Thaum sivA516 GR70Rau boiler manufacturing, tus tswj yuav tsum nruj me ntsis rau nws cov qauv. Cov neeg ua haujlwm cuam tshuam yuav tsum tswj cov ntaub ntawv kev lees paub, vuam zoo, kev kho cua sov, thiab kev kuaj cua sov}} qhov siab} Kev ua haujlwm siab ntawm boilers.
Ua ntej tsim khoom, cov neeg ua haujlwm tswj xyuas yuav tsum tshuaj xyuas cov ntaub ntawv cov khoom lag luam cov khoom lag luam, kom paub meej tias kev ua tiav rau cov qauv A516 / A516M cov qauv rau Gr70. Cov cim tseem ceeb nrog rau cov tshuaj muaj pes tsawg leeg thiab cov neeg kho tshuab yuav tsum tau lees paub. Tom qab, cov ntaub ntawv kev ua tau zoo yuav tsum raug kuaj los ntawm kev tsom xam tshuaj chem, Tensile kuaj, thiab cuam tshuam kev cuam tshuam. Tsis - Cov ntaub ntawv ua tiav tsis tiav. Ib qho ntxiv, tshawb xyuas qhov zoo ntawm cov phiaj hlau. Tsis xws luag xws li tawg, Lamination, lossis ntsuas tsis raug cai. Thickness sib txawv yuav tsum nrog cov qauv kev qhia kom tsis txhob muaj kev cuam tshuam nrog cov txheej txheem muaj zog.
Cov neeg ua haujlwm ntau lawm yuav tsum ua ntej -}}}}}}}}}}} wel wel,, voltage, ntsuas kub ua ntej kom tiav. Welders yuav tsum tuav daim ntawv pov thawj siv tau rau qhov project tshwj xeeb thiab nruj me ntsis rau kev pom zoo cov txheej txheem thaum lub sij hawm vuam.
Ua ntej vuam muag, cov khoom tsis huv xws li roj thiab xeb los ntawm cov zawj thiab cov chaw nyob ib puag ncig. Ua preheating raws li phaj tuab thiab ambient kub kom tiv thaiv vuam sib tsoo.
Conduct hydrogen removal promptly after welding, especially for thick plates or low-temperature environments, to avoid hydrogen-induced cracking. Lub hydrogen tshem tawm kub yog feem ntau 250-350 degree, nrog tuav lub sijhawm txiav txim los ntawm phaj tuab.
Rau cov phiaj hlau tshaj 40mm nyob rau hauv tuab, kev kho kom zoo li qub, thiab paub meej lub zog {}- kev sib piv.
Welded pob qij txha yuav tsum tau tshaj tawm {{}} Weld Kev Kho Mob Kub (PWHT)
Thaum kev kho cua sov, cua sov, tog cua sov, thiab txias lub sijhawm yuav tsum tau nruj me ntsis los tiv thaiv kev ua phem lossis deformation tshwm sim los ntawm kev kub ntxhov.
Tsis - Kev sim ua txhaum: Welded sib koom tes yuav tsum tau kuaj cov kab nrib pleb, tsis muaj kev sib tw, tsis muaj lwm yam tsis xws luag. Cov qauv kev sim yuav tsum ua raws li kev tsim cov lis dej num uas cuam tshuam rau cov neeg ua haujlwm.
Kev Ntsuam Xyuas Pom: Tom qab ua tiav tiav, tshuaj xyuas lub ntsej muag zoo nkauj kom ntseeg tau tias kom zoo ib yam tsis muaj kev tsis txaus siab uas tsis muaj qhov tsis zoo saum npoo av, lossis tsis sib thooj. Weld qhov ntev yuav tsum ua kom tau raws cov qauv tsim qauv.
Hydrostatic Kev Kuaj: Thaum Boiler Fabrication kev ua tiav, ua hydostatic kuaj ntawm kev tsim qauv tau teev tseg. Qhov tseeb ntawm cov lus qhia tag nrho kev ntseeg siab thiab muaj zog. Thaum kuaj, siab yuav tsum tau nce maj thaum maj mam thaum saib rau txi lossis txheej txheem deformation.
Txiav txim siab cov boiler thaum ua haujlwm kub thiab siab. A516 Gr70 yog tsim nyog rau nruab nrab--} Qhov ntsuas kub tsis pub dhau 450 degree. Yog tias lub boiler ua tsis tu ncua ntawm qhov kub siab dua, ntsuas cov khoom siv lub siab {}} lub zog thiab cov creep cov khoom. Hloov nrog cov cua sov ntau dua -} tiv taus hlau yog tias tsim nyog.
Yog hais tias lub boiler nruab nrab yog corrosive yog corrosive yog corrosive yog corrosive, ntxiv anti - Cov tshuaj tiv thaiv corrosion tau ua los tiv thaiv cov khoom siv xeb tsis ua haujlwm.
