Danieli to upgrade bar mill at Hennigsdorf plant

Hennigsdorfer Elektrostahlwerke GmbH (Riva Group) has contracted Danieli to modernize its bar rolling mill in Germany, to produce high-quality, smooth rounds from 14–80 mm diameter, and round bars for reinforced concrete from 9.5–40 mm.

The two-stage project will start with the installation of a new intermediate mill featuring H and H/V convertible stands to match a new roll-pass design for the production of round products for reinforced concrete and quality steel bars.

The second stage will involve replacing the finishing train and inserting a compact sizing unit that will improve tolerance and ovality on the final product down to the ¼ DIN, where all products will be finished to minimize groove / size changing at the intermediate mill. This will ensure high plant efficiency and enhance mill productivity.

The CSU “ready-to-roll” fast-automatic mill stand change system will allow product changes in less than 5 min, easing the production of small lots.

The new equipment is designed to accommodate a future expansion of the products including flats from 50x6 to 140x60 mm.

Danieli Automation will supply a complete automation system and equipment, including a HiProfile Lite measuring system with the QShape technology.

Plant startup of the two stages is scheduled for Q1 and Q3, 2018.
