Abstract：
The technical parameter difficulties in casting process and smelting process of large ductile iron parts and the selection and control method of technological parameters were described. In 3 500 tons of injection molding machine second plate, Italian ceramic mechanical base for the production and application and verification. The results show that only through reasonable and excellent casting process design and reasonable melting process, con trolling the process control nodes and parameters of each link in the production process, can the large ductile iron parts with qualified mechanical properties and microstructure be produced stably.
