    Nodulizing agent should have strong nodularizing ability when used. Obviously, magnesium is the main component. The boiling point of magnesium is low. The molten iron can be boiled by adding molten iron. The reaction is even up and down. After alloying, the specific gravity increases, and it is not easy to float into the molten iron, reducing the oxidation of magnesium.
