FIELD: metallurgy, possibly restoration of inner surfaces of crystallizers.
SUBSTANCE: method comprises steps of pumping electrolyte along part axis; applying voltage to anode. Anode is made in the form of sections arranged in lengthwise direction while outer dimensions and length of each section correspond to configuration and wear degree of part inner surface. Voltage is applied to each section of anode; space between surfaces of part and anode is filled with dielectric bodies imparted to oscillating motion due to common angular motions of part and anode.
EFFECT: enlarged assortment of restored parts, mainly non-round cross section parts.
