Popis: A research was done to investigate the effect of 0.05…0.25 wt.% addition rate of Ca, Zr, Al – FeSi alloy, in ladle and in-mould inoculation of grey cast irons. In the present paper, the conclusions drawn are based on thermal analysis. For solidification pattern, some specific cooling curves characteristics, such as undercooling degree at the beginning of eutectic solidification and at the end of solidification, as well as recalescence level, were identified to be more influenced by the inoculation technique. In order to secure stable and controlled processes, representative thermal analysis parameters could be used, especially in thin wall grey iron casting production.
