Digital Library of Periodicals of National Academy of Sciences of UkraineРезюме: | 3D integral model of eddy currents and electromagnetic forces in the liquid
phase of continuously cast billets with electromagnetic stirring is offered. Take into
account the characteristics of the magnetic field of electromagnetic stirrer (EMS):
currents low frequency 3...6 Hz in the EMS windings and electromagnetic forces field
many times more magnetic fields of eddy currents. As a result we can neglect the
magnetic field of eddy currents and assume that at each point of a massive conductor
the magnetic field is equal to the magnetic field of EMS. In this case the initial system
of integral equations is substantially simplified and its solution reduces to the solution
of two subsystems: a vector integral equation for the density of the magnetization
current on the surface of the EMS magnetic core and system of integral equations for
the density of electric charges on the surfaces of massive conductors; in the resulting
distribution of the density of electric charges is determined the electric scalar potential
in the molten steel; from distribution of vector magnetic potential, the vector magnetic
induction and the electric scalar potential in the liquid phase of billet is calculated the
distribution of vectors of eddy currents density and electromagnetic forces. |
