| Abstract: | In this paper,the influence of the ytirium heavy rare_ear th composite nodulizer on the morphology of graphite,the structure and prope rties of ductile iron has been studied.The results show that this nodulizer has the characters of good desulphurizing ability,good globurizing ability,high fadi ng_resistant of spheroidal graphite,smallizing base structure and enhancing mech anical properties of ductile iron.The properties of the center parts in the heav y section of ductile iron are enhanced when using this nodulizer,such as cool ing wall of blast furnace and heavy section roller. |
