Abstract

Models of a 36 MW submerged are ferrosilicon (FeSi) furnace have been developed for the simulation and evaluation of different control schemes. The models developed, describing the present furnace controller, the electrode positioning equipment as well as the dynamics from the electrode positions to the electrode currents and the disturbance environment, effectively forming a FeSi furnace simulator, were then validated for two furnaces as well as for different operating ranges. In this paper, the validated simulator is used to evaluate the benefits of a decoupling controller compared to the present furnace controller which controls the current in each electrode independently.
