【Abstract】 During experimental and productional tests different addition of inoculation agent has effect on section- sensitivity of sidelong surface and mechanical properties. With opotimum addition of the inoculation agent the section sensitivity of sidelong surface of gray cast iron can be improved. Furthermore improving techenique and selection material can control the casting defection resulted from the descent of carbon-equivalent so the casting quality can be improved comprehensively.更多还原
