Purpose and goal

The current proposal aims at developing an innovative and flexible measurement system based on fiber optics for temperature and chemical composition measurement of molten steel systems in the metallurgical processes. This includes online continuous measurement and visualization of the molten steel temperature and composition in an experimental laboratory furnace which is already present at SWERIM AB.

Expected results and effects

The development of dual functional sensors, for temperature and composition measurements, will be an important achievement for Swedish iron and steel industry where a radical improvement to the process control and monitoring will be acquired. Additionally, the application of such system in steel mills will ease the sampling procedure of molten steel and creates safer working conditions for operators where manual sampling in close distance to high temperature is no longer required.

Planned approach and implementation

The project has been scheduled for 1 year where it will be executed in 3 work packages during four quarters as follow: WP1: Furnace modification and developing of calibration procedure through lab experiment (Q1-Q2). WP2. Development of numerical algorithms and codes required for interpreting the obtained results for online applications of the fiber sensors (Q3). WP3. Online measurement of both temperature and chemical composition (Q4).
