摘　　要：通过合金元素的加入和合理的熔炼工艺,改变了铸件的组织,减少了夹杂,排气端座的综合性能得到提升,力学性能达到抗拉强度≥276 MPa,抗弯应力≥11.56 k N/cm^2。满足了双螺杆压缩机排气座铸件的技术要求。By adding alloying element and using reasonable smelting process to change the microstructure of the castings and reduce the inclusion in the castings, the mechanical properties of exhaust side seats were significantly improved, the tensile strength ≥276 MPa, flexural stress ≥11.56 k N/cm^2, deflection ≤6.9 mm. The produced twin-screw compressor castings can meet the technical requirements of exhaust seat castings
