| Abstract: | Injection innoculation is a new technological method that the innocu-lation reagent of powder grain is injected into iron metl by the carrier of nitrogen. ThispaPer diseribes experimental study of injection innoculation using a injection devicewhich is made by ourselves. The resulte showed that powder injection treatment canimprove the effect of innoculation improve the shape of graphite, fine eutectic cell obvioushg,eliminate chill effectiveIly,and then improve the intensity of cast iron. Injectioninnoculation has become a much more effective technigue of innoculation. |
