S355JR+410 Clad steel phaj Daim ntawv thov
Daim ntawv thov scenarios ntawm S355JR+410 clad steel daim hlau npog ntau hom kev lag luam, thiab lawv tshwj xeeb tshaj yog haum rau kev ua haujlwm uas yuav tsum tau muaj zog ntawm cov qauv thiab nruab nrab tiv thaiv corrosion. Hauv kev ua haujlwm ntawm marine engineering, lub phaj steel clad no yog siv rau hauv cov khoom xws li cov qauv kev txhawb nqa ntawm offshore platforms, seawater pipelines, thiab cia tso tsheb hlau luam. Ua tsaug rau lub zog siab ntawm S355JR thiab seawater corrosion kuj ntawm 410 stainless hlau, nws muaj peev xwm ua tiav lub neej kev pab cuam ntawm ntau tshaj 15 xyoo nyob rau hauv ib qho chaw ntsev tsuag. Piv nrog cov txheej txheem kev tiv thaiv ib txwm, nws tshem tawm cov nqi ntawm kev saib xyuas tsis tu ncua thiab muaj kev lag luam zoo dua thoob plaws lub neej tag nrho.
Cov khoom siv tshuaj lom neeg thiab kev tiv thaiv ib puag ncig yog lwm daim ntawv thov tseem ceeb. Hauv kev lag luam xws li kev lag luam thee chemical thiab kev tsim cov chiv, S355JR+410 clad steel daim hlau yog siv los tsim cov khoom siv xws li reactor shells, nruab nrab conveying pipelines, thiab cov dej khib nyiab. Lawv tuaj yeem tsis tsuas yog tiv taus lub siab sab hauv (nrog rau kev tsim siab txog li 3.5MPa) tab sis kuj tiv thaiv corrosion los ntawm acid thiab alkali media. Tshwj xeeb tshaj yog nyob rau hauv lub scenario ntawm conveying kua uas muaj hais, lub siab hardness yam ntxwv ntawm lub 410 cladding zoo txo erosion thiab hnav, yog li ncua lub sij hawm ntawm cov khoom tu lub voj voog.
Hauv kev ua haujlwm ntawm lub zog thiab hauv nroog engineering, daim ntawv clad steel no yog tsim rau kev txhawb nqa cov qauv ntawm biomass boilers, flue gas pipelines ntawm khib nyiab incineration fais fab kev tsim khoom, thiab siab -siab hnav- resistant pipelines ntawm hydropower chaw nres tsheb, thiab lwm yam. S355JR puag txheej ua tau raws li lub zog yuav tsum tau nyob rau hauv siab {41}, sulfuridetem resisting thiab dej vapor hauv flue roj, qhia kev ua haujlwm ruaj khov hauv kev ua haujlwm ntawm 200-400 degree. Nws tsis kam mus rau microbiological corrosion kuj tau raug txheeb xyuas hauv cov ntawv thov siv rau cov khoom siv kho mob sludge hauv cov dej phwj tuaj hauv nroog.

Cov txheej txheem ntau lawm thiab kev tswj xyuas zoo
Txoj kev Cladding
Explosive Vuam:
Lub hauv paus ntsiab lus: Lub detonation ntawm explosives tsav lub cladding phaj los cuam tshuam lub hauv paus phaj ntawm kev kub ceev, tsim ib tug metallurgical daim ntawv cog lus ntawm lub interface (wavy interface) nrog ib tug sib txuas lub zog ntawm ntau tshaj los yog sib npaug zos rau 300 MPa.
Qhov zoo: Haum rau cov phaj tuab (cladding thickness Ntau dua los yog sib npaug li 3 hli) nrog rau kev sib koom ua ke txog li 100%.
Kev txwv: Yuav tsum tau ua haujlwm hauv thaj chaw, tus nqi siab, thiab kev ua haujlwm tsawg.
Roll Bonding:
Lub hauv paus ntsiab lus: Lub hauv paus phaj thiab cladding phaj yog dov thiab sib koom ua ke ntawm qhov kub thiab txias, thiab daim ntawv cog lus metallurgical yog tsim ntawm qhov sib cuam tshuam los ntawm kev sib kis.
Qhov zoo: Haum rau nyias daim hlau (cladding thickness Ntau dua los yog sib npaug rau 1 hli), tus nqi qis, thiab muaj peev xwm ua haujlwm tas li.
Cov kev txwv: Kev tswj kom nruj ntawm cov cua sov yuav tsum tau (kom tsis txhob oxidation lossis carburization), thiab lub zog sib txuas yog me ntsis qis dua qhov tawg vuam.
Cov Qauv Zoo
Bonding Strength: Shear zog Ntau dua los yog sib npaug rau 200 MPa (EN 10028-7), thiab kev ntsuam xyuas tsis muaj kev puas tsuaj ua raws li GB / T 8165 Qib I tus qauv (tus nqi sib cog lus 100%).
Nto Zoo: Qhov roughness ntawm lub cladding txheej Ra Tsawg dua los yog sib npaug rau 3.2μm, tsis muaj kab nrib pleb, delamination, lossis lwm yam tsis xws luag.
