Shrinkage and shrinkage ductile iron waste specific phenomenon . Years , casting technology workers a lot of research work on the shrinkage and shrinkage and achieved important results . The review of this article by solidification and shrinkage characteristics of ductile iron castings , to explore changes in the volume of ductile iron solidification process in liquid iron and metallurgical factors , technological factors on the impact of the change in volume ; comprehensive analysis of ductile iron shrinkage cavities and loose formation mechanism and metallurgical factors and technological factors on the formation of shrinkage research ; authors combine their work practices , produced in the laboratory using a special test block , the solidification process of impact test block shrinkage characteristics of process factors and metallurgical factors and come to a certain law ; same time , take advantage of the access to information and research , combined with the actual knuckle Honda Accord Ductile Iron Castings shrinkage defects causes discussed, and the measures of prevention shrinkage , received a certain effect .
