| Abstract: | The process of jetting Re-Mg powder ac Si-Fe powder are studied in this paper. The results show that the casting a ductile cast iron ingot mould,produed in this process is of many advantages, such as good in nodulizing effect,unform in hardness and high in yield. The average service life of the casting is 115 times, and is 40 times higher than that of the casting produced in normal method. |
