The invention discloses taphole clay for a 5500-M<3> blast furnace. The taphole clay for the blast furnace is characterized by being prepared from, by weight, 10-20 parts of fused alumina zirconia, 6-10 parts of titanium nitride, 8-15 parts of aluminium nitride, 10-20 parts of pyrophyllite rawore, 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 425 portland cement, 3-8 parts of ferro-silicon nitride powder, 2-5 parts of anchracite duff, 3-8 parts of resin powder, 0.01-0.05 part of polyether-modified organopolysiloxane and 15-18 parts of additional binding agents. According to the technical scheme, the taphole clay which is capable of conveniently making mud and resisting molten iron corrosion and stable in molten iron draining is obtained, and the problems, caused by the fact that the quality of existing taphole clay for the blast furnace is poor, that a taphole is shallowed, washing resisting and molten iron corrosion resisting cannot be achieved, and the taphole clay is polluted seriously can be solved.
