Tenova’s iBOF® is a breakthrough technology designed to reduce GHG emissions while improving yield, productivity and scrap-melting capability and cutting operating costs.
Tenova's iBOF®, "intelligent Basic Oxygen Furnace", is breakthrough technology that combines highly reliable off-gas analysis, novel sensors & process models to provide an unparalleled level of control & efficiency.
iBOF® is a modular technology that can be customized to meet the specific needs of each BOF steel making plant by employing a combination of several technologies:
Module 1 - End-Point Detection
The innovative features of iBOF®, uses NextGen® technology as the base, along with proprietary off-gas sensors to measure temperature, flow and pressure and BOF process control models that are designed to enable "Blow & Tap" practice without additional cost and delays associated with sub-lance technology.
Module 2 - Intelligent Slop Detection System (iSDS®)
A unique and proven technology that uses lance vibration analysis with real-time alerts to give operators advance warning of the onset of a slop and a measurement of the slop severity. It is designed to provide direct feedback control of lance position and oxygen flow rate for rapid mitigation of the effects of a slop.
Module 3 - Optimized Post-Combustion
iBOF® post-combustion uses NextGen®, multi-point analysis together with temperature, flow and pressure sensors and a dual-flow lance with independent control of primary and secondary oxygen to control secondary oxygen flow-rate, penetration and timing. The result is optimal post-combustion efficiency and scrap-melting capability with minimal refractory or lance wear.
Module 4 - Automatic Tapping Control
Through operator-assist mode or a fully automatic mode, iBOF® auto-tapping technology uses advanced image analysis together with process models to control tapping practice, resulting in decreased tap time and variability, reduced slag carry-over and ferroalloy and aluminum consumption.
iBOF® technology delivers unprecedented value and an unparalleled level of customized control by employing a combination of reliable offgas analysis, novel sensors and process models linked by a comprehensive automation system.
iBOF® is a modular solution available as a unified package or as standalone systems designed to meet specific customer needs.
