On the basis of numeral modelling of hydrodynamic processes, which are going in melt during elec- trical hydro pulse treatment, the pressure field within a liquid metal during the post discharge stage is calcu- lated. It is shown, that application of waveguide attachments allows promote the pressure levels during the initial treatment stage, increase the part of energy dissipation in melt and extend cavity duration. It is found that treatment efficiency is determined by correlation of geometrical sizes of working element and of geo- metrical sizes of the ladle.
