| Abstract: | UNS R30006 alloy stator casting which met the needs of the customers was produced by investment casting with casting system improvement. The results show that reasonable improvement of the size and distribution of the gate and readjustment casting system are helpful for the feeding of casting and overflow of gas. As a result， the qualification rate of the casting improves and the utilization ratio of the alloy raises. |
