The invention discloses a method for extracting vanadium by using a converter. The method comprises the step of adding vanadium-containing molten iron to the converter so as to extract the vanadium by using the converter and is characterized in that a carburant is added to the vanadium-containing molten iron in a process of extracting the vanadium by using the converter, and the rate of temperature increase of the vanadium-containing molten iron is 10-30 DEG C/min. The method for extracting the vanadium by using the converter has the advantages that under the condition of basically ensuring the rate of vanadium extraction, the temperature of semi-steel obtained after the vanadium is extracted by using the converter can be increased by 5-15 DEG C, and the content of C in the semi-steel is increased by 0.1-0.28 percentage by weight. The method for extracting the vanadium by using the converter can be widely applied to the industrial production.
