Yttrium base heavy rare earth, magnesium, barium, calcium, silicon and other elements as yttrium base heavy rare earth compound nodulizing agent main ingredients of this series composite yttrium base heavy rare earth magnesium nodulizing agent, the ratio of magnesium is guarantee that it is the main element of spheroidizing, while heavy rare earth elements has auxiliary spheroidizing effect, it mainly plays a role of deep deoxidization, desulphurization and guarantee to offset the adverse effects of impurities anti-spheroidizing, beneficial to the crystallization of cast iron, promote the formation of a large number of small graphite in cast iron ball fine grained organization, thus increase per unit volume of nodular cast iron graphite count, reduce the hidden trouble of the nodular cast iron formation of shrinkage cavity and slag inclusion defects, reduce the minimum necessary to ensure the graphite spheroidizing residual magnesium content, increase of iron liquid keep spheroidizing effect time (ability to resist spheroidizing recession). Adding barium is to play to the coordination of rare earth elements, magnesium, calcium, barium, reduce the content of rare earth and magnesium, the spheroidizing effect is better, barium as graphitization element with magnesium can reduce the vapor pressure of magnesium under high temperature, improve magnesium absorption rate, increase the per unit volume of nodular cast iron graphite count, improved breeds (secondary graphitization modification) effect, and inhibit the formation of carbides. Calcium is primarily it has strongly promote the graphitizing effect, at the same time, Ca and Mg can form Mg2Ca intermetallic compounds decompose magnesium delay, control of nodularizer in liquid iron absorption and reaction speed. This series of nodularizer has the following characteristics: the ability to resist spheroidizing recession and graphite distortion resistance is strong, low content of magnesium oxide, reasonable density, stable reaction and components uniform..
