Txawm hais tias steel qauv tau siv dav hauv ntau thaj chaw los ntawm kev tsim txiaj ntawm nws tus kheej kom zoo, nws yog qhov tseeb vim tias qhov kev siv ntau zuj zus uas tib neeg pib saib xyuas qhov zoo ntawm cov khoom. Tus yuam sij rau tib cov khoom lag luam uas yuav tsis muaj teeb meem thaum lawv siv yog qhov ua tau zoo. Txawm li cas los xij, lub ntsiab tseem ceeb rau cov khoom zoo yog ua, yog li nws yuav tsum tshwj xeeb tshaj yog thaum ua. Ua tib zoo saib xyuas kom ntseeg tau zoo ntawm txhua tus neeg tuaj yeem lees paub los ntawm txhua tus. Thaum ua khoom lag luam, cov ntsiab lus tswj nram qab no yuav tsum tau them sai sai rau.
I. Kos duab kom tob
1. Cov duab kos kom ntxaws yuav tsum txhim kho cov qauv thiab cov qauv ntawm cov qauv hlau ua haujlwm raws li cov qauv duab tsim. Cov ntawv no txheeb xyuas lub vuam deformation thiab cov kev ntxhov siab deformation ntawm tus qauv, thiab tso rau pem hauv ntej kev kho mob rau qhov ua ntej deformation ntawm tus qauv.
2. Qhia kom paub tus lej, txoj haujlwm tso tus lej, qhov hnyav, cov khoom siv thiab lwm yam ntaub ntawv ntawm feem. Nws yuav tsum muaj kev cuam tshuam tag nrho peb qhov kev sib raug zoo ntawm txoj haujlwm, lub ntsiab tswj kev tswj hwm thiab lwm cov ntaub ntawv loj, kom thiaj li pab txhawb qhov ntsuas thiab tswj thaum lub sijhawm teeb tsa.
3. ntu raws li lub xaib qhov chaw yuav tsum tau ua, thiab ua tib zoo xav txog qhov sib txawv ntawm kev teeb tsa, weld shrinkage deformation thiab lwm yam, thiab sim weld cov haujlwm uas xav tau welded rau ntawm qhov chaw hauv cov chaw ua khoom, xws li kab hlau rhuav phab ntsa kos rau qhov chaw, kev ua haujlwm platform.
II. Kev tswj cov khoom nyoos
1. Cov hlau: daim ntawv pov thawj zoo lossis daim ntawv tshaj tawm los ntawm cov hlau cog yuav tsum tshawb xyuas txhua yam, thiab tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv cav thiab lwm yam zoo yuav tsum ua tau raws li cov qauv kev cai hauv tebchaws tam sim no.
Tshawb xyuas thiab tshawb xyuas ib qho los ntawm ib daim ntawv pov thawj raws li cov steel zoo daim ntawv pov thawj thiab loj cov lus qhia tshwj xeeb, thiab tshawb xyuas cov khoom zoo saum npoo av, tuab thiab thaj chaw hauv zos ntawm cov hlau. Yuav tsum tsis muaj lamination, slag suav nrog thiab lwm yam tsis xws luag thaum kawg los yog txhuam ntawm cov hlau.
2. Cov khoom siv vuam: cov khoom siv vuam siv xav tau kom phim cov hlau siv hauv qhov phiaj xwm. Vim tias qhov zoo sib txawv ntawm cov khoom sib txawv ntau lawm, kev xyuas chaw yuav tsum tau nqa tawm hauv cov khoom ntau ntau raws li cov neeg xav tau.
Cov khoom siv hluav taws xob thiab fluxes yuav tsum tau khaws cia kom zoo thiab yuav tsum tsis txhob thawm, txwv tsis pub cov txheej txheem kev ua haujlwm ntawm kev ua haujlwm yuav raug cuam tshuam, tab sis kuj cuam tshuam lub cev thiab tshuaj ntawm cov pob qij txha yuav raug cuam tshuam tsis zoo. Qhov kev xeem vuam yuav tsum tau ua dua tom qab xa cov khoom siv vuam tso rau ntev dhau los yog damped.
III. Blanking thiab lub qhov ua kom tswj tau
1. Ua ntej txiav, qhov huv, flatness, txiav qhov loj me, ntu roughness, kev txiav txim siab, tsis tshua muaj qhov tob thiab zawj kaum ntawm cov qauv steel saum npoo yuav tsum ua tau raws li qhov yuav tsum tau ua; nplaim ntawm kev sib dhos thiab chaw txuas hlau yuav tsum tau kho.
2. Kev npaj tawm: rau kev sib dhos ntawm txhua yam thiab qhov chaw, thiab kev sib dhos ntawm cov khoom sib dhos ua ntej cov chaw, kev teeb tsa cov neeg ua haujlwm yuav tsum ua tiav qhov chaw teeb tsa ntawm cov txheej txheem ua tiav thiab lub rooj sib txoos loj loj. Tom qab teeb tsa, nws yuav tsum raug kuaj xyuas los ntawm tus neeg tshuaj xyuas kom paub tseeb tias qhov ntsuas ntawm lub ntsuas qhov loj thiab lub kaum sab xis ntawm cov khoom sib dhos.
Tus qauv drilling, txuas cov phaj thiab phaj sib koom ua ke tom qab kev sib nug xov sau rau datum kab ntawm lub cev; lub qhov eccentricity, lub qhov deb offset, lub qhov nyob deb li cas, roundness thiab verticality, lub qhov phab ntsa thiab lub qhov taub ntug qhov chaw zoo yuav tsum nruj me ntsis. Txhawm rau kom ntseeg tau qhov tseeb thiab qhov zoo ntawm qhov drilling, qhov teeb tsa cov neeg ua haujlwm yuav tsum tau teeb tsa thiab kos tawm lub datum axis thiab nruab nrab ntawm lub qhov thaum siv cov tuag drilling.
IV. Los ua ke tswj hwm
1. Lub zog, kev nruj, qib thiab cov cuab yeej cuam tshuam thiab cov khoom siv sib dhos ntawm lub rooj sib txoos ua ke thiab molding txaj; qhov loj me ntawm kev nthuav dav thiab tshwj xeeb pwm; cov khoom siv, naj npawb, qhov loj me, kev ua kom raug, qhov ntau, txuas thiab kho qhov chaw ntawm vuam qhov chaw ntawm seem; lub dav hlau datum, kab datum, hla txoj kab nruab nrab, sib dhos ua ke kab ntawm qhov seem; lub rooj sib dhos txoj haujlwm, kev taw qhia, lub kaum ntse ntse thiab lub siab ntawm qhov sib txawv, txiav txim siab, lub camber, lub kaum sab xis ntawm qhov zawj, blunt ntug, kev tshem tawm, kev sib khi ntawm rov qab phaj thiab cais ntawm kev sib koom tes; sib dhos ua ntu zus thiab txoj kev, ntxiv vuam shrinkage thiab machining pub; qhov loj me, ntev, qhov txawv, txoj hauj lwm thiab saum npoo zoo ntawm muab tso rau kev vuam.
2. Lub rooj sib xyaw ua ke: cov khoom sib koom ua ke yog hais txog qhov chaw vuam thiab muab tso rau kev txhim kho ua ntej ua ntej sub hlau sib tsoo. Ua ntej sib dhos, cov khoom me me yuav tsum raug kho. Kev teeb tsa tus neeg ua haujlwm yuav kos tawm txoj kab nruab nrab thiab kab hauv kev ua haujlwm. Qhov nqaij ntawd qhov chaw kho yuav tsum tau ua tom qab kev tshuaj xyuas tau tsim nyog, thiab kev vuam raug cai yuav tsum xa tom qab tshuaj xyuas.
V. Kev kho kom zoo
1. Kev txhim kho: kev ua haujlwm kho ua haujlwm dhau los ntawm tag nrho cov txheej txheem ntawm cov qauv siv hlau ua, los ntawm blanking mus rau seem, submerged arc vuam, sib dhos phau ntawv vuam thiab lwm yam, yuav tsum tau kho kom ntseeg tau tias qhov loj, zoo thiab cov duab ntawm cov khoom ua tau raws li cov kev xav tau ntawm cov lus qhia tshwj xeeb, thiab nruj tswj hwm khoov thiab sib txuam.
2. Kev sib txhuam saum npoo kev kho: qhov kawg ntawm kev sib txhuam ntawm qhov sib txuas ntawm sab tivthaiv yuav tsum tau milled los ntawm lub tshuab milling, thiab txhuam qhov sib txhuam yuav tsum tau kho los ntawm kev tua cov tshuab tua kab los tsim cov xeb hauv qab ntuj. Nyob rau tib lub sijhawm, tib cov ntaub ntawv thiab cov txheej txheem kev siv yuav tsum siv los ua cov ntawv sib tw rau kev txhuam cov txhuam kev sib txhuam, thiab kev sib txhuam coefficient kuaj yuav tsum tau ua kom ntseeg tau tias kev sib txhuam coefficient ua tau raws li cov cai.
3. Lub ntsej muag kho cov khoom siv: cov txheej txheem ua tiav, cov khoom siv thiab cov khoom siv yuav tsum tau ua tiav raws li cov kev cai, burr, vuam slag, vuam vias, av, thiab lwm yam yuav tsum tau muab tshem tawm, thiab soj ntsuam saum npoo yuav tsum tau ua. Tom qab cov Cheebtsam tiav lawm thiab saum npoo huv huv, qhov saum npoo yuav tsum tau muab faus nrog lub koob tshuaj tiv thaiv blasting tshuab.
VI. cov khoom tiav tiav tshuaj xyuas
Cov kab cim steel muaj xws li kos duab Zauv, feem Kab No., kab axis, xoom kab, 1m kab nce siab thiab lawv cov kev taw qhia thiab chaw. Seb tag nrho ntev, ntu loj, curvature, ntswj, camber, inclination ntawm ob xaus, kab pheeb ces kaum ntawm dav hlau, zawj welded rau ntawm qhov chaw, qhov nrug thiab txoj hauj lwm loj ntawm installation qhov yog tsim nyog, zoo li zoo ntawm feem thiab chamfer ntawm txiav dawb ntug, lwm yam.
Nrog rau kev txhim kho txuas ntxiv ntawm lub neej, steel qauv tau maj mam siv rau peb niaj hnub, yog li thaum ua cov khoom lag luam, peb yuav tsum thov peb cov neeg ua haujlwm tsim kho thiab cov neeg ua haujlwm tsim kho kom ua raws li cov txheej txheem ua tau zoo saum toj no, kom ntseeg tau tias cov kev ua tau zoo. Cov. Thaum lub sijhawm tsim kho, peb yuav tsum ua raws li cov theem qhia kev ua haujlwm, thiab tom qab ntawd xyuas kom qhov kev tsim kho. Cov txheej txheem zoo ntawm cov txheej txheem, thiab tom qab ntawd ua rau cov khoom lag luam muaj ob zaug lav.
