| Abstract: | The lost foam casting process was adopted to produce the Z46-18/4 gray iron machine body,the iron grade wasHT300.As the result of adopting un-pressured gating system,setting chills and internal denseners,strictly controlling chemical composition of iron melt,conducting inoculation two times and kepting the casting in mold for appropriate time after pouring and before knock out,casting inspection showed that the casting had no any defect,the microstructure of the separately cast test bar was consisted of 97% pearlite and 3 carbide,and its tensile strength was of 325 MPa,hardness was of 229 HB. |
