SUMMARY:Revamping of 330t BOF converter at AM gent:  Mastering the logistics
DESCRIPTION:"One of the two 330t BOF converters at AM Gent, Belgium came to the end of lifetime and in 2018 Primetals Technologies was awarded with the contract to revamp the converter. Focus topic during the design phase of the new converter was to optimized reaction volume and shape of the converter vessel to further improve yield and energy efficiency towards absolute benchmark levels. Well proven equipment solutions like the Vaicon Link 2.0 vessel suspension and the Vaicon Drive for converter tilting were employed for the new converter. Existing equipment was reused as much as possible and e.g. the existing Vaicon Stopper for slag retention at tapping was installed with minimum modifications only on the new converter.
Another focus topic in this project was the optimization of the project execution and especially the installation sequence. To minimize pre-assembly works on site and consequently the risks for quality issues and time delays the converter was fully assembled at the manufacturers site and transported in two pieces – the lower part of the vessel with the vessel suspension and the trunnion ring fully assembled and the upper cone of the vessel. Hence, onsite in final position only one circumferential weld was required. An optimized transport concept including lifting of fully assembled converter with a total weigh of more than 380t above a pipe bridge were required. Thanks to good planning and preparation, the tight 35-day timeline for the revamp could be met without any interruption in the ongoing production of the second converter in the melt shop during the shutdown.
In the paper the main design features of the new converter as well as the highlights of the installation job will be presented."
