The invention belongs to the technical field of metallurgy, and relates to a method for pre-desulfurizing and directly tapping molten iron in a high-speed rail steel smelting process, which comprises the following steps of: after the molten iron is desulfurized and starts blowing, measuring the temperature of the molten iron on line and calculating the actual consumption proportion of magnesium powder and lime before the blowing is finished according to an existing secondary model; according to the deviation condition of the molten iron temperature, the actual consumption ratio of the magnesium powder and the lime and the calculated value of the secondary model, the adding types and the adding amount of the magnesium powder and the lime are controlled, and then the hitting of the molten iron end point S content is guaranteed by controlling the bottom blowing gas flow. According to the method, tapping can be conducted at the desulfurization blowing end point, reblowing is not needed, the ...
