铸造生产中如何防止工艺性作业时的硅尘飞扬问题,目前仍是一个薄弱环节。虽然部分工厂(车间)已在打箱和清砂过程中推行湿式清砂,但是这种方法尚未能为更多的工厂所采用。究其原因,主要是对湿式清砂的可能性存在着怀疑,认为它会导致铸件产生变形与裂纹,甚至引起机械性能的变化。我们认为:湿式 How to prevent the problem of flying of silicon dust during the process of casting in the casting production is still a weak link. Although some factories (workshops) have implemented wet sand removal during boxing and sand removal, this method has not yet been adopted by more factories. The reason is mainly the possibility of wet sand there is doubt that it will lead to casting deformation and cracks, and even lead to changes in mechanical properties. We think: wet
