Abstract: Lub A106GRB kub-nthuav hlau yeeb nkab, ua ib qho tseem ceeb hauv kev lag luam seamless hlau yeeb nkab, ua lub luag haujlwm tseem ceeb hauv cov kav dej hauv qab qhov kub thiab txias siab vim nws cov txheej txheem tsim khoom tshwj xeeb thiab kev ua tau zoo heev. Tsab xov xwm no piav qhia txog cov txheej txheem tsim khoom, cov yam ntxwv tseem ceeb, cov teb thov tseem ceeb, thiab cov txiaj ntsig tseem ceeb ntawmA106GRBcov yeeb nkab kub-nthuav dav piv rau cov txheej txheem tsim khoom ib txwm muaj, muab cov ntaub ntawv siv rau kev xaiv thiab tsim qauv engineering.

1. Cov Txuj Ci Tseem Ceeb: Kev Txheeb Xyuas Txog Cov Txheej Txheem Kub Nthuav Dav

Cov txheej txheem nthuav dav kub yog ib qho thev naus laus zis ua tiav raws li kev tsim cov yeeb nkab hlau tsis muaj seamless. Nws lub hauv paus suav nrog kev coj cov yeeb nkab hlau tsis muaj seamless me dua (cov yeeb nkab niam) tsim los ntawm kev dov kub lossis kos txias, ua kom sov nws mus rau qhov kub austenitizing nyob rau hauv qhov kub siab tswj tau zoo siv cov cua sov induction nruab nrab zaus lossis lub cub tawg beam. Tom qab ntawd, kev nthuav dav radial yog ua tiav los ntawm lub mandrel nthuav dav sab hauv (xws li lub conical plug) kom thaum kawg tau txais cov yeeb nkab hlau loj dua xav tau.

Tus yuam sij rau cov txheej txheem no yog nyob rau hauv kev tswj qhov kub thiab txias kom raug thiab kev tswj hwm kev hloov pauv, kom ntseeg tau tias cov hlau ntws zoo ib yam thiab cov qauv metallographic ruaj khov lossis zoo tshaj plaws (feem ntau yog ferrite + pearlite rau Qib B hlau) thaum lub sijhawm nthuav dav, yog li lav tias cov khoom siv kho tshuab ntawm cov khoom kawg ua tau raws li lossis tshaj qhov yuav tsum tau ua tus qauv.

2. Cov Yam Ntxwv Tseem Ceeb ntawm A106GRB Cov Yeeb Nkab Kub-Nthuav Dav

Cov yeeb nkab A106GRB kub-nthuav dav ua raws liASTM A106tus qauv, qhov twg "GR.B" qhia tias nws cov khoom qib yog B. Nws cov yam ntxwv tseem ceeb yog:

1. Cov Khoom Siv Kho Tshuab Zoo Kawg Nkaus: Tom qab kub nthuav dav thiab kev kho mob tom qab, cov yeeb nkab yuav tsum ua tau raws li cov kev cai ntawm ASTM A106 GR.B, nrog rau cov nqi ib txwm muaj zog tensile≥415 MPa thiab lub zog tawm los≥240 MPa, ua ke lub zog zoo nrog qee yam plasticity.

2. Kev Tiv Thaiv Kub thiab Siab: Tsim tshwj xeeb rau kev pabcuam kub thiab siab. Nws tswj tau lub zog siab ntawm qhov kub siab (piv txwv li, txog li kwv yees li 450°C), ua rau nws tsim nyog rau kev xa cov xov xwm xws li cov pa thiab cov roj / roj kub siab.

3. Kev Ywj Pheej Zoo thiab Kev Siv Nyiaj Txiag Zoo: Cov txheej txheem nthuav dav kub tuaj yeem tsim ntau yam kav dej loj dua los ntawm tib lub yeeb nkab niam, hla dhau qhov txwv ntawm cov yeeb nkab loj seamless. Nws pheej yig dua thiab yoog tau rau kev tsim cov kav dej loj, phab ntsa tuab piv rau cov kav dej loj seamless dov kub ncaj qha, kuj tseem luv lub sijhawm xa khoom.

4. Tswj Xyuas Qhov Tsis Sib Txuas: Txawm hais tias muaj kev ua tiav theem ob, cov yeeb nkab tiav lawm tseem tsis sib txuas tag nrho, zam cov teeb meem tsis muaj zog uas cuam tshuam nrog kev vuam, ua rau muaj kev sib txuas zoo.

3. Cov Ntawv Thov Tseem Ceeb

Siv cov yam ntxwv saum toj no, A106GRB cov kav dej kub-nthuav dav tau siv dav hauv:

•Cov Txheej Txheem Boiler Rau Lub Hoobkas Fais Fab: Rau cov ntu kub thiab siab ntawm cov kav dej loj thiab rov ua kom cov kav dej kub.

•Kev Lag Luam Petrochemical: Cov kav dej kub hauv cov chaw ua roj, cov nroj tsuag tshuaj, cov kav dej pyrolysis rauv, thiab lwm yam.

•Cov Txheej Txheem Cua Sov: Cov kab tseem ceeb rau kev xa dej kub kub hauv cov txheej txheem cua sov hauv cheeb tsam.

•Kev Kis Roj thiab Roj Av: Qee cov kav dej kis mus deb hauv qab qhov kub siab.

•Lwm Cov Chaw Lag Luam: Ntau yam khoom siv lag luam txuas cov kav dej uas xav tau kev tiv taus kub thiab siab.

4. Kev Txheeb Xyuas Cov Txiaj Ntsig Tseem Ceeb

Piv rau cov kav dej longitudinal seam welded lossis cov kav dej seamless ntawm cov lus qhia tshwj xeeb, qhov zoo ntawm A106GRB cov kav dej kub-nthuav dav yog:

•Kev Sib Npaug "Loj Txoj Kab uas hla" thiab "Tsis Muaj Qhov Txuas": Muab kev daws teeb meem txhim khu kev qha rau cov kav dej loj txoj kab uas hla tsis muaj qhov txuas.

•Kev Ua Raws Cai, Kev Tswj Xyuas Zoo: Cov txheej txheem kho cua sov laus ua kom cov khoom siv kho tshuab thiab microstructure ua tau raws li lossis tshaj qhov yuav tsum tau ua tus qauv.

•Kev Siv Nyiaj Zoo Tshaj Plaws: Siv nyiaj ntau dua thiab yoog tau yooj yim dua rau cov qhov loj me tshwj xeeb piv rau cov kav dej loj uas tsis muaj qhov sib txuas uas kub tag nrho ntawm tib qho kev qhia.

•Peev Xwm Siab thiab Kev Nyab Xeeb: Cov qauv tsis muaj qhov sib txuas ua ke zam kev vuam ntev, muab kev sib npaug ntau dua nyob rau hauv kev ntxhov siab ncig, tsim nyog rau cov xwm txheej nyuaj.

Cov yeeb nkab A106GRB kub-nthuav dav yog ib qho kev ua tiav tseem ceeb hauv kev tsim cov yeeb nkab hlau niaj hnub. Nws ua tau zoo rau kev thov kev lag luam dhau qhov txwv siab tshaj plaws ntawm cov qauv yeeb nkab kub-dov seamless thaum tswj hwm kev nyab xeeb thiab kev ntseeg siab ntawm cov yeeb nkab seamless. Hauv kev tsim cov lag luam tseem ceeb rau lub teb chaws kev lag luam, xws li fais fab thiab petrochemicals, kev xaiv cov yeeb nkab kub-nthuav dav A106GRB kom raug uas ua raws li cov qauv yog qhov tseem ceeb heev rau kev ua kom muaj kev nyab xeeb, ruaj khov, thiab kev lag luam ntev ntawm cov kav dej. Thaum lub sijhawm xaiv, cov txheej txheem tsim nyog ntawm cov chaw tsim khoom, cov txheej txheem tswj xyuas zoo, thiab cov ntawv tshaj tawm tshuaj xyuas khoom yuav tsum tau tshuaj xyuas nruj me ntsis kom ntseeg tau tias ua raws li ASTM A106 cov qauv.
