我厂制造的产品,大多数是由铸铁铸成的气缸、曲轴箱、机座等,特别是气缸件,隔层多,形状复杂。在粗加工时,观察不清,待粗加工后,有的砂眼用肉眼可观查出来,有的通过水压试验,发现漏水。其中有的水流成细线状,有的几秒钟渗出一点水珠,有的则成小片渗水珠或多孔渗水等。根据上述情况,我厂曾试用价格很贵的铸508,

I plant products, mostly cast iron castings from the cylinder, crankcase, machine base, etc., especially the cylinder parts, more compartments, complex shapes. In the roughing, the observation is not clear, to be rough, some trachoma visible with the naked eye, and some through water pressure test, found that leakage. Some of them flow into fine lines, some dribble a few drops of water, and others into small pieces of water seepage or porous water seepage. According to the above situation, our factory has tried the expensive cast 508,
