Abstracts:

In article the results of computer modeling of pulsed force of electromagnetic (EM) field influence on Wood’s metal melts motion in crucible is described. Changing of average velocity distribution in the middle horizontal plane of crucible and comparison with picture of velocity for steady EM force is shown. Impulses of EM force were made by modeling of periodically interrupting of alternating current (fac=400 Hz) in furnace’s inductors. A steady force of EM field was made by permanent presence of current in inductors. A value of the EM field’s force is equal in both cases. It is shown that pulsed exposure lead to intensification of melts mixing in the volume of the crucible
