The invention relates to a method for reducing alkali metal enrichment in a blast furnace. When loads of in-furnace alkali metal oxides are 2.8 to 3.0 kg/t, the blast furnace carries out alkali removing once in each quarter, and the alkali removing period ranges from 15 days to 20 days; in the alkali removing period, the MgO content in slag of the blast furnace is controlled to be 7% to 8%, and the binary basicity of the slag of the blast furnace is controlled not to be larger than 1.15; in the alkali removing period, the temperature of molten iron in the blast furnace is controlled to be 1490 DEG C to 1500 DEG C; the Si content in the molten iron is controlled to be 0.3 percent to 0.35 percent; the Ti content in the molten iron of the blast furnace is controlled to be 0.1 percent to 0.15 percent. The basicity of the slag of the blast furnace is controlled, components and the temperature of the molten iron of the blast furnace are adjusted cooperatively, the discharge rate of the alkali ...
