A great deal of research work has been done on the spheroidization of rare earth in China. It is found that it is difficult for the common nodular cast iron composition (c3.6-3.8wt%, si2.0-2.5wt%) to obtain the same complete and uniform spheroidal graphite as that of the magnesium nodular cast iron. Moreover, when the amount of rare earth is too high, various abnormal graphite will appear and the tendency of white mouth will increase. However, if it is hypereutectic with high carbon content When the composition (c > 4.0wt%) and the residual amount of rare earth are 0.12-0.15wt%, good spheroidal graphite can be obtained.
