摘要
介绍了钛及钛合金的铸造工艺特点及某型号钛叶轮的铸造工艺方法。分析了该型号钛叶轮铸造气孔缺陷产生的原因。采取控制原材料质量、控制涂料和干燥过程以及开设排气孔等工艺措施使钛叶轮铸件内气孔缺陷显著减少。
The characteristics of the casting process for titanium and titanium alloy castings and the casting process for titanium impeller were introduced. The forming reasons for gas cavity defects in titanium impeller castings were analysed. The quantity and size of gas cavity defects can be decreased when adopting process measures, such as controlling quality of raw materials, controlling coating and its drying process, adding exhaust hole in the mould, and so on.
