high yield wire, ready to be successively processed into its final welded or bent format.
