Sublance probes
A custom series of sublance probes for BOF control employs combinations of measurement techniques in a single sensor, such as temperature, carbon via 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.
Sensor: Multi-Lance
Drop Sensors
As an option, and where sublance installations are impossible due to constructional restrictions, the drop sensor is an alternative tool for automatic BOF control. The QuiK-Tap sensor is released from an automatic loading and servicing device, then charged into the BOF off-gas chute and flying though subsequent channels into the inner vessel doing the measurement job there. Temperature-only, or combined oxygen and temperature sensor versions are available.
Sensor: QuiK-Tap
