Solidification process in casting
WebA thorough understanding of the mechanism of solidification, the rate of heat loss from the material to the mould etc. is essential to predict, how the casting will solidify and thus avoid casting defects like seams, gas porosity, hot tears etc. Since, solidification requires energy to produce a crystalline structure, some super cooling (cooling below the freezing point) is … WebSolidification, process modeling, and filling and feeding concepts are updated to reflect the continuing improvements in casting methods and processing. The major methods of green-sand, no-bake, and shell molding are described further in individual articles.
