The invention discloses a gas-based shaft-furnace direct-reduction smelting method for high-chromium-content vanadium-titanium magnetite. According to the method, a shaft furnace serves as main equipment, and 100% high-chromium-content vanadium-titanium magnetite serves as a raw material. The method is characterized by comprising the steps of preparing oxidized pellets through grinding the magnetite, palletizing, oxidizing and roasting, putting the oxidized pellets in the shaft furnace, carrying out direct reduction by using reducing gas, and then, carrying out smelting separation in a high-frequency induction furnace, thereby obtaining vanadium-chromium contained pig iron and high-titanium-content slag. According to the method disclosed by the invention, the grade and yield of iron in the obtained pig iron are higher than 90%, the yield of both vanadium and chromium is higher than 85%, the grade of TiO2 in the high-titanium-content slag is about 40%, and the yield reaches 85-90%.
