Titanium-containing stemming for blast furnace and preparation method thereof

The invention provides titanium-containing stemming for a blast furnace and a preparation method thereof and belongs to the field of metallurgy. The titanium-containing stemming comprises the following components in parts by weight: 8-15 parts of clay, 3-5 parts of kyanite, 1-5 parts of high-temperature asphalt, 10-20 parts of coke granules, 5-10 parts of ferrosilicon nitride, 10-16 parts of silicon carbide, 30-50 parts of high-aluminum homogenized material, 10-13 parts of modified coal tar, 3-6 parts of sericite powder and 5-15 parts of titanium dioxide. The titanium dioxide in the inventioncan react with carbon and the like in a high-temperature reducing atmosphere around an iron outlet in a blast furnace to generate high-melting-point TiN, TiC and Ti (N, C) solid solutions, which are adhered to the damaged part of a lining of the furnace; and a mud drum is formed on the inner side of the furnace wall of the tapping hole, so that the effects of protecting and repairing the furnace wall and the furnace botto
