The electromagnetic processes in an apparatus for electromagnetically refining aluminum melt with conduction excitation of current in the melt are simulated. The numerical calculation is carried out using the Maxwell finite element software package. Based on numerical calculations, the equivalent circuit parameters and the main electromagnetic characteristics of the apparatus are determined. From the distribution of bulk electromagnetic forces in the melt, the terminal velocities for particles of different diameters are obtained. It is shown that the operating voltages are in the range from 0.1 to 6.0 V depending on the current and contact resistance values. The preheating of metal in the trough by conductive supply of electricity in the system under study can only be used jointly with another kind of heating. With the operating currents in the secondary circuit higher that 2000 A, the terminal velocities of particles 30—50 m in diameter are in the range 1—4 mm/s. This means that efficient removal of impurity particles with a diameter of 30 m or larger can be achieved in the apparatus under study. With the secondary circuit current less than 1500 A, the particle migration direction is governed by the buoyancy force, which also governs the (inefficient) natural particle sedimentation process.
There has been set and analytically solved task on calculation of the electromagnetic field in the area of the "cylindric inductor -channel with liquid metal" system. The inductor part includes a polyphase winding with electric current that enables generating the rotating magnetic field. The solution for electromagnetic field vector has been found in the Fourier series of a complex form using Bessel functions. The task was solved in a 2D design using the cylindrical coordinate system. There have been obtained the relations of the current density in the channel metal, electromagnetic power and moment to the parameters and modes of system operation. The electromagnetic rotator for the liquid metal can be used to introduce fine metal particles (chips, sawdust) into the reverberatory melting furnace.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
