| Abstract: | The characteristics and advantages of cored-wire injection nodularizing,inoculating and modifying-purifying treatment technique were introduced. The effects of using pour-over process and cored-wire injection process for production of QT450-10 grade nodular iron and Cr25 type wear resistant white cast iron were compared. The results showed： （ 1 ）The cored-wire injection process has following advantages：high alloy recovery rate,good result repeatability,saving material,low treating cost,low environmental pollution,low working hardness; （2）when using cored-wire injection process for purifying-modifying treatment, the recovery rate of modifying agent was high and stable that was beneficial to improve casting quality. |
