TENOVA’S INTELLIGENT i BOF® TECHNOLOGY, A MODULAR PACKAGE FOR BOF PROCESS IMPROVEMENT

This paper will provide an overall technology update on Tenova’s modular i BOF® technology package for improved endpoint detection (Carbon and Temperature), slop detection and auto-tapping control, with a primary focus will be on Tenova's Slop Detection System (SDS). Accurate Slopping prediction is a critical tool in the operation of a BOF. It provides the steelmaker with an additional protective system to increase yield & productivity while reducing operating costs. Tenova Goodfellow's i BOF® slop-detection technology uses lance vibration analysis with real-time alerts to give steel makers advance warning of the onset of a slop and a measurement of the slop severity. The system is designed to provide direct feedback control of lance position and oxygen flow rate, for rapid mitigation of potential slopping events. This paper will provide a summary on how the i BOF® technology package has been implemented, including trials and general results.
