The invention discloses 900 m<3> blast furnace taphole clay. The blast furnace taphole clay is characterized by comprising the following components in parts by weight: 6-10 parts of titanium nitride, 8-15 parts of aluminum 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 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 parts of polyether-modified polyorganosiloxane and 15-18 parts of an additional binder. With the use of the technical scheme, the taphole clay which is convenient to ram, resistant to molten iron erosion and stable in molten iron discharge is obtained, and the problems that a taphole becomes shallow and is free of washing resistance and molten iron erosion resistance, and the taphole clay is seriously polluted due to poor quality of the taphole clay used in a blast furnace at present can be solved.
