放顶煤液压支架齿板的工作条件恶劣,对铸造质量要求较高,不得有气孔、缩松等铸造缺陷。利用计算机模拟软件V-Cast对齿板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。实际生产表明,该工艺能消除齿板的铸造缺陷,并能确保铸件质量合格。 Caving hydraulic support tooth plate bad working conditions, higher requirements on the quality of casting, may not have pores, shrinkage and other casting defects. The solidification process of tooth plate was simulated by computer simulation software V-Cast, and the riser and pouring system were designed according to the simulation results. The actual production shows that the process can eliminate the casting defects of the tooth plate and ensure the quality of the casting.
