Effective Metal Mixing at a Low Melt Level in a Furnace or Mixer

The problem of increasing the efficiency of melt mixing in a furnace bath or mixer at low melt levels using an electromagnetic mixer installed on the furnace or mixer side is considered. It is proposed to use a transverse magnetic flux mixer as an electromagnetic mixer. A comparative analysis of devices with a longitudinal and transverse running magnetic field is performed. To perform the comparative analysis, mathematical modeling is carried out using the ANSYS software. By means of parametric mathematical models of electromagnetic mixers with a longitudinal and transverse magnetic field installed on the mixer side, it is possible to accurately reflect electromagnetic processes and obtain dependences of electromagnetic forces in the melt, to determine the release of thermal power in the melt and inductor, and power consumption and cosφ for different linear current load and different melt levels in the mixer. Based on the results of mathematical modeling, two types of electromagnetic mixers are compared and best practice advices are provided for choosing the mixer type depending on the initial metallurgical process conditions.
