Measures for Preventing the Deformation of Graphite Morphology in Heavy Section Ductile Iron
The effects of the mixed nodulizer,suspension pouring process and the trace element on the graphite morphology were aiscussed in heavy section ductile iron by using the simulating test set.The experiment results show that the mixed nodulizer,suspension pouring process and the trace elements Sn,Sb can prevent the deformation of graphite and can inprove the nodularization grade.
