铸钢件和铸铁件的清理,特别在单件小批生产的重机厂中,迄今仍是一种劳动量很大、机械化程度很低的工序。在最近十年内,铸件清理所用过的方法,基本上是广泛使用手工劳动。这些工作的机械化主要依靠于采用机械化程度较高、并能防止工人受有害物质影响的专业化铸件清理设备,但这在单件生产中是一个十分复杂的问题。因此,在铸件的清理和修整中仍然继续使用着水流参数较低的水力清砂和 The clean-up of steel castings and cast iron parts, especially in the heavy machinery factory in the single-piece, small-batch production, has so far remained a labor-intensive and mechanized process. In the last ten years, the methods used for the cleaning of castings have basically been the extensive use of manual labor. The mechanization of these jobs relies primarily on the use of specialized casting cleaning equipment that is more mechanized and protects workers from harmful substances, but this is a very complex issue in single-piece production. Therefore, in the casting cleaning and finishing still continue to use the water flow parameters lower hydraulic sand and
