Analysis of Cooling Curves of Nodular Cast Iron

Abstract

The solidification of cast iron is a complex process with characterized entrance and marginal conditions. Thermal analysis is one of the processes that allows us to observe the solidification of alloys. There is a possibility of gaining information about the melted cast iron quality and predicting the final properties of the cast by evaluating the scanned cooling curves by solidification (stable and metastable system). This article deals with the study and analysis of cooling curves taken from production conditions of a foundry during ductile cast iron production. The aim is to discover the reproduction and reliability of the thermal analysis results of cast iron. The study of the progress of the cooling curves and their first derivation to follow the reactions of the curves to changing factors in the production process.

Novel Measurement Method to Study Thermal Aspects of Molding Mixture Decomposition

“…Thermal analysis in the form of recording and interpreting temperature variations of a cooled or heated material over time is widely used today in foundry technology [1]. The broad areas of application mainly cover works based on cooling curve analyses of both non-ferrous and ferrous alloys [2][3][4]. Recently, studies applying traditional methods such as TG-DSC-DTG have been conducted to examine materials that are applicable as bonding agents in foundry purpose mold and core-making technologies [5].…”
