The invention discloses an electricity conducting heating method for an electrical steel annealed wire and a heating cycle system thereof. The method comprises the following steps: S1, filling an annealing furnace with fused salt heated to be in a liquid state; and S2, separately arranging electrodes impregnated in the liquid fused salt at the steel strip inlet and the steel strip outlet of the annealing furnace, wherein the two electrodes heat electrical steel by means of an electric heating circuit formed by connecting a wire and a power supply. A resistor of the electrical steel is heated to form a loop by means of conductivity of the fused salt, and the fused salt liquid is in good direct contact with the steel strip, so that the contact resistance is low and the current is uniformly distributed on the cross section of the electrical steel strip, and therefore, the temperature of the heated steel strip is uniform under a high speed electric heating condition, and a high annealing temperature can be achieved.
