The calculation of pressure on the wave-guide butt-end and spectrum analysis of acoustical signal, which are generated by a single discharge during electrical hydro pulse treatment of melt, are presented for three strong—willed regimes of energetical excretion. Suitable dependences for practical using which enable to choose the electrical discharge regime are obtained. It is shown, that the highest pressure levels in melt and the widest acoustical spectrum are generated by means of vibratory discharge regime, that enables to treat melt effectively and to influence on its various structural levels.
