Project HIYIELD - Efficient technologies for sustainable steel production

Erkrath 20.04.2023 - The European research project HIYIELD ("Highly Efficient Technologies for Increased Yields in Steelmaking Processes and Reduced Environmental Impact") aims to make steel production more sustainable, efficient and circular. The focus is on significantly increasing the amount of scrap used in three central European steel production processes - while maintaining the same high product quality. The project is being coordinated by the Royal Institute of Technology in Stockholm (KTH) under the direction of Prof. Björn Glaser. The project was launched in July 2022.

Aims of the project

The HIYIELD consortium develops practical, industry-oriented solutions with the following focal points:

  • Optimization of scrap quality through innovative technologies for the removal of impurities and the targeted use of alloying elements
  • Increasing the use of scrap through improved identification, classification and traceability in terms of the circular economy
  • Ensuring product quality through optimized batch composition and precise melt analysis - even with a high scrap content

Technological approaches

State-of-the-art digital and analytical methods are used to achieve these goals:

  1. Deep learning-supported image processing for scrap identification and quality assessment
  2. Digital scrap information cards for seamless traceability in the supply chain
  3. Direct melt analyses for real-time monitoring of steel quality during the process

The contribution of MINKON

As part of the HIYIELD project, MINKON is developing an innovative sampler and associated peripheral systems that enable direct analysis of molten steel. This new type of sampler can be flexibly integrated at different points of use and delivers rapid analysis results. The associated time savings contribute significantly to process optimization and resource conservation - a decisive advantage for modern, sustainable steelworks.

HIYIELD is thus making a significant contribution to the climate-friendly transformation of the European steel industry - through greater resource efficiency, reduced environmental impact and increased competitiveness.
