Smarter melt - Innovative building set for sensors in steel production

Purpose and goal

The aim of the project was to obtain continuous measurements from a steel melt with the help of new ceramic sensors and optics. This has been achieved with results beyond expectations. We have shown new technology for continuous measurement of chemistry and temperature in the melt and have developed new ceramic construction methods for high temperature sensors in steel melt.

Expected results and effects

The results are very good and exceeded the expectation that not only a new optical lance has been developed that can be used for continuous temperature measurement in a steel melt, but also a new optical measurement system for chemical measurement. Two generations of ceramic-based high temperature sensors with refractive metal for thermoresistors and thermocouples have been developed and tested with promising results. The expected effects of the results are gains in process control of steel melts, energy savings and a safer working environment in steel production.

Planned approach and implementation

The project had regular telephone conferences but also physical meetings, bilaterally or with all parties. Early in the project, we chose to focus on chemical analysis. This created delays with the design and development of a completely system. We also had serious delays in material deliveries and material problems with occasional deliveries. Without the frequent telephone meetings, the project would not have succeeded but in the end, it delivered beyond expectations. All parties are happy with the collaboration and see good reasons for new collaborations in different projects.
