FIELD: machine engineering, namely trimming slabs and blooms.
SUBSTANCE: method is realized on base of combined electric, physical and mechanical action upon trimmed product by means of rotating electrically conducting brush-electrode. Method comprises steps of approaching brush-electrode until it touches surface of heated product; equalizing temperature in periphery of brush-electrode and on surface of product according to value 500-600 C; feeding to working zone gas-liquid medium; applying voltage 5 -15 V; setting value for pressing brush-electrode to blank by depth equal to 0.2 -2.0 mm; moving brush-electrode along trimming zone at rate 5 -10m/min.
EFFECT: enhanced efficiency, improved accuracy of trimming.
