This invention relates to the field of ceramic composite metal casting technology, and discloses a method and apparatus for producing ceramic composite iron-based wear-resistant castings. The production method involves treating ceramic particles with decontamination, coarsening, sensitization, activation, and chemical plating to obtain modified ceramic particles; mixing and stirring the modified ceramic particles and a coating material to obtain a ceramic preform; fully heating the ceramic preform; then removing it and placing it into a mold cavity to obtain a mold; heating the mold in a tank; pouring molten iron after heating; and cooling after casting to obtain the ceramic composite iron-based wear-resistant casting. This invention also discloses a production apparatus for ceramic composite iron-based wear-resistant castings. This invention, employing the above-mentioned method and apparatus for producing ceramic composite iron-based wear-resistant castings, promotes the composite of ceramic and molten metal from a casting process perspective, ensuring that the molten metal can penetrate the fine pores of the ceramic preform, resulting in a good interface bonding between the high-chromium cast iron and ceramic particles, without unbonded or microscopic gaps.
