In the 1st reporting period, requirements and specifications (Fig. 2) were set for all UCs, and preparatory activities were carried out, despite some delays caused by the COVID-19 crisis. The project development progressed as planned with a 6-month extension.
The 2nd period focused on finalizing requirements and specification, and completing basic digitization upgrades. Cognitive solutions were developed, involving various enabling technologies such as data collection and sensor technologies (Fig. 3), tools for data analysis, control, and optimization (Fig. 4), and digitalization infrastructure (Fig. 5)
In the last reporting period, technical solutions were deployed and validated in production environments (predefined UCs), achieving key accomplishments:
• Electric Arc Furnace (EAF) Steelmaking Process: Mathematical models and an optimization framework were developed, improving process efficiency and providing decision support for operators.
• Cold Rolling Mill: A system for supervision, optimization, and condition monitoring was implemented at Acroni. DSS tool assists the operators in adapting recipes, leading to improved process control and product quality.
• Ultraclean Steel Manufacturing: Model-based surveillance systems were deployed at SID and VAS sites, to optimize stirring efficiency and homogenization in LF and RH plants, enhancing overall steel quality.
• Non-Ferrous Industrial Case: A digital cognitive architecture and AI-supported tools were implemented at EIPC to reduce scrap rate, improve efficiency, and enhance material properties.
Furthermore, various training materials were developed to disseminate the knowledge gained to different target groups. These materials aimed to share the expertise and methodologies developed throughout the project. In terms of exploitation and dissemination, the project consortium actively promoted the project results and outcomes. Communication channels such as the project website, social media accounts (Twitter, ResearchGate, LinkedIn), and promotional video were utilized to keep stakeholders and the public informed about the progress and results of the project. Flyers were developed and distributed at various events to promote the achievements of the project. Dissemination efforts played a key role in raising awareness, fostering engagement with relevant stakeholders.
• Process optimization and monitoring by understanding the relation between process parameters and performance indicators (quality, efficiency, energy consumption, etc.),
• Decision support for setting the process parameters to achieve performance indicators,
• Estimation of unmeasured process variables (soft sensors),
• Diagnostics and condition monitoring,
• Prediction of product properties as a function of process parameters, input material, etc.
The mentioned functionalities are a subject of academic research for many years, but practical implementation does not follow the theoretical results from several reasons. Exemplarily, advanced algorithms are demanding in terms of computational power (optimization, identification, machine learning) and data storage capacity (big amounts of data to be stored and processed). By increasing the computational power of industrial controllers and by the possibility of computing on decentralized platforms (e.g. cloud platforms, edge processing units), one of the obstacles for implementation of advanced control systems is significantly reduced.
