Hauv cov teb ntawm kev tsim hluav taws xob thermal thiab kev ua cov khoom siv petrochemical, qhov twg qhov kub siab thiab siab siab yog cov qauv, A335 P91 alloy steel yog cov khoom siv tseem ceeb. Nws yog siv dav hauv cov kab hluav taws xob tseem ceeb thiab rov ua kom sov cov ntu kub vim nws lub zog kub zoo heev, kev tiv thaiv nkag, thiab kev tiv thaiv oxidation. Txawm li cas los xij, ib lo lus nug feem ntau tshwm sim thaum lub sijhawm yuav khoom lossis siv: Qhov txawv ntawm Hom 1 thiab Hom 2 yog dab tsi? Tsab xov xwm no muab cov lus piav qhia ntxaws ntxaws.
Qhov Txawv Tseem Ceeb: Cov Txheej Txheem Tsim Khoom & Microstructure
Cov kev cai ntawm cov tshuaj lom neeg sib xyaw rauA335 P91yog txhais los ntawm ASTM A335 tus qauv nws tus kheej. Kev faib tawm ntawm Hom 1 thiab Hom 2 tsis yog los ntawm ASTM A335, tab sis los ntawm lwm tus qauv txhawb nqa tseem ceeb: ASTM A213 (Tus Qauv Txheem rau Seamless Ferritic thiab Austenitic Alloy-Steel rau Boiler, Superheater, thiab Heat-Exchanger Tubes).
Qhov sib txawv tseem ceeb ntawm ob hom no yog nyob rau hauv cov txheej txheem kho cua sov kawg, uas ua rau muaj qhov sib txawv hauv lawv cov qauv me me.
Nws dhau los ntawm Normalizing + Tempering. Cov yeeb nkab raug normalized saum qhov kub austenitizing thiab tom qab ntawd raug rau siab tempering.
Microstructure: Nws ua tiav cov qauv martensite uas tau tempered tag nrho. Qhov no yog qhov classic thiab feem ntau cov xwm txheej rau P91 hlau, muab qhov zoo tshaj plaws kev sib xyaw ua ke ntawm cov khoom siv kho tshuab.
Nws raug annealing Subcritical Annealing. Cov yeeb nkab raug annealed ntawm qhov kub qis dua Ac1 (qhov kub qis dua qhov tseem ceeb).
Microstructure: Nws cov qauv muaj annealed ferrite + carbides. Nws tsis dhau qhov txheej txheem normalizing tag nrho los tsim martensite.
Vim li cas thiaj muaj hom 2?
Cov txheej txheem Hom 2 muaj nyob rau hauv kev ua kom tau raws li qhov kev kam rau siab nruj heev.
Cov txheej txheem Normalizing + Tempering tuaj yeem ua rau me ntsis distortion lossis hloov pauv hauv lub ovality ntawm cov yeeb nkab, uas tuaj yeem ua teeb meem rau cov ntawv thov nrog cov kev xav tau ultra-high precision.
•Kev ua kom sov subcritical yog ua tiav ntawm qhov kub qis dua thiab yog ib qho txheej txheem mos mos, zoo dua khaws cov qauv geometry thiab qhov ntev ntawm cov yeeb nkab tom qab ua haujlwm txias.
Kev Sib Txawv ntawm Kev Ua Tau Zoo & Kev Ceeb Toom Tseem Ceeb
Qhov sib txawv tseem ceeb tshaj plaws yog nyob rau hauv cov khoom siv kho tshuab, tshwj xeeb tshaj yog lub zog kub siab.
•Hom 1 (N&T): Muaj lub zog siab tag nrho thiab lub zog nkag siab siab raws li cov lus qhia txheem. Nws yog qhov zoo tshaj plaws thiab tus qauv rau kev tsim thiab kev siv.
•Hom 2 (Annealed): Nws lub zog qis dua Hom 1. Nws lub zog kub siab thiab cov khoom nkag tsis tuaj yeem ua tau raws li Cov kev cai rau cov khoom siv P91 raws li tus qauv ASTM A335.
Yog li ntawd, cov khoom siv Hom 2 yuav tsum TSIS TXHOB siv ncaj qha rau hauv kev pabcuam kub / siab! Yog tias cov kav dej hauv qhov xwm txheej subcritical annealed (Hom 2) tau txais, tus neeg tsim khoom lossis tus neeg siv kawg YUAV TSUM ua tiav kev kho cua sov normalizing thiab tempering rau lawv ua ntej kev teeb tsa zaum kawg. Qhov no hloov lawv cov microstructure mus rau hauv martensite tempered tag nrho (piv txwv li, hloov nws mus rau Hom 1 mob), yog li ua tiav cov khoom siv kho tshuab xav tau.
Cov Lus Qhia Sib Piv
Hauv cov lus yooj yim, A335 P91 Hom 2 yog ib qho "semi-finished", uas txi txhua yam khoom muaj zog rau kev yooj yim ntawm kev tsim khoom thiab lav qhov ntev. Ntawm qhov tod tes, Hom 1 yog qhov "khoom tiav", muaj txhua yam khoom tsim nyog los tswj hwm qhov kub thiab txias thiab qhov chaw siab.
Thaum lub sijhawm yuav khoom thiab tshuaj xyuas, nws yog ib qho tseem ceeb kom qhia meej tias koj xav tau yam twg thiab txheeb xyuas cov ntaub ntawv kho cua sov ntawm daim ntawv pov thawj khoom siv. Kev xyuas kom meej tias cov kav dej uas tau teeb tsa muaj cov qauv me me thiab cov khoom zoo yog qhov tseem ceeb rau kev lav phib xaub kev ua haujlwm zoo thiab txhim khu kev qha ntawm cov chaw tsim hluav taws xob thiab cov chaw lag luam.
