iBOF® Endpoint Control

Poor endpoint control reduces yield & productivity, elevates tap [O] and increases slag FeO & tap alloy consumption. Tenova’s Endpoint Control Module utilizes off-gas analysis, velocity & temperature sensors, heat specific data and a fundamental real-time mass & energy balance model to accurately predict endpoint steel & slag chemistry.

Overview

To ensure a robust, low cost endpoint solution, the iBOF^® Endpoint Control Module includes a real-time Mass & Energy (“M&E”) balance software that incorporates fundamental thermodynamic & kinetic equations to better model the non-equilibrium near-end of blow conditions when carbon, iron & phosphorous oxidation can occur concurrently.

Tenova’s patented NextGen^® hybrid extractive/laser off-gas analysis technology, proprietary off-gas velocity, temperature and static pressure sensors and a PLC link provide all the measurements needed to close a precise real-time M&E Balance.

NextGen’s multipoint capability can reduces hardware, installation cost & maintenance by enabling continuous, simultaneous off-gas analysis on multiple BOF’s with just a single central cabinet.

NextGen^® hybrid technology ensures ultra-fast analytical response times and no lost signals by combining Tenova’s highly reliable, industry proven extraction technology to clean the off-gas before using
self-calibrating lasers and other analytical devices to provide full spectrum CO, CO₂, H₂, O₂, H₂O & N₂ analysis
