Salzgitter Flachstahl GmbH has granted SMS group the contract to supply a comprehensive technology package for its hot strip mill in Salzgitter. Following the systematic mechatronic modernization of the hot strip mill in recent years, Salzgitter is now working on state-of-the-art control systems and process models from the X-Pact® product family.
Alongside a number of new functions and a harmonized tool environment, operated on the most advanced automation platforms, the scope of supply also includes the X-Pact® Integrated Temperature Model as a learning, self-optimizing process control feature. This combines all process steps to form a superordinate temperature model and creates comprehensive recommendations for a better product quality and plant productivity. Energy-consumption-oriented operating modes are included, as is the forward calculation of entire rolling plans for manufacturing high-quality and temperature-sensitive steels with overall improved product characteristics. At the same time, the X-Pact® Plant Pacing system optimizes the throughput and productivity of the entire plant.
“For Salzgitter, it was and continues to be vital to have a partner that not only has impressive technical expertise, but also offers us the prospect of advancing together beyond the current state of the art. As well as the right commercial framework conditions, we found this combination of technical excellence and shared growth prospects at SMS,” says Achim Pekrul, project manager at Salzgitter.
In addition to the level 2 automation, the integrated strip guiding control system, known as X-Pact® Centerline Control, is also part of SMS’s scope of supply. This solution uses a camera system, the X-Pact® Sense hotCAM, to find deviations in the strip flow and calculates correction signals for each mill stand. As a result, manual interventions by the operating personnel to avoid unscheduled downtimes and malfunctions are significantly reduced. The technology package for Salzgitter Flachstahl is completed by the new X-Pact® PEAK control concept, which helps to boost capacity and productivity levels in the rolling mill.
The hot strip mill is a relevant component of the production process at Salzgitter Flachstahl. As the perfect partner for integrated lifecycle services, SMS group is making a major contribution to the further development of the technology and process engineering for more sustainable, more profitable and self-optimizing plant operations.
