| Abstract: | The research results indicated that the gray spots in a crankshaft made of ductile cast iron with pearlite matrix can be efficiently overcome by using the low rear earth spheroidization agent with the antimony,lower content of silicon and a middle content of carbon,decreasing the sulphur content of the iron liquid,and avoiding the disturbance elements in the charge |
