An electromagnetic coil (EMS) external to the furnace and attached to the hearth, generates an inductive field that allows the agitation of the liquid aluminum inside the furnace.
An advanced electromagnetic agitation system, formed by a flat induction coil, which is placed adjacent to the non-magnetic steel plate, and which forms part of the lower hearth of the furnace.
During the fusion of aluminum, electromagnetic agitation is a technology that includes benefits that improve thermal and chemical homogeneity, higher productivity, lower energy consumption and lower generation of slag.
The stratification of temperatures is eliminated, which means less slag formation, by reducing the surface temperature of the bath.
