通过对铸型质量、加砂工艺、造型过程粉化作用以及型砂所受紧实力等情况的研究,认为:气流冲击造型工艺适用于水玻璃石灰石砂造型,所获铸型的紧实度高且均匀、轮廓清晰,可望得到更高的铸件精度和铸件质量. Through the research on the quality of the casting mold, the process of adding sand, the chalking of modeling process and the tightness of the sand, it is concluded that the impact modeling technology is suitable for the modeling of limestone sand of water glass, the compaction degree of the obtained mold is high Uniform, clear outline, is expected to get higher casting accuracy and casting quality.
