| Abstract: | By utlizing abundant local resource of ytirium and combining the characteristics of magnesium, barium,calcium and silicon,a sort of composite nodulizer-ytirium-based heavy rare earth nodulizer was developed which is characterized by its good desulphurizing and deoxidizing rate effect,excellent effect to neutralize anti-nodulizing effect of trace elements,strong nodulizng effect and degeneration-resistance,good effect to fine matrix structure,decreased chilling tendency and wide scope of application.Using this nodulizer to produce some important castings such as water-cooled wall of blast furnace and roller could increase mechanical properties of central area and casting yield. |
