The heat transfer during the complete cycle (from pouring, to solidification, and to
cooling to room temperature) is another important consideration in metal casting.
Heat flow at different locations in the system is a complex phenomenon and depends
on several factors relating to the material cast and the mold and process parameters.
For instance, in casting thin sections, the metal flow rates must be high enough to
avoid premature chilling and solidification. On the other hand, the flow rate must
not be so high as to cause excessive turbulence-with its detrimental effects on the
casting process.
