摘要（英）：

The invention discloses high-conductivity steel for an anode rigid claw and a preparation method of the steel, and belongs to the technical field of low-alloy steel. Trace alloy elements are added, the total quantity and proportion of the alloy elements are controlled, a proper preparation technology is used fro controlling a reasonable structure composition and grain size, and the steel materialwith good conductivity and mechanical property and structural function integration and for the anode rigid claw is obtained. The steel comprises, by weight, 0.01-0.1% of C, 0.01-0.5% of Si, 0.01-1.0%of Mn, 0-0.01% of S, 0-0.02% of P, 0.01-0.5% of Al, 0.01-0.2% of V, 0.004-0.02% of N and the balance Fe and inevitable impurities. C, Si, Mn, P, S, Al, V and N simultaneously meet the requirements that the content sum of C, Si, Mn, P, S, Al, V and N is larger than or equal to 0.35%, V/(C+N) is larger than or equal to 0.45 and smaller than or equal to 5.8, V/Al is larger than or equal to 0.25 and smaller than or equal to 1.2, the content of ferritic structures in the steel is not lower than 90%, the content of pearlitic structures is not higher than 10%, and the average grain size of the steelis larger than or equal to 20 micron and smaller than or equal to 200 micron . The high-conductivity steel for the anode rigid claw can be used for the anode rigid claw in electrolytic aluminum.
