Optimization of the Melting Process of an Electric Arc Furnace by On-Line Offgas Measurement

An often-neglected process step in electric steelmaking is the monitoring of the offgases from the electric arc furnace (EAF), although such monitoring brings enormous potential for process optimization. Precise knowledge of the gas flow and the CO2/CO ratio enables plant operators to control the melting process sustainably and efficiently. PROMECON developed a non-extractive, real-time and drift-free measurement method that makes exhaust gas analysis at the EAF easy. The digital measuring system determines the measured values in real time and thus enables very short reaction times for process control. The consequences are high savings in energy, fewer faulty batches and higher steel quality.
