In steel application
Monitoring oxygen activity throughout the steel making process is essential for production control and final as-cast quality. In less than 10 seconds, our expendable oxygen sensors measure the melt's oxygen activity over a wide concentration range in areas from furnace tapping, through ladle refining and continuous casting.

In steelmaking slag application
Quality and special steels are refined through close control of ladle top slags. Knowledge of the slags' oxidation potential with respect to the liquid steel oxidation state can be employed to improve alloy recovery, desulphurisation ,non-metallic inclusion capture and lining wear. Based on Celox oxygen probe technology, a special liquid immersion sensor measures the slag oxygen activity and predicts the FeO content in a few seconds. For off-line oxygen activity measurement from a solid slag sample a dedicated analytical system is offered.

For foundries
Final graphite shape and matrix structures of iron castings are closely related to the iron's oxygen activity. Additions of magnesium, among others, are used for vermicular or spheroidal graphite structure crystallization and are related to the oxygen activity of the iron. A special Celox-style oxygen sensor can be used to control the production of vermicular graphite iron known as CGI, compact graphite iron.
