Abstract

In order to analyse the interactions of non-metallic (non-conducting) inclusions in (conducting) liquid metals in the presence of an electromagnetic (em) field, a simple system of two spherical particles was studied. This study dealt with particles in a row in an oblique configuration with respect to the dc em-field. The interaction force between the particles and the migration force exerted on them were calculated, taking into account the effect of electromagnetically driven flow (em-flow) of the liquid. The state of em-flow had essentially the same features as the non-oblique cases; however, a strong downward flow was generated on the particle side. In contrast to the bulk em force the magnitude of the migration force became lower. A small (relative) repulsive force existed between the two particles, which is related to the anti-clockwise rotating forces of the particle pair. The results obtained give valuable insight into the case that takes into account the particle coagulation and transportation in the em processing of metals.
