The invention discloses 5500 m<3> blast furnace stemming. The 5500 m<3> blast furnace stemming is characterized by being prepared from, by weight, 10-20 parts of fused zirconia alumina, 6-10 parts of titanium nitride, 8-15 parts of aluminum nitride, 10-20 parts of pyrophyllite raw ore, 1-3 parts of zirconium carbonate, 10-20 parts of ball clay, 2-4 parts of alumina powder, 12-20 parts of graphite powder, 0-1 part of silicate 425 cement, 3-8 parts of ferro-silicon nitride powder, 2-5 parts of anthracite culm, 3-8 parts of resin powder, 0.01-0.05 part of polyether modified polysiloxane and 15-18 parts of additional binding agents. After the technical scheme is adopted, the stemming which is convenient to hit, resistant to molten iron erosion and stable in molten iron discharge is obtained, and can solve the problems that because the quality of stemming used for existing blast furnaces is poor, tap holes become shallow, flushing and molten iron erosion can not be resisted, and stemming pollution is severe.
