Liquid phase may or may not be present on the casting surface during solidification. If present, it may cause various casting surface defects. Based on the Schwartz equation of solidification of metal in mold, an equation of surface temperature of alloy castings poured without superheat is introduced. Wetness index is deduced from the equation with which it can be judged if liquid phase is present or not on the casting surface. An equation is proposed to estimate how much superheat can further be raised until the liquid phase appears on the casting surface. Usefulness of the equation is demonstrated by comparing it with the numerical calculation of a series of iron base alloys and an aluminum alloy. The effects of various thermal parameters, in particular solidification temperature range of alloys, on the wetness of casting surface are discussed.
