Abstract：The development of long-life and lightweight ingot moulds has become the key to automated mechanical casting in ferrosilicon companies. The ceramic surface layer of iron-based composites, which has the dual advantages of metal and ceramic, is an effective way to prolong the life of ferrosilicon ingot moulds and achieve light weight. In this paper, an overview of feasible industrial preparation processes for ceramic particle-reinforced iron matrix composites and their properties is presented. Several important ceramic particle reinforcements are described and principles for the selection are also given. Based on the excellent resistance to melt damage exhibited by ceramic/grey cast iron composite ingot moulds in the casting of ferrosilicon liquids, this paper outlines the preparation methods and proposes future research priorities.
