Optimization-based Online Decision Support Tool for Electric Arc Furnace Operation **This work is supported by the McMaster Steel Research Center (SRC) and the McMaster Advanced Control Consortium (MACC).

Electric arc furnaces (EAFs) are broadly used in the steel industry for producing different grades of steel by melting steel scrap and modifying its chemistry The EAF process is highly energy intensive and involves a low level of automation. The decisions associated with the amount and timing of injected inputs depend heavily on the EAF operators. Although the operators’ practical experience is crucial in running the EAF, important …
