WebPrediction of Solidification Time: Chvorinov's Rule. The amount of heat that must be removed from a casting to cause it to solidify is directly proportional to the amount of superheating and the amount of metal in the casting, or the casting volume. Conversely, the ability to remove heat from a casting is directly related to the amount of exposed … Webchill casting noun Love words?
