| Abstract: | The effect of K/Na-RE modificator on nodular cast iron produced by the recarburation process was investigated. The results indicate that K/Na-RE has an excellent effect on the recarburation process. It can increase molten iron quality and graphite nucleation state remarkably. The graphite nodule amount has an obvious increase, the graphite nodules and the microstructure become fine and homogeneous. |
