Cov khoom siv hlau loj, raws li cov tub ntxhais thauj khoom-cov kabmob hauv cov haujlwm loj xws li cov tsev, txuas hniav, lub zog cua, thiab lub zog nuclear, ncaj qha txiav txim siab txog kev nyab xeeb ntawm cov qauv thiab kev pabcuam lub neej ntawm cov qauv engineering los ntawm lawv cov kev tsim khoom thiab vuam zoo. Tsis zoo li cov khoom lag luam, cov khoom siv hlau loj yog cov yam ntxwv ntawm lawv qhov loj me, cov qauv tsim, thiab kev ua haujlwm nruj. Lawv yuav tsum tau ua tib zoo kawg nkaus -rau- xaus kev tswj hwm thiab kev siv vuam tshuab kom ua tiav qhov kev hloov pauv ntawm cov duab kos rau cov khoom tsim nyog, muab kev txhawb nqa tseem ceeb rau ntau yam haujlwm loj.
Qhov tseem ceeb ua ntej rau kev tsim khoom customized yog qhov tseeb nrog cov kev xav tau thiab kev tsim qauv tsim. Thaum lub sijhawm pib ua haujlwm, pab pawg kws tshaj lij yuav tsum koom nrog hauv - kev sib txuas lus tob nrog tus neeg siv khoom, tshuaj xyuas cov ntsiab lus tseem ceeb xws li kev tsim vaj tsev, kev thauj khoom- cov kev xav tau ntawm cov kabmob, thiab kev teeb tsa. Raws li cov qauv kev lag luam cuam tshuam, kev tsim kho kev daws teeb meem raug tsim. Kev tsim qauv tsim tsis yog tsuas yog siv cov qauv qauv thiab kev suav cov tshuab ntawm cov khoom, tab sis kuj yuav tsum tau npaj tshwj xeeb rau cov txheej txheem vuam, qhia meej txog qhov tseem ceeb xws li kev xaiv cov khoom siv vuam, cov txheej txheem vuam, thiab cov txheej txheem vuam. Piv txwv li, rau cov khoom uas raug dynamic loads, xws li cua turbine yees, siab -lub zog qis- alloy vuam hlau yuav tsum tau xaiv, thiab weld bevel daim ntawv optimized los txo cov kev cuam tshuam ntawm vuam kev nyuaj siab ntawm cov khoom siv, kom ntseeg tau tias muaj peev xwm thiab kev nyab xeeb.
Kev tswj cov khoom raw yog ib qho tseem ceeb ntawm kev ua kom cov vuam zoo. Cov khoom siv hlau loj feem ntau siv siab - lub zog steel xws li Q355 thiab Q460. Thaum tuaj txog, cov khoom siv raw tau ua cov txheej txheem tshuaj xyuas nruj, suav nrog kev sim ua tiav ntawm lawv cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov tsos zoo los tiv thaiv cov khoom tsis zoo los ntawm kev siv hauv kev tsim khoom. Nyob rau tib lub sijhawm, cov khoom siv vuam yuav tsum tau ua raws li cov yam ntxwv ntawm cov khoom siv hauv paus thiab muab khaws cia rau hauv qhov chaw qhuav, zoo - qhov cua qhov cua kom tsis txhob ya raws thiab xeb los ntawm kev cuam tshuam cov txiaj ntsig vuam. Tsis tas li ntawd, rau qhov tseem ceeb ntawm cov khoom, pretreatment ntawm cov hlau yog tsim nyog, siv cov txheej txheem xws li txhaj tshuaj blasting los txhim kho deg huv si thiab txhim khu kev sib txuas lub zog ntawm weld pob qij txha.
Vuam yog cov txheej txheem tseem ceeb hauv kev tsim cov hlau loj loj, ncaj qha txiav txim siab lawv cov qauv kev ruaj ntseg thiab thauj khoom -cov kabmob muaj peev xwm. Thaum lub sijhawm tsim khoom, cov txheej txheem vuam tsim nyog yuav tsum raug xaiv raws li cov yam ntxwv ntawm cov qauv thiab vuam nyuaj ntawm cov khoom. Cov txheej txheem muaj xws li submerged arc vuam, gas shielded vuam, thiab hluav taws xob arc vuam. Rau cov nodes nyuaj lossis tuab phaj vuam, ntau- txheej, ntau- txheej txheem vuam yog ua haujlwm, nrog rau kev tswj xyuas nruj xws li vuam tam sim no, qhov hluav taws xob, thiab vuam ceev rau txhua qhov vuam kom tsis txhob vuam tsis xws li kev nkag mus tsis tiav, porosity, thiab tawg. Lub caij no, cov kws tshaj lij vuam cov kws tshaj lij tau raug xaiv los ua cov txheej txheem vuam, thiab cov ntaub ntawv ceev faj tau muab khaws cia thoob plaws kom ntseeg tau tias tus qauv thiab traceability ntawm cov txheej txheem vuam. Txhawm rau hais txog qhov muaj peev xwm rau vuam deformation thaum lub sij hawm vuam ntawm cov khoom loj, kev tiv thaiv kev tiv thaiv xws li kev txhim kho tsis zoo thiab ua ntej - deformation yog siv ua ntej. Tom qab-weld, kev laus kev kho mob yog siv los tso cov kev ntxhov siab welding, kom ntseeg tau qhov tseeb qhov tseeb ntawm cov khoom.
Kev tshuaj xyuas zoo thiab kev lees paub tus me nyuam yog cov kauj ruam kawg tseem ceeb hauv kev tsim khoom. Tom qab vuam, kev tshuaj xyuas zoo yog ua. Kev tshuaj xyuas niaj hnub suav nrog kev tshuaj xyuas qhov muag thiab ntsuas qhov ntsuas qhov ntsuas. Cov cheeb tsam tseem ceeb kuj yuav tsum tsis yog -cov txheej txheem kuaj kev puas tsuaj xws li kuaj ultrasonic thiab kuaj hluav taws xob kom raug txheeb xyuas qhov tsis xws ntawm vuam sab hauv. Cheebtsam uas dhau kev soj ntsuam tau txais kev kho mob tom ntej xws li txheej txheej los txhim kho corrosion thiab xeb tiv thaiv thiab txuas ntxiv kev pab cuam lub neej. Thaum kawg, kev npaj ntim khoom thiab kev thauj mus los tau raug tsim los raws li qhov loj me thiab kev thauj mus los. Cov cuab yeej tshwj xeeb nqa thiab cov cuab yeej ruaj ntseg yog siv los tiv thaiv deformation lossis kev puas tsuaj thaum lub sijhawm thauj mus los, kom ntseeg tau tias muaj kev nyab xeeb thiab raws sij hawm xa khoom ntawm cov khoom tsim nyog rau cov khoom siv steel rau qhov project site.
Kev tsim kho thiab vuam ntawm cov hlau loj loj yog ib txoj haujlwm tsim nyog uas yuav tsum tau ua tib zoo saib xyuas thoob plaws hauv tag nrho cov txheej txheem, los ntawm kev thov kev sib koom tes thiab kev daws teeb meem rau kev tswj cov khoom siv raw, vuam thiab kev tsim khoom, thiab kev tshuaj xyuas zoo. Tsuas yog los ntawm kev ua raws li cov qauv kev tsim khoom tsim nyog thiab tso siab rau pab pawg kws tshaj lij thiab cov cuab yeej tsim khoom siab tshaj tuaj yeem ua tau siab - cov khoom siv hlau zoo uas ua tau raws li cov neeg siv khoom xav tau thiab cov qauv tsim qauv tsim, yog li tso lub hauv paus ruaj ntseg rau kev ua tiav ntawm ntau yam haujlwm loj.
