Sublance is a robust sensor manipulator system designed exclusively for use on Basic Oxygen Process Converters. This manipulator system allows a remotely located operator to take measurements in the steelmaking convertor at various stages in the process.  Typically these systems are equipped with sensor inventory systems along with mechanized loading and unloading.

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.
