| Abstract: | Through the introduction of the application of ductile-iron in mould of automobile and the present status of casting technology of ductile-iron mould both domestic and abroad,fatigue mechanism and the feasibility of ductile-iron used in middle-large mould was analyzed.It was pointed out that ductile-iron mould made by expendable pattern casting(EPC) replacing alloy-steel mold in the production of ductile-iron middle-large mould was development direction in order to reducing cost,decreasing manufacture period due to improvement of ductile-iron properties. |
