Abstract: In this paper,the wire feeding method and the conventional method in production of automobile crankshaft is compared,summing up that the wire feeding method has an advantage in the production of iron small part. Compared with the conventional method,the wire feeding method has the advantage,such as less nodulizer added,less temperature drop,less amount of slag produced,residual magnesium content that is easy to control,good spheroidizing effect,stable spheroidization effect,more foundry returns.
Keywords: wire feeding method; automobile crankshaft; spheroidizing; residual magnesium content; small ductile iron pieces
