With the help of finite element simulation software ProCAST,the centrifugal casting process of the working layer of high nickel-chromium infinitely chilled ductile iron rolls was modeled in sections,and the temperature field and flow field of the casting were calculated.The results show that after the molten iron comes into contact with the inner wall of the centrifugal mold,it moves in a circular motion along the inner wall of the mold in a layered form by the combined force of gravity,centrifugal force and friction brought by the rotating mold,and moves to both ends of the mold along the inner wall at the same time,first reaching one end of the mold close to the sprue,and spreading along the axial di-rection to the other end.The high nickel-chromium infinitely cooled ductile iron centrifugal composite roll produced with the assistance of finite element simulation has a dendritic crystal structure in the working layer,and the technical indicators meet the requirements.
