:阐述了采用挂砂冷铁与风冷相结合的强冷工艺。通过计算铸件的热量导出及生产验证 ,证明该工艺是合理的 ;采取 1种长效球化剂延缓球化衰退。
: Describes the use of sand linked cold iron and air-cooled combination of strong cold process. By calculating the calorific value of the castings and the production verification, the process is proved to be reasonable. One kind of long-acting nodulizer is used to delay the degeneration of spheroidization.
