滑靴是采煤机的一个重要零件,铸造质量要求较高,不得有气孔、缩松等铸造缺陷。利用计算机软件V-Cast对滑靴的凝固过程进行了数值模拟,根据模拟结果设计了冒口和浇注系统。结果表明,采用新工艺生产的铸件能消除铸造缺陷,得到了质量合格的铸件。 Slipper is an important part of shearer, casting higher quality requirements, may not have holes, shrinkage and other casting defects. The solidification process of slipper was simulated by computer software V-Cast, and the riser and pouring system were designed according to the simulation results. The results show that the castings produced by the new process can eliminate casting defects and obtain qualified castings.
