Zusammenfassung:The invention relates to a methodology based on thermal analyisis to determine the carbon equivalent content of a cast iron alloy which comprises the steps of pouring a first sample in a composition cup and a second sample in a thermal cup, obtain both solidification curves, and as a function of the liquidus temperature and the eutectic minimum temperature for both curves, determine if the model to apply is a linear model for hypoeutectic and eutectic zones or a linear model for hypereutectic zone. It also related to an equipment for carrying out said method.
