用高速锤作叶片挤压工艺设备,进行叶片的叶身型线部份无屑加工试验及试生产,我厂在1969年就开始进行,至今已有20年生产史。先后生产燃机压气机1～5级叶片,船机5～10级压气机动叶片,10万瓩汽轮机2～8级动叶片,20万瓩2～9级动叶片。叶片材料为1Cr13,2Cr13,cr11MoV,Cr17H2等。叶片年产量超万片。 17年来的生产实践证明,叶片内在质量稳定。如1Cr13材料经高速锤挤压成形,余热淬火后回火,其机械性能的各项指标超过技术条件要求指标,几乎全部达到2Cr13(σ=600MPa)要求的各项性能指标。
With high-speed hammer for blade extrusion process equipment, leaves blade line part of the non-chip processing test and trial production, I plant began in 1969, has been 20 years of production history. Has produced a turbine compressor 1 to 5 leaves, ship 5 to 10 compressor blades, 100,000 瓩 turbine 2 to 8 rotor blades, 200,000 瓩 2 to 9 rotor blades. Leaf material 1Cr13, 2Cr13, cr11MoV, Cr17H2 and so on. Annual output of more than 10,000 leaves. 17 years of production practice has proved that the internal quality of leaves stable. Such as 1Cr13 material by high-speed hammer extrusion forming, quenching after tempering, the mechanical properties of the indicators exceeded the technical requirements of indicators, almost all reached 2Cr13 (σ = 600MPa) requirements of the performance indicators.
