OMiAS - Optical online measurement method for in-situ analysis of the chemical composition of a steel melt during liquid steel production

Initial situation:

  • The chemical composition has a major influence on the properties of steel
  • Until now, no operational technology is available for online analysis of the composition
  • The laboratory analysis of steel samples to determine the process status is only available with a delay of about five minutes, which results in a significant extension of the process time and thus a loss of productivity

Project targets:

  • A fibre optical online measurement method for determining the concentration of chemical elements in a steel melt is to be developed and tested on a pilot scale

Innovative approaches:

  • The basic idea of ​​the measuring method is to record the reflection spectrum inside a steel melt via an immersed optical fibre
  • The shape of the reflection spectrum is used to determine the element concentration in the melt using data-based evaluation algorithms

Benefits for the industry:

  • Immediate provision of analysis results for online process control
  • Reduction of process times
  • Increased productivity
  • Reduction of energy and material consumption
  • Improved work safety
