Abstract:Aimed at high nodularity of marine diesel engine block, analysis was carried out on how to improve the nodularity from the aspects of material, spheroidization, inoculation, as well as nodularity fading of nodular cast iron. It is pointed out that nodular cast iron has complex production process and every procedure should follow the operation rules to ensure the quality of casting. |
