Optimal process in electric arc furnaces

Recorders provide information related to the “tap to tap” Arc Furnace's operation time. In this article, a heuristic analysis is performed for electric arc furnace operation. At a later stage of the investigation, an optimization of the operation is performed. Each step of the process is analyzed or put into operation according to the conditions of an expert. Under the specified operating conditions, furnace behavior is characterized, and the relationship between voltage levels in the secondary arc and the melting process is identified. Further, a search is carried out in the furnace s feeder, and the specific mechanics in the furnace for “Tap to Tap” decrease are identified. This analysis enables the proposal of a new optimization model, which considers dynamic programming. Part of the proposal is implemented in a 17-ton furnace, used for melting and refining.
