摘要

Method for determining the tendency to shrink from a spheroidal graphite casting. This invention relates to a method for accurately measuring the micro-squeeze tendency of a spheroidal graphite casting. The procedure is based on the analysis of the metal cooling curves obtained in the liquid-solid transition process. From these curves, the necessary parameters are obtained to accurately measure the micro-squeeze tendency of the aforementioned smelting, among which are the chemical composition, the degree of spheroidization and the size of the spheroids of the graphitic smelting. The object of the present invention is to extend the application of thermal analysis to a completely novel way to know the tendency to microremove a molten metal through the application of energy balances.
