The utility model relates to a seating brick of a steel ladle bottom-blowing ventilation brick in the ferrous metallurgy industry, and specifically relates to the seating brick, capable of effectively improving the life, of the steel ladle bottom-blowing ventilation brick. A combination metal anchorage is arranged inside of a refractory material casting body of the seating brick. Thus, the overall combination strength of refractory materials of the ventilation seating brick is improved; the probability that the refractory materials of the seating brick peel off in large pieces and crack during the using process is reduced; and the service life of the ventilation seating brick is prolonged, thereby further improving the service life of the ventilation brick.
