In March 2020, Primetals Technologies has received the final acceptance certificates from Acciaierie Valbruna for the mechanical and electrical revamping of the AOD converter at its production facility in Bolzano in Italy. One of the main reasons for the revamping was the modernization of the converter trunnion ring and tilting drive including a new shrink fit connection. Further on a new process optimization system level 2 was installed by Primetals Technologies, and the process control system level 1 as completion of replacement of mechanical and electrical parts for the trunnion ring and tilting drive. The level 2 system was adjusted and aligned to Valbruna’s production requirements via remote connection by the experts of Primetals Technologies from their offices in Austria. Additionally, the whole existing level-1-system was aligned and updated in cooperation with Valbruna. The revamping has improved the process stability, the production flexibility, and reduced the maintenance efforts for the AOD converter.

After several years of operation, Acciaierie Valbruna decided to install a level-2-system and to modernize the trunnion ring and tilting drive of its AOD converter in Bolzano, Italy. The new level-2-system allows interfacing and integration of the AOD refinement process with the steel plant upstream (arc furnace) and downstream LF as well as continuous casting activities, where another level 2 system of Primetals Technologies is installed. The system also makes it possible to archive, search and elaborate all process data as well as the availability of the necessary reporting according to Valbruna's needs.

In the late summer of 2019, Primetals Technologies completed the mechanical and electrical modernization of AOD by a new trunnion ring and tilting drive gear to enable a shrink fit connection, new support bearings and a complete update of the process control system level 1. In parallel a new process optimization system level 2 was installed. Despite a challenging project management for both Primetals Technologies and Valbruna, the work was completed on time and with full customer satisfaction.
