| Abstract: | The effects of several inoculants and alloy elements on gray cast iron′s properties are investigated.The experiment and production results show that when 60%BaSi+40%SiFe is selected as compound inoculants for gray cast iron′s cylinder block with 3.9%～4.1%CE and alloy elements are added,its tensile strength is higher than HT250 grade and its sensibility of section hardness and white iron width are reduced,thus reaching the plan requirements.At the same time its inoculation mechanism is studied and its inoculated structure is analyzed. |
