Sinchuk A. Improving cast metal quality by means of electrical hydro pulse treatment of melt

The dissertation is dedicated to studying the processes proceeding within the melt under pulse force loading, to determining the technological factors, which are provided improving workability of casting, and to expanding on this basis the functional potentialities of electrical hydro pulse treatment method for increasing cast metal quality. Theoretical and experimental investigation of cavitation disturbing within the melt is fulfilled, influence of electrical discharge regimes and technological electrical hydro pulse factors on quality of aluminum, lead and carbon iron alloys is studied, the mechanism of electrical hydro pulse influence on thermodynamic melt state is formulated. The proposed technical decision enables to increase the treatment efficiency at the expense of using the vibratory discharge regime, optimal energetic parameters and geometrical guide parameters, decreasing time expenditures.
