I-Pearlite Heat-resistant 12CR 1movg High Pressure Alloy Tube
I-matrix iyinsimbi engashisi kakhulu enesakhiwo se-pearlite noma i-bainite. Kukhona ikakhulukazi uchungechunge lwe-chromium-molybdenum kanye ne-chromium-molybdenum-vanadium. Kamuva, kuye kwathuthukiswa amazinga ensimbi amaningi (njenge-chromium, i-tungsten, i-molybdenum, i-vanadium, i-titanium, i-boron, njll.), futhi ukuqina kanye nokushisa kwensiza kuye kwanda kancane kancane. Kodwa ngokuvamile inani eliphelele lezinto ezixubayo licishe libe ngu-5%, futhi isakhiwo salo sihlanganisa insimbi ye-bainitic ngaphezu kwe-pearlite. Lolu hlobo lwensimbi lunamandla amahle okushisa aphezulu kanye nokusebenza kwenqubo ku-450 ～ 620 ℃, futhi lunokushisa okuhle, i-coefficient ephansi yokukhulisa kanye nentengo ephansi. Lusetshenziswa kabanzi ukwenza izinto zokwakha ezahlukahlukene ezingashisi ukushisa ezisukela ku-450 ～ 620 ℃. Njengemipayipi yensimbi yebhoyila yeziteshi zikagesi, ama-impeller e-turbine enomusi, ama-rotor, ama-fasteners, imikhumbi enengcindezi ephezulu yokuhluza uwoyela kanye nezimboni zamakhemikhali, ama-boiler okushisa imfucuza, amashubhu esithando sokushisa kanye namashubhu okushintshanisa ukushisa, njll.
[1] Insimbi yamapayipi ensimbi angashisi kakhulu.
Isetshenziswa kakhulu njengezindonga zamanzi ebhoyila, ama-superheater, ama-reheater, ama-economizer, ama-header namapayipi omusi, kanye namashubhu okushintshanisa ukushisa kwamandla kagesi kanye nawenuzi. Izinto ziyadingeka ukuthi zibe nomkhawulo ophezulu wokuqhekeka, amandla ahlala isikhathi eside kanye ne-plasticity ehlala isikhathi eside, ukumelana okuhle kwe-oxidation kanye nokumelana nokugqwala, ukuzinza okwanele kwesakhiwo kanye nokushibilika okuhle kanye nezakhiwo zokucubungula ukushisa nokubanda. Impilo yesevisi eklanyelwe ifinyelela emahoreni angu-200,000. Imikhiqizo eyinhloko eShayina yi-12CrMo, 15CrMo, 12Cr2Mo, 12CrlMoVG amashubhu e-alloy anengcindezi ephezulu, kanye ne-12Cr2MoWVTiB, asetshenziswa ebangeni elingu-480 ～620℃. Ukulungisa nokulungisa ngokuvamile kusetshenziswa ekwelapheni ukushisa.
[2] Insimbi yamapuleti emikhumbi anomfutho ophezulu.
Embonini yamakhemikhali kaphethiloli, igesi yamalahle, iziteshi zamandla enuzi kanye neziteshi zamandla, amapuleti ensimbi angashisi kakhulu asetshenziswa kakhulu ukwenza imikhumbi yokucindezela. Izinhlobo eziyinhloko eShayina amapayipi e-alloy anamandla aphezulu angu-15CrMoG (1.25Cr-O.5Mo), 12Cr2Mo (2.25Cr-1Mo) kanye no-12Cr1MoV, njll. Isibonelo, ama-hydrogenation reactors odonga olushisayo asebenzisa kakhulu amapuleti ensimbi angu-2.25Cr-1Mo) (25 ~ 150mm). ), ngoba imishini ibilokhu isebenza ngaphansi kwezimo zokushisa okuphezulu, ukucindezela okuphezulu kanye nokumelana ne-hydrogen isikhathi eside, ngenkathi kucatshangelwa ukuvimbela ukuqhekeka ku-475°C, izinto ziyadingeka ukuthi zibe nobumsulwa obuphezulu, kanti i-sulfur ne-phosphorus kulindeleke ukuthi zibe ngaphansi kuka-0.01% kanye ne-tin ephansi kakhulu. Izinto eziyingozi ezifana ne-antimony ne-arsenic zidinga ukuncibilikiswa kwesithando sikagesi kanye nokucwengisiswa kwangaphandle.
[3] Insimbi yezibambo.
Insimbi yokubopha iyinto ebalulekile edlala indima ekuxhumeni kwama-turbine omusi, ama-boiler kanye neminye imishini yezitsha ezinomfutho ophezulu. Idinga umkhawulo wesivuno owanele, ukuqina kokuphumula okuphezulu, i-plasticity enhle ehlala isikhathi eside kanye nokuzwela okuncane okuhlala isikhathi eside. Ukumelana ne-oxidation kanye nokusebenza okuhle kokusika. Imikhiqizo eyinhloko eShayina yi-25Cr2Mo, 25Cr2MoV, 25Cr2Mo1V, 20Cr1M01VNbTiB, njll., engasetshenziswa ebangeni elisukela ku-500 ～570℃ ngokulandelana. Lawa mabanga ngokuvamile asetshenziswa ngemva kokucima nokushisa.
[4] Insimbi ye-rotor (i-spindle, impeller).
I-shaft eyinhloko, i-impeller kanye ne-rotor ehlanganisiwe ehlanganisiwe kungenye yezingxenye ezibalulekile ze-turbine yomusi. Izinto ezidingekayo ukuze zibe nezakhiwo ezinhle zomshini eziphelele, ukuqina kokuphuka, ukumelana okuphezulu kokuqhekeka kanye namandla okukhuthazela, kanye nokumelana okuhle kokukhathala kokushisa. Izinhlobo ezivame ukusetshenziswa ze-spindle kanye ne-impeller eShayina yi-35CrMo, 35CrMoV, 27Cr2Mo1V, 12Cr3MoWV, njll. I-rotor ye-turbine yegesi yenziwe ngensimbi engu-20Cr3MoWV. Kusetshenziswa ukwelashwa kokucima nokushisa. Kwezinto ezinkulu ezifana nama-rotor ahlanganisiwe nama-impeller, ukuze kuncibilikiswe ngokuphelele i-vanadium carbide futhi kuthuthukiswe ukuqina nokuqina, ukwelashwa kwangaphambilini kungenziwa ngaphambi kokucima, noma inqubo yokwelapha ukushisa yezindlela ezimbili zokulungisa nokushisa ingasetshenziswa.
[5] Insimbi engu-1Cr5Mo kanye ne-Cr6SiMo.
Lezi zinhlobo ezimbili zinezici zokuhlanganisa eziphakeme kakhulu ensimbini evikela ukushisa ye-pearlitic. Zinokumelana okuhle nokushisa kanye nokumelana nokugqwala kuma-petroleum media. Zisetshenziswa kabanzi ekwakhiweni kwamapayipi nemikhumbi yemishini yokucwilisa uphethiloli, amashubhu okushisa esithando kanye nama-heat Exchangers, njll., asetshenziswa futhi njengezinto zokushisa ezishisayo, amaphampu kaphethiloli, ama-valve, ama-boiler hangers nezinye izingxenye. Ngokuvamile izinga lokushisa lokusetshenziswa lingaphansi kuka-650℃. Njengoba le nsimbi iyinsimbi eqinile emoyeni, umthungo wokushisela unobunzima obukhulu kanye ne-plasticity embi, ngakho-ke kufanele upholiswe kancane kancane futhi ufakwe emanzini ngemva kokushisela.
Ukugoqa okushisayo (ishubhu lensimbi elingenamthungo elikhishwe): ishubhu eliyindilinga i-billet → ukushisa → ukubhoboza → ukugoqa okunemiphetho emithathu, ukugoqa okuqhubekayo noma ukukhishwa kweshubhu → usayizi (noma ukunciphisa) → ukupholisa → ishubhu le-billet → ukuqondisa → ukucindezela kwamanzi Ukuhlolwa (noma ukutholwa kwamaphutha) → uphawu → indawo yokugcina impahla.
Ipayipi lensimbi elingenamthungo elidonswe ngokubandayo (eligoqiwe): ishubhu eliyindilinga i-billet → ukushisa → ukubhoboza → isihloko → ukunamathisela → ukukhahlela → ukugcoba amafutha (i-copper plating) → ukudweba okubandayo okunama-multi-pass (ukugoqa okubandayo) → ishubhu le-billet → ukwelashwa kokushisa → ukuqondisa → Ukuhlolwa komfutho wamanzi (ukutholwa kwamaphutha) → uphawu → indawo yokugcina impahla.
