Electromagnetic (EM) fields can influence the behavior of liquid metals. EM fields have now been successfully applied to prime commercial scale grade 30 to 80 Ceramic Foam Filters (CFF). The required properties of the EM fields in such a system are different from existing systems. Similar physics are applied, i.e. Lorentz forces induced by time varying EM fields; however, in the present system the forces are used to overcome the metal surface energy for filter priming.This study presents results from 23 inch full scale industrial priming trials, using moderate preheated single to triple 23 inch CFF’s from grade 30 to 80 avoiding thermal shock. The influence on priming of the CFF structure, and the resulting improvements in filter productivity and reliability are discussed. The results obtained utilize Finite Element Modeling (FEM). Estimated filtration efficiency of different filter types are presented as functions of velocity and thickness.
