目前大量生产的中、小型铸铁件大部分采用粘土砂湿型铸造,为提高生产率,越来越多的工厂采用自动化造型设备造型。造型过程参数选择多半是根据操作者的经验,再通过反复试验决定。虽然最终也能获得质量合格的铸件,但调试阶段往往历时很长,而且由于对多阶段紧实度的 At present, mass production of small and medium-sized cast iron parts are mostly made of clay sand wet casting, in order to improve productivity, more and more factories use automated molding equipment modeling. Modeling process parameters are mostly based on the choice of operator’s experience, and then decided by repeated tests. Although ultimately qualified castings are available, the commissioning phase tends to take a long time and due to the multi-phase compaction
