The invention discloses a preparation method of a porous netty ceramic reinforced steel and iron base composite lining plate. After mixing of TiB2+Ti(C, N) powder and additives, de-ionized water is added for fully stirring to prepare ceramic pulp suspension; organic foam bodies are dipped in ceramic pulp; then, the dipped organic foam bodies are dried; porous netty TiB2+Ti(C, N) precast bodies areobtained after high-temperature sintering; finally, steel and iron matrix material metal liquid is cast in the prepared porous netty TiB2+Ti(C, N) precast bodies by adopting a casting permeation process; and the porous netty ceramic reinforced steel and iron base composite lining plate is obtained after cooling and demolding. The friction coefficient of the composite lining plate prepared throughthe method is improved; reinforcement phases are uniformly distributed in a basal body; the strength and the toughness are improved; and the service life is prolonged.
