In-Situ Monitoring of Oxygen Concentration and Gas Temperature in a Metallurgical Process Using Diode-Laser Spectroscopy :

• Increased demands on quality control, reduced production-time, energy savings and reduction of green-house-gas emission in various metallurgical processes have created an interest for new methods to monitor and control the processes. By using Tunable Diode Laser spectrometers the gas temperature as well as the concentration of 0 2, CO and C02 have been monitored. Laboratory experiments were carried out in a specially designed high-temperature furnace at MEFOS to determine a set of absorption lines suitable for simultaneous 02ffemperature and CO/COz measurements. Field trials were carried out in an Electric Arc Furnace and a reheating furnace.
