A NEW TECHNIQUE—ELECTROMAGNETIC CENTRIFUGAL CASTING PROCESS

A new technique of centrifugal casting under electromagnetic field was firstly proposedand investigated.Taking a heat resisting alloy steel 25Cr20Ni and an Al-Cu alloyas examples,products,though their length,diameter and wall thickness are varied,re-vealed so superior macrostructures that the mechanical properties are much improved incomparison with conventional centrifugal casting.
