Slitting line modernization at Becker Stahl-Service, Germany

Danieli Fröhling completed a successful revamp of the shear and the exit guide at Becker Stahl Service GmbH in Germany, a project that included supply of a new gearbox and a fully automatic mandrel changing device. All the new equipment was designed in-house and pre-assembled at Danieli Fröhling workshops in Meinerzhagen, Germany.

With the help of the 3D scan of the existing equipment and the technical audit performed prior to the design stage, Danieli Fröhling ensured an engineering solution that best suited the needed tolerances of the slitting line and conforms with the interface requirements.

The efficient preparation, great coordination and organization of the project team, and flawless execution of work on-site during the shutdown, allowed the on-time project completion. It also ensured that the customer gained safer and better-performing equipment, along with dramatically improved slitting line productivity.

The revamped slitting shear was empowered to cut 50% thicker strips, thus providing 50% increase in production with respect to strip thickness and equipped with a fully automatic changing head. This enables the customer to produce a wider range of products while complying with the market’s more demanding requirements.

The production diameter of the mandrel can be changed in less than 3 minutes, improved from the originally contracted 5 minutes, meaning that Becker Stahl is able to change the mandrel diameter, coil by coil, without affecting production. Thus, highest flexibility is achieved while shortening the delivery time of products to customers.
