Siemens VAI to Upgrade Badische Stahlwerke Wire Rod Rolling Line

09/23/2011 - Badische Stahlwerke GmbH, at Kehl, Germany, has selected Siemens VAI to modernize the automation system of the two-strand wire rod mill, and to install two new rod outlets. The project will be carried out in three phases from 2011 to 2014 during scheduled annual shutdowns.

Badische Stahlwerke GmbH, at Kehl, Germany, has selected Siemens VAI to modernize the automation system of the two-strand wire rod mill, and to install two new rod outlets. The project, which is expected to be finished in early 2014, will be carried out in three phases from 2011 to 2014 during scheduled annual shutdowns.
 
Siemens VAI’s upgrade of the Badische Stahlwerke wire rod mill, which mainly produces base material for concrete reinforcing bar, will result in an increase in production capacity and a broader spectrum of qualities and sizes due to increased automation and the possibility of thermomechanical rolling.
 
The first phase involves replacing the existing automation system of the 13 stands of the roughing and intermediate mill with the Siroll LR automation system, based on Siemens PCS7 software, to provide fully automatic control and easier maintenance.
 
In the second phase, Siemens VAI will erect the two new rod outlets, each with a six-stand and four-stand Morgan No-Twist mill, 10 Morgan Intelligent Pinch Rolls, high speed trimming shears, Morgan High Speed Laying Heads, Morgan Stelmor conveyors, and a vertical coil handling system in preparation for the third phase, when the new equipment will be connected to the existing mill and commissioned in early 2014. The Siroll LR automation system will be extended to the two new rod outlet control systems with mechatronical packages.
 
Rod speed guarantees are up to 110 meters per second, and the coil handling system will produce a coil every 20 seconds, resulting in a production rate of up to 300 tonnes per hour. Siemens is responsible for all erection and commissioning of the mechanical and electrical equipment in a turnkey operation.
 
The planning and execution of related infrastructure works and civil engineering, as well as the installation of auxiliary facilities such as the water system, will be undertaken by BSW.
 
Founded in 1955, Badische Stahlwerke GmbH produces reinforcing bar and wire rod products for the European construction market. The company runs an EAF-based integrated production site in Kehl in the German state of Baden-Wuerttemberg. Final products are rolled in a bar mill and a wire rod mill, respectively.
