摘要：In order to improve strength, toughness, casting quality of the nodular cast iron crankshaft and reduce scrap, liquid eutectic point control, the nodulization process, non-core casting technology, tin - copper alloying and structure uniformity were studied. Using the studying results, high strength and toughness SG iron crankshaft have been successfully produced and shrinkage defect is decreased to O. 19% .
