FIELD: electricity.SUBSTANCE: treated product is installed and insulated electrically at insulators with earthing wire. A bushing is installed at the treated surface of the product with formation of an operating chamber, which bottom is treated surface of the product. Metal beads are placed inside the operating chamber at the product treated surface, motion of beads is activated by simultaneous switching of ultrasound oscillation of waveguide and step-by-step entry of the waveguide to the bushing using operating butt end of the waveguide as a cover of the operating chamber. Current availability in earthing wire is recorded and entry of the waveguide is stopped to the bushing since current appearance. Upon stoppage of the waveguide, when current appears at the product earthing wire, position of the waveguide is recorded and protruded in the preset operating position, and when it is reached surface of the product is treated by beads within the preset time. Then waveguide is returned to the recorded position and surface of the product is treated by beads until current value is reduced at earthing wire in regard to the recorded current value. Then treatment of the product surface by beads is completed and the waveguide is returned to the initial position.EFFECT: improved quality of hardening treatment of metal products surface.1 dwg, 1 tbl, 1 ex |
