一种高温合金多联空心涡轮叶片的制备工艺
摘要：
一种高温合金多联空心涡轮叶片的制备工艺，包括：（1）将多联叶片分解成多个叶片单元，制备各单元叶片的叶身蜡模，其中叶身带有陶瓷型芯；带有陶瓷型芯的单元叶身蜡模采用注射成型方式成型，注射温度为63℃-68℃，压力为0.3-0.5MPa,注射时间为10-30秒,保压时间为10-30秒。（2）将各带有陶瓷型芯的单元叶身蜡模放入多联模具中注蜡一次成型，制得多联空心叶片蜡模；（3）多联空心叶片蜡模经涂料、脱蜡、烧结、浇注、清理、脱芯工序，最后得到高温合金多联空心涡轮叶片铸件。
摘要（英）：

The invention relates to a preparation process of a high-temperature alloy multigang hollow turbine blade. The process comprises the following steps of: (1) partitioning the multigang blade into a plurality of blade units and manufacturing a blade body wax mold for each unit blade, wherein a blade body is provided with a ceramic mold core, the unit blade body wax mold with the ceramic mold core is molded in an injection molding way, injection temperature is between 63 and 68 DEG C, the pressure is between 0.3 and 0.5 MPa, the injection time is between 10 and 30 seconds and the pressure is preserved for 10 to 30 seconds; (2) putting each unit blade body wax mold with the ceramic mold core into a multigang mold and injecting wax for primary molding so as to obtain a multigang hollow blade wax mold; and (3) coating, dewaxing, sintering, pouring, clearing and stripping the multigang hollow blade wax mold so as to obtain a high-temperature alloy multigang hollow turbine blade casting.
