Cast iron penetration in sand molds, part I: physics of penetration defects and penetration model

摘要

Metal penetration defects account for a relatively large amount of scrapped iron castings. Many of the theories and solutions proposed for prevention of metal penetration defects have been derived from research work on steel castings. The castiron foundry industry has assumed that the fundamental principles for steel penetration defects are equally applicable for cast iron castings. However, this research has conclusively shown that steel and cast iron should be considered separately.
