- 摘要:
- 通过体视显微镜和金相显微镜对泥浆泵空气包外壳的缺陷组织进行了分析和探讨并采用三维凝固模拟软
件验证了分析探讨的结果。 采用三维凝固模拟对泥浆泵空气包外壳的铸造工艺进行了优化并制定了两种改进方案。 新
的工艺实现了顺序凝固，消除了缺陷，成功生产出合格铸件并提高了表面质量，验证新工艺方案的有效性。
The defect structures of steel mud pump air chamber casing was analyzed by using stereo microscope and metallographic microscope and also verified by three-dimensional solidification simulation software. The casting process of the air chamber casing was optimized and the two new improved casting processes were made by using the three-dimensional solidification simulation software. The new casting process has achieved sequential cooling, eliminated defects and improved surface quality. Steel air chamber casing castings were successfully produced which verified the effectiveness of the new process.
