过去,我厂的铸铁件(尤其是三角皮带轮、齿轮、平板之类的铸件)由于夹渣而报废的现象比较严重。自从应用圆柱形和锯齿形撇渣口以来,这个问题就基本上得到了解决,废品率显著降低。事实证明,适当的应用撇渣口,是解决铸件渣孔的关键。现将我厂应用这两种撇渣口的体会,简要介绍于后,供大家参考。 In the past, the cast iron parts of our factory (especially castings such as V-belt pulleys, gears and flat plates) were seriously scrapped due to slag inclusions. Since the application of cylindrical and zigzag skimmer mouth, this problem has basically been solved, the rejection rate was significantly reduced. Facts have proved that the appropriate application of skimmer mouth, slag casting hole is to solve the key. Now I plant the application of these two Skimmer mouth experience, a brief introduction in the future, for your reference.
