Abstract：Ceramic sand,originally developed in China,is a kind of artificial foundry sand with superior properties such as spherical grain shape,high refractory,chemical inertness and good crushing resistance.Since the beginning of 21st century,ceramic sand,in virtue of its exceptional characteristics in foundry use,has been successfully employed in many factories of sand casting(green sand,sodium-silicate bonded sand,no-bake,hot-box,and cold-box,for sand moulding and core-making)and EPC process to produce iron,steel and Non-Ferrous castings.Foundries have gained enormous benefits of binder consumption savings,casting defects reduction,wastes emissions elimination,and quality promotion.By statistics,the largest market of ceramic sand is the engine casting industry.This article introduces several application samples of ceramic sand in production of engine casting parts,such as cylinder blocks,cylinder heads,and exhausting manifolds,as well as turbocharger housings.Some application parameters,for example,ceramic sand grain size distribution,binder adding rate,core sand properties and sand cycling process guidelines are described.Castings components production achievements and sand using principles are also provided.
