- 摘要:
- 针对重型燃气轮机燃烧室外壳整体尺寸较大、壁薄、尺寸精度难控制、补缩难度大、探伤要求高等特点，采
用铸件不同方向、选用不同的收缩率、设置防变形拉筋、冒口跨热节补缩、设置冷铁和补贴分区补缩等工艺措施。 通过
Procast 软件分析铸件凝固过程，优化铸造工艺，最终成功生产出合格的铸件。
According to the characteristics of the heavy gas turbine combustion chamber housing such as including large
overall size, thin wall section, high dimension accuracy demand, difficulty in feeding and strict restriction for flaws detected
by nondestructive inspection, the measures including using different shrinkage rules for different direction of the casting,
reinforcement bar to prevent distortion, middle risers to feed two hot spots, and adding pads for helping to feed and chills
are adopted. The casting process was simulated and optimized by Procast software. Finally qualified combustion chamber
housings are successfully produced.
