1. Txiav daim ntawv teev npe
Cov txheej txheem no suav nrog kev tshuaj xyuas cov ntaub ntawv, suav nrog kev lees paub ntawm tus qauv thiab cov lus qhia tshwj xeeb uas tau xaiv rau qhov project, nrog rau kev kuaj xyuas cov ntaub ntawv zoo.
2. Layout thiab Marking
① Thaum lub sij hawm layout marking, qhia meej meej cov cim los ua ke, bolt qhov markings, txoj hauj lwm thiab kev taw qhia ntawm stiffening daim hlau, tilt marks, centerlines, siv kab, thiab tshuaj xyuas kab. Tsim cov qauv yog tsim nyog.
② Xav txog kev them nyiaj rau vuam shrinkage thaum lub sij hawm fabrication thiab installation; txiav, ntug npaj, thiab milling ua nyiaj pub dawb; thiab installation qhov yuav tsum tau.
③ Ua ntej kos npe, kho qhov khoov lossis deformation ntawm cov khoom.
3. Txiav
Cov hlau phaj yog txiav siv CNC multi- taub hau txiav tshuab. Ua ntej txiav, tshem tawm cov xeb thiab cov kab mob ntawm qhov chaw txiav kom huv si thiab du. Tom qab txiav, tshem tawm slag thiab splatter. Cov neeg ua haujlwm yuav tsum paub siv cov cuab yeej siv tshuab thiab kho cov cuab yeej tsis ua haujlwm kom muaj txiaj ntsig zoo.
4.Assembly thiab tsim
Ua ntej sib dhos, kho txhua qhov deformation ntawm cov hlau kom ntseeg tau tias nws ntog hauv qhov sib txawv ntawm kev tswj hwm. Cov chaw tiv tauj yuav tsum tsis pub muaj burrs, cov kab mob, thiab cov khib nyiab kom lav qhov sib dhos nruj ntawm cov khoom thiab ua raws li cov qauv zoo. Siv cov cuab yeej thiab cov cuab yeej tsim nyog, xws li txoj cai - lub kaum sab xis steel kav, kom paub meej txaus tom qab sib dhos. Cov khoom siv yog Z12 seem steel sib dhos tshuab.
5. vuam
① Cov cuab yeej siv: Gantry - hom tsis siv neeg submerged arc vuam tshuab.
② Vuam txheej txheem:
Gantry tsis siv neeg submerged arc vuam yog siv rau vuam steel kab thiab kab; phau ntawv welding yog siv los txuas cov phaj thiab stiffeners ntawm txhua kab thiab kab.
Yuav tsum tau rau gantry tsis siv neeg vuam:
(1) Tshem tawm xeb, burrs, thiab cov kab mob tsis pub dhau 30-50 hli ntawm qhov vuam ntug kom txo tau cov khoom uas tuaj yeem ua rau vuam tsis xws li porosity.
(2) Cov phaj txhuas yuav tsum yog cov khoom siv tib yam li cov hlau hauv paus, nrog rau tib daim ntawv vuam zawj, thiab nws qhov ntev yuav tsum ua raws li cov qauv kev qhia tshwj xeeb.
Cov kev xav tau rau kev tuav arc vuam: Siv lub vuam zoo nrog kev ua haujlwm tag nrho, thiab ziab cov electrodes uas tau xaiv hauv qhov cub kom qhuav.
6.Qhov Ua
7.Section Steel Straightening
① Khoom siv: Flange straightening tshuab.
② Cov txheej txheem yuav tsum tau ua: Cov neeg ua haujlwm yuav tsum paub txog cov txheej txheem cov ntsiab lus thiab paub cov txheej txheem ua haujlwm ntawm cov khoom siv. Tom qab ua kom ncaj, yuav tsum tau soj ntsuam tus kheej ntawm tus kheej, thiab qhov sib txawv uas tso cai yuav tsum ua raws li cov kev cai ntawm "Steel Structure Construction and Acceptance Code."
8.Txoj kev txiav
Tom qab welded seem steel kab thiab kab teeb yog ncaj, lawv qhov kawg yuav tsum tau txiav tiaj tus siv lub tshuab kawg milling.
9. Kev tshem tawm xeb
Kev tshem tawm xeb yog ua los ntawm cov khoom siv tshwj xeeb. Kev txhaj tshuaj blasting tuaj yeem txhim kho lub zog qaug zog thiab corrosion tsis kam ntawm cov hlau. Nws kuj tseem txhim kho qhov tawv tawv ntawm cov hlau mus rau qhov sib txawv, uas muaj txiaj ntsig zoo rau xim adhesion yam tsis tas yuav tsum tau txheej txheej ntxiv. Cov abrasives siv rau kev tshem tawm xeb yuav tsum ua tau raws li cov qauv zoo thiab cov txheej txheem yuav tsum tau ua. Cov av noo ntawm qhov chaw tsim kho yuav tsum tsis pub tshaj 85%. Tom qab tshem tawm xeb, ntxuav cov hlau nto nrog cov cuab yeej xws li txhuam hniav ua ntej mus rau kauj ruam tom ntej. Yog hais tias cov hlau nto rusts dua ua ntej priming, nws yuav tsum raug tshem tawm xeb dua.
10. Painting
Tom qab kev tshem tawm xeb raug tshuaj xyuas thiab pom zoo, siv thawj lub tsho tiv no ntawm primer. Feem ntau, yog tias cov hlau khaws cia hauv tsev tom qab tshem tawm xeb, cov primer yuav tsum tau siv rau hauv 24 teev. Yog tias khaws cia sab nraum zoov, cov primer yuav tsum tau siv rau tib lub sijhawm ua haujlwm. Cov xim yuav tsum tau siv ua ke ua ke raws li qhov xav tau los ntawm kev tsim qauv. Tom qab thawj lub tsho tiv no ntawm primer tau qhuav, siv cov tsho loj nruab nrab thiab sab saum toj kom ntseeg tau tias cov txheej tuab raws li cov qauv tsim. Cov xim yuav tsum tau thov tusyees tsis sagging.
11. Ntim thiab thauj
① Ua ntej ntim, hloov ntau yam cim rau hauv cov khoom siv tus lej uas tau teev tseg hauv cov duab kos duab, thiab kos lawv nrog tus cwj mem (xim) lossis cov ntawv nplaum rau ntawm qhov chaw ntawm cov khoom siv rau kev txheeb xyuas thaum ntim.
② Thaum tuav, tiv thaiv cov khoom thiab cov txheej txheem, thiab muab kev tiv thaiv tsim nyog rau cov chaw tsis muaj zog.
③ Yog hais tias cov khoom yog deformed los yog puas thaum tuav, kho tam sim ntawd kom paub tseeb tias lawv nyob rau hauv zoo meej ua ntej xa zaub mov.
12. Txais
Ua ntej steel Cheebtsam tawm ntawm lub Hoobkas, cov ntaub ntawv hauv qab no yuav tsum tau xa:
(1) Daim ntawv pov thawj khoom
(2) Cov duab kos thiab tsim cov ntaub ntawv
(3) Daim ntawv cog lus hais txog cov teeb meem kev lag luam thaum tsim khoom
(4) Cov ntawv pov thawj zoo lossis cov ntawv xeem rau cov hlau, cov khoom sib txuas, thiab cov txheej txheem
(5) Weld soj ntsuam cov ntaub ntawv
(6) Txheej tshuaj xyuas cov ntaub ntawv
(7) Cov ntaub ntawv lees paub tseem ceeb
