Situation
Oxygen activity is an important parameter for the assessment of melt quality
• Short-duration potentiometric measurement of oxygen activity by means of
disposable immersion probes
• Still insufficient information about current oxygen activity in the melt
Solution
Continuous monitoring of oxygen activity by means of a new type of mobile electrochemical measuring technique
• Avoidance of electrode polarisation
• Immersion probes for multiple measurements and continuous use
• Flexible adaptation of measurement cycles to metallurgical process control
conditions
Operational use and benefits
• Continuous as well as random monitoring of oxygen activity in melts
• Flexible use at metallurgical vessels throughout the process chain
• Measurement-data-based analysis of processes
- Early knowledge of melt quality
- Optimisation of processes through shortening of process times
- Reduction in the required amount of deoxidants
