In order to solve the problem of moldfilling of walled castings
the moldfilling ability of A357 alloy under the travelling electromagnetic field has been studied experimentally by using large electromagnetic casting equipment in this paper.The results show that the moldfilling ability of thick walled casting has been larger than that of thin walled casting under the same conditions of the travelling electromagnetic field.Meanwhile
the moldfilling ability of the same walled castings with the travelling electromagnetic field has been over 50% larger than that without the field.
