The invention relates to the field of furnace maintenance and discloses a method for improving the furnace maintenance efficiency of a blast furnace. The method comprises the following steps: conveying three furnace charges sintered ores, pellets and lump ores to the blast furnace, respectively, wherein the content of titanium dioxide (TiO2) in the sintered ores is 0.2%-0.4%, and the content of TiO2 in the pellets is 0.4%-1.0%; reacting the three furnace charges in the blast furnace to generate liquid iron, wherein the total content of TiO2 of the three furnace charges is 6-7kg/t, and one part of TiO2 of the three furnace charges is turned into titanium (Ti) by use of a reduction reaction and then goes into the liquid iron so that the content of Ti in the liquid iron is increased to the range of 0.1%-0.2%. The method is realized by adding titanium powder to the sintering and pelleting steps; compared with the traditional furnace maintenance by adding titanium in such a manner of purchasing lump ores or titanium-containing pellets, the method has the advantages that the content of Ti going into the liquid iron can be increased while the cost of an enterprise on purchasing high-price titanium-containing resources is remarkably reduced, so that the furnace maintenance efficiency of the blast furnace is improved.
