摘要：Casting fluidity of metals and alloys is of vital importance to foundry men to produce overall soundnessand surface features of the casting.The filling of moulds of intricate casting design, particularly those which include thin casting sections, isusually difficult if the liquid metal has poor fluidity and casting defects such as shortruns or misruns are likely to occur.Actually fluidity of a liquid metal or alloy is a complex characteristics affected by a large number of variables. It isusually controlled by the rate and mode of solidification and the normal method of increasing the fluidity of given alloyin foundry is to increase the casting superheat for the production of premium quality casting with increased mechanicalproperties pouring temperature.The use of such mould coating not only governs the heat transfer rate at the metal mould interface and hencethe length of the metal flow, but it will also affect significantly the cast structures of the casting made.
