Abstract：
The lost foam casting process of motor end cover with low temperature and high toughness ductile iron was introduced. Low-temperature nodular iron motor end cover shape was processed by EPS plate, the density of EPS plate is18 g/dm^3, and deformation was controlled by key technologies such as foam shape coating, drying and packing molding.The raw materials, chemical composition selection, spheroidization treatment and inoculation treatment of low temperature ductile iron produced by lost foam casting process were analyzed. The results show that the mechanical properties and materials of motor end cover casting of lost foam casting process with low temperature and high toughness ductile iron have reached the advanced technical level of similar products. Motor end cover low temperature high toughness ductile iron has nice surface quality, no slag, sand, cold insulation, deformation and other defects, and it can be mass production.
