Abstract
The paper considers the influence of low-frequency pulsed force of an electromagnetic field on the formation of a solidifying metal structure, investigated experimentally. Pulses in the range from 0.1 to 10 Hz were applied to the melt, during the ingots growth in the cylindrical volume, to create the conditions of the forced convection. The final metal structure and deformation of the samples free surface, solidified in different conditions was analyzed. The reduction of porosity in metal ingots was stated for the cases of forced convection under the pulsed frequencies from 0.1 to 1 Hz, in comparison to the structure, formed by permanent electromagnetic stirring. The specimens, grown under the pulsed forcing with equal time of the pulses and the pauses have concave free surface, as well as in the cases of natural convection and permanent stirring. A flatter form of the free surface was obtained during the solidification process under the short pulses of electromagnetic force.
