Sublance probes
A custom series of sublance probes for BOF control employs various combinations of measurement technologies in a single sensor, (temperature, carbon by thermal analysis, oxygen activity, and solid chemical sample retrieval). Updating thermal and metallurgical models via sublance technology enables Quick Tap decisions, thus shorter tap-to-tap times and a related more efficient production in primary steelmaking.

Brand names: Multi-Lance® and Combi-Lance

Drop Sensors
As an option, and where sublance installations are impossible due to constructional restrictions, the drop sensor is a valuable alternative tool for automatic BOF control. Temperature-only, or combined oxygen and temperature sensor versions are available.
