35CrMo ingxubevange yamapayipi ensimbi umakhi indawo yokuthengisa iwaranti
I-35CrMo inombolo ecacisiwe yensimbi yesakhiwo se-alloy (i-alloy quenched and tempered steel), esetshenziselwa ikakhulukazi ukukhiqiza izingxenye ezibalulekile emishinini ehlukahlukene enomthelela, ukugoba kanye ne-torsion nomthwalo ophezulu. Ikhodi yedijithali ehlanganisiwe ye-35CrMo ingxubevange yensimbi yesakhiwo (ingxubevange ecinyiwe nensimbi eshisayo) i-a30352, futhi izinga eliphezulu yi-GB / t3077-2015

Isetshenziselwa ukukhiqiza izingxenye ezibalulekile emishinini ehlukahlukene enomthelela, ukugoba kanye ne-torsion nomthwalo ophezulu, njengegiya le-herringbone, i-crankshaft, induku yesando, induku yokuxhuma kanye nezinsimbi zokugaya insimbi, i-axle enkulu kanye ne-axle yenjini ye-steam turbine, ukuhanjiswa kwenjini. izingxenye, i-motor shaft enkulu, i-perforator emishinini ye-petroleum, amabhawodi obhayela anezinga lokushisa elisebenzayo elingaphansi kuka-400 ℃, amantongomane anezinga lokushisa elingaphansi kuka-510 ℃, ipayipi eliwugqinsi elingenamthungo (izinga lokushisa 450 ~ 500 ℃, alinandawo elimazayo) emishinini yamakhemikhali. ; Ingakwazi futhi ukufaka esikhundleni se-40crni yokukhiqiza shaft yokudlulisa umthwalo ophezulu, i-rotor ye-steam turbine injini, igiya lesigaba esikhulu, i-shaft yokusekela (ububanzi obungaphansi kuka-500mm), njll; Imishini yokucubungula izinto, amapayipi, izinto zokushisela, njll.
Isetshenziswa njengezingxenye ezibalulekile zesakhiwo ezisebenza ngaphansi komthwalo omkhulu, njengezingxenye zokudlulisela zezimoto nezinjini; I-Rotor, i-main shaft, i-shaft yokudlulisa umthwalo osindayo kanye nezingxenye ezinkulu zezingxenye ze-steam turbine generator.
