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.
