Nodulizing ladle cover

The utility model relates to a nodulizing ladle cover. The nodulizing ladle cover is arranged on a nodulizing ladle upper opening in a matching manner, a wire feeding hole is axially formed at the center of the ladle cover, and symmetrical clamping holes are formed on the side surface of the circumference of the ladle cover. According to the nodulizing ladle cover, one wire feeding hole is added on the basis of a traditional ladle cover, nodular cast iron is nodulized in a punching manner instead of a wire feeding manner, and a cored wire is uniformly fed into a casting ladle by setting length and speed by virtue of a wire feeding machine according to amount of molten iron, so that combination of an inoculation wire and a nodulizing wire is realized, and a nodulizing level of the molten iron is guaranteed; the symmetrical clamping holes are formed on the side surface of the circumference of the ladle cover, and the whole ladle cover covers a nodulizing ladle, so that the molten iron can be prevented from spla
