Kev npaj khoom siv

Kev npaj cov khoom yog qhov pib ntawm steel qauv fabrication, thiab nws qhov zoo ncaj qha cuam tshuam rau tag nrho cov txheej txheem ua haujlwm tom ntej. Lub luag haujlwm tseem ceeb ntawm theem no suav nrog kev lees txais cov khoom siv, straightening thiab deg tu. Tom qab cov ntaub ntawv steel tuaj txog ntawm lub hoobkas, lawv cov ntaub ntawv pov thawj yuav tsum tau kuaj xyuas cov khoom tiag. Kev tshuaj xyuas cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab yuav tsum tau ua rau cov hlau siv hauv cov khoom siv loj. Deformed steels tshwm sim thaum lub sij hawm thauj mus los yuav tsum ncaj nraim siv cov menyuam straighteners los yog hydraulic jacking tshuab. Kev paub qhia tau hais tias kwv yees li 80% ntawm qhov ua yuam kev hauv qhov blanking tshwm sim los ntawm cov ntaub ntawv tsis ncaj ncees.

Lofting

Lofting yog thawj kauj ruam tseem ceeb rau kev tswj xyuas qhov tseeb hauv steel qauv tsim. Ntawm cov platforms tshwj xeeb lossis cov rooj teeb tsa, cov kws tshaj lij kos cov khoom sib txuas ua ke thiab cov txheej txheem ntawm qhov sib piv ntawm 1: 1 raws li kev tsim cov duab kos los txheeb xyuas cov duab ntawm qhov chaw. Ntxiv nrog rau kev txheeb xyuas qhov ntev ntawm qhov kos duab, qhov nyiaj welding shrinkage yuav tsum tau tshwj tseg raws li cov txheej txheem cuam tshuam. Feem ntau, qhov nyiaj pub dawb ntawm 1 txog 1.5 millimeters yuav tsum tau muab tso tseg rau txhua lub pob tw.

Kos npe

Kuj tseem hu ua scribing, kos npe yog hais txog cov txheej txheem ntawm kev siv cov qauv los kos cov haujlwm ntawm lub qhov thiab cov kab machining rau cov txheej txheem ntawm cov hlau phaj thiab cov seem. Lub hauv paus ntsiab lus ntawm "qhov loj ua ntej, qhov me me tom qab" yog ua raws li kev siv cov khoom siv ntau tshaj plaws. Los ntawm optimized layout, tag nrho cov khoom siv tus nqi tuaj yeem ncav cuag ntau dua 85%, thiab nws tuaj yeem tshaj 92% tom qab ua kom zoo dua zes.

Txiav

Txiav yog cov txheej txheem ntawm kev sib cais cov ntaub ntawv raw rau hauv ib tus neeg qhov chaw raws kab cim. Cov txheej txheem tseem ceeb yog txiav cov roj, txiav cov ntshav thiab laser txiav. Daim ntawv thov dav ntawm cov lej tswj kev siv tshuab tau txhim kho qhov tseeb thiab kev ua haujlwm ntawm steel qauv fabrication. Qee qhov chaw txiav tau tsim nyog rau kev sib txuas ncaj qha yam tsis muaj kev ua haujlwm thib ob.

Kev tsim

Cov khoom uas tsis yog-linear xws li cov kab nkhaus thiab cov kav dej khoov yuav tsum tau zoo li ntawm kev khoov txias lossis kub dabtsi yog khoov. Txias dabtsi yog khoov yog ua nyob rau hauv chav tsev kub thiab muaj feem xyuam rau feem ntau nkhaus Cheebtsam. Rau kub dabtsi yog khoov, steels yog rhuab mus rau 900-1100 ° C ua ntej khoov, uas yog saws rau tuab daim hlau los yog cov khoom uas muaj me me dabtsi yog khoov radii.

Kev sib dhos

Kev sib dhos txhais tau hais tias muab cov khoom ua tiav raws li qhov xav tau los ntawm kev kos duab thiab kho lawv ib ntus los ntawm tack welding. Cov txheej txheem sib dhos txheej txheem yog raws li hauv qab no: Sib tsoo splice seams ntawm flange daim hlau → Tshem tawm burrs ntawm lub vev xaib → Ua tiav qhov tseeb nrog lub tshuab sib dhos → Ua kom tiav ntawm ib sab T-section steel → Tig lub rooj sib dhos thiab ua tiav tag nrho cov txheej txheem.

Vuam

Vuam yog cov txheej txheem tseem ceeb hauv kev tsim steel qauv nrog cov kev cai siab thiab kev tswj xyuas nruj. Cov kev siv vuam siv feem ntau muaj xws li tsis siv neeg submerged arc vuam, CO₂ roj shielded vuam thiab shielded hlau arc vuam.

Ncaj ncaj

Thermal stress generated thaum lub sij hawm vuam yuav ua rau cov khoom deformation, uas yuav tsum tau muab tshem tawm los ntawm straightening kom rov zoo li qub geometric duab. Txoj kev ncaj ncaj muaj xws li cov tshuab ncaj ncaj, nplaim taws ncaj thiab ua ke ncaj ncaj. Cua sov ntawm tib txoj hauj lwm yuav tsum tsis txhob ua ntau tshaj peb zaug, thiab overheating yog nruj me ntsis txwv tsis pub.

Kev tshuaj xyuas

Khiav los ntawm tag nrho cov txheej txheem tsim khoom, kev tshuaj xyuas ua haujlwm yog qhov tseem ceeb lav rau cov khoom zoo. Phased kev soj ntsuam feem ntau suav nrog kev tshuaj xyuas cov khoom siv raw, kev tshuaj xyuas hauv txheej txheem thiab kev tshuaj xyuas tom qab vuam. Kev tuag tsis zoo xws li cov kab nrib pleb thiab tsis tiav fusion tsis raug tso cai hauv cov welds.

Txheej

Txheej muab kev tiv thaiv corrosion thiab tiv thaiv hluav taws rau cov qauv hlau. Cov txheej txheem txheej txheem muaj peb txheej: zinc-nplua nuj epoxy primer, epoxy micaceous hlau nruab nrab lub tsho, thiab polyurethane lossis fluorocarbon topcoat. Hluav taws-resistant txheej yuav tsum tau siv rau hauv ntau lub tsho nyias nyias. Lub ambient kub rau txheej txheej yuav tsum tsis txhob qis dua 5 ° C, cov av noo ntawm cov txheeb ze yuav tsum tsis txhob ntau tshaj 85%, thiab qhov kub ntawm cov hlau yuav tsum yog tsawg kawg yog 3 ° C siab tshaj qhov dew point.

Kev xa khoom los ntawm Hoobkas

Kev xa khoom yog cov kauj ruam kawg ntawm kev tsim steel qauv. Cheebtsam uas dhau qhov kev tshuaj ntsuam zaum kawg yuav raug muab cov lej cim thiab cov cim. Cheebtsam yuav tsum tau bundled nyob rau hauv pab pawg raws li lub installation ib theem zuj zus. Ntoo blocks los yog roj hmab gaskets yuav tsum tau muab tso rau hauv nruab nrab ntawm lub Cheebtsam los tiv thaiv txheej khawb.
