Hoesch Hohenlimburg implemented a warehouse management system in the coil store downstream of the two pickling lines in 2011. The system enables targeted storage and efficient use of the available storage space. It optimizes crane movements, avoids unnecessary shifting and the associated risk of damage and speeds up loading for shipment. The warehouse management system takes over as soon as a coil leaves one of the two pickling lines. Henceforth it controls the activities all the way down to the loading of the coils on trucks or trains. Therefore it has not only mapped the warehouse management in bay No. 6 but also the complete dispatch activities. The warehouse management system first determines which areas of the warehouse are generally suitable for a particular coil. After this preliminary selection, it checks each one of the available empty spaces in these areas for its general suitability as a storage location for that coil. Source

The current work investigates the impact of pre-deformation temperatures on the microstructure evolution and the subsequent cyclic stress-strain response of high-manganese steel showing twinning-induced plasticity (TWIP) at room temperature (RT). Deformation at low temperatures increases the hardening rate at low to medium degrees of deformation through concurrent martensitic transformation. In contrast, high temperatures promote dislocation slip. Thus, employing pre-treatments at temperatures below and above RT leads to the evolution of considerably different microstructures. Low-cycle fatigue experiments revealed distinct differences for the pre-treated TWIP steels. © 2015 The Authors. Source


Coil tracking is addressed as part of the production data acquisition in its various forms and analysis options. The timely assessment of broadband flat products represents an engineering challenge. This concerns especially the mapping of the process values to the produced meters at the respective sites where the band is subject to thermal or mechanical deformation. This article describes general considerations to get closer to the task, a proven solution and the different benefits for the users. Source

In 2011, Hoesch Hohenlimburg GmbH implemented a warehouse management system (WMS) in the coil store downstream of the two pickling lines. The WMS enables target-oriented storage and efficient use of the available storage space. The system optimizes crane movements, avoids unnecessary shifting - and the associated risk of damage - and speeds up loading for shipment. It creates transparency as it makes all information readily available and all activities intuitively comprehensible. Additionally, the system guarantees a high safety level. Source

During hot rolling Si-containing steels at Hoesch Hohenlimburg form red scale. Even pickling cannot remove the red scale and the resulting stripes can easily be detected and lead to impairments on the surface of the strip. Lab investigations at VDEh-Betriebsforschungsinstitut (BFI) showed that the atmosphere during the transportation of the slab from the descaler to the rolling stand has a significant influence on the red scale formation. A scale detection system detected scale blisters on the surface of the slabs in the hot rolling plant which form red scale during rolling. Source
