NineSigma, representing a global metal engineering company, invites proposals for a novel, top-down real-time analysis of molten steel in a metallurgical reactor.
In metallurgical reactors, the temperature and composition of molten steel is measured to determine the optimum conditions for further processing. Typically this measurement is via a thermocouple lance and is manually operated. A sample is taken, analysed, and then a decision is taken. This process is time-consuming and involves potentially hazardous steps.
Recent advancements using LIBS technology (Laser Induced Breakdown Spectroscopy) has enabled the critical parameters to be measured in real time. However, the commercially available devices¹,² are side-on to the furnace and require significant precautions to prevent hot metal splashes and nozzle clogging.
The ideal solution would be a LIBS based system (or alternative in-situ measurement technique) which can be installed either from the top or the bottom of the furnace as indicated in the diagram above and provide the required measurements.
