  Modern machine and plant design and engineering would be impossible without complex analyses and calculations. We perform these in-house. FE-calculations of critical parts, pass schedules, vibration analyses or detail optimisations are part of our engineers’ daily business.
- 3d Laserscanning
  For the benefit of our customers, we are equipped with state-of-the-art laser scanning technology since 2019. Within a few minutes, the 3D scanner creates models of plants or entire factory halls with millimetre accuracy. As a result, less time is lost with on-site measurements and the actual situation can be efficiently compared with new plans.

TRIO to DUO Plate Mill Revamp

Customer: voestalpine Böhler Bleche GmbH & CoKG

After a concept study and a generation of budgetfigures, we received the contract for modernisation of the existing TRIO rolling mill.

The core of the plant, the Trio-rolling mill, was modified to a DUO rolling mill to enable reversing duty. The main drive and some other mill components have been completely renewed. The existing mill housings are still in use. In order to increase production in the future, the roll gap has also been increased. New cooling units, new buildings to accommodate the new electrical system and hydraulic modifications were carried out.

In addition to the modifications of the mill, the project also included various adaptions for the material flow. For this purpose, the tilting tables were adapted on the entry and exit side. A new roller table was installed, for further transport of the plates to the hot leveller.

Scope of Delivery:

/ Basic engineering
/ Detail engineering
/ Technical calculation
/ Documentation
/ Installation- and commissioning support

Technical Data:
Rolling Force:	40.000 kN
Rolling Gap:	440 mm
Barrel Length:	2310 mm
