Primetals Technologies to convert a continuous tandem line into a pickling tandem line at voestalpine’s steel plant
Primetals Technologies has received a contract from voestalpine Stahl GmbH, a company of the Steel Division of voestalpine AG, to convert the existing continuous tandem line into a pickling tandem line at voestalpine’s site in Linz. The package includes core components, process machinery, and their integration into the existing plant.
Primetals Technologies receives final approval on drives upgrade for Nucor Steel Arkansas hot strip mill
Primetals Technologies has received the Final Acceptance Certificate (FAC) for its F5 and F6 main drive upgrade project with Nucor Steel Arkansas of Armorel, Arkansas. This completes the third phase of the total project: full replacement of the hot strip mill’s six main mill stand drives.
The main challenge in replacing the drives was to execute the changeover within the customer’s nine-day maximum outage time. To meet this extremely tight timeline, the very large drives had to include identical take-over points for all existing, equally large cables. The new Siemens Sinamics SL 150 drives also needed to start up and achieve full production immediately, without any ramp-up time. The team achieved hot commissioning 15 hours ahead of schedule.
Hoa Phat expands steel plant in Vietnam with comprehensive production line from Primetals Technologies
Hoa Phat Dung Quat Steel JSC has awarded a major contract to Primetals Technologies for a new production line at the steel plant in Dung Quat, Quang Ngai province in Central Vietnam.
The steel market in Vietnam is one of the world's most expansive and dynamic. With an increase in capacity of 5.6 million metric tons per year, Hoa Phat will be able to address the rapidly increasing demand for steel products in Vietnam. The project consists of two slab casters, one hot rolling mill, modern automation systems, and comprehensive digitalization solutions. A fully integrated quality control system, intelligent digital assistants, and scheduling solutions will ensure high quality, productivity, and flexibility. The start-up is expected for 2024. This contract represents the second major order for casters and hot-strip mills received by Primetals Technologies in 2021.
NLMK issues FACs for new BOF off-gas system supplied by Primetals Technologies
Primetals Technologies has received the final acceptance certificates (FACs) from NLMK Group in Lipetsk for the construction of off-gas systems at LD converters (BOFs) No. 2 and 3 at steel plant LD2. The project's targets were: reducing emissions at the steel plant to levels lower than European standards; improving the heat-recovery system to supply steam to the existing network; using the converter’s off-gas for further utilization; and increasing productivity.
HKM grants final acceptance for two new ladle treatment stands from Primetals Technologies
German steel producer Hüttenwerke Krupp Mannesmann GmbH (HKM) has granted Primetals Technologies final acceptance for two new ladle-treatment stands. The plants were built at the BOF steel plant at the Duisburg-Huckingen site. The heating stands are designed for 5.2 million metric tons of liquid steel per year in fully automated operation and are therefore well prepared for further digitalization. The use of copper-clad lids increases service life and ensures the quality of the produced steel. LiquiRob systems manage tasks such as temperature measurement and sampling which were carried out manually in the past, thus increasing operational safety. The installation of the new ladle-treatment stands reduces operating costs in the steel plant. In addition, the phosphorus content of the melts can be reduced and higher alloying percentages are now a possibility.
