Abstract
A method of inoculating magnesium (Mg) on compacted graphite iron (CGI) comprises: providing a partition having a predetermined height on the bottom of a ladle so as to divide the interior of the ladle into a first space and a second space; laminating an Mg inoculant and a cover in order in the second space; and tapping liquid CGI cast iron onto the first space, whereby the Mg inoculant becomes in contact with the liquid CGI iron after the liquid CGI tapped onto the first space goes over the partition toward the second space and after the cover is melted by the liquid CGI. According to the method, the deviation of density of Mg is minimized, and a secondary inoculating process can thus be omitted.
