Nyob rau hauv high-kawg tsim teb xws li lub zog nuclear, kev lag luam tshuaj, thiab marine engineering tau dhau los ua cov khoom tseem ceeb thiab corrosion tsis kam. Raws li nws cov ntaub hlau vuam, 2209 Vuam hlau tau maj mam hloov qhov teeb meem ntawm kev tshawb fawb los ntawm kev tshawb fawb hauv tsev tsis ntev los no, thiab tau dhau los ua qhov tsom kwm ntawm kev lag luam kev lag luam.
Cov yam ntxwv tseem ceeb thiab Qhov Zoo ntawm 2209 Vuam Hlau
22 {{0 9 vuam hlau belongs rau Duplex Steel Stainless Hlau Vuam Cov Khoom Siv. Nws cov hlau tso tawm yog tsim ntawm Austenite thiab ferrite (feem ntau yog nyob rau hauv ib tug piv ntawm 30% {%), thiab tsis kam, thiab kev ntxhov siab corrosion. Piv txwv li, cov tso tawm hlau tensile zog ntawm qib nuclear nyob rau ntawm 75%}} fn, uas tau ua tiav cov qauv hluav taws xob asme nuclear. Tsis tas li ntawd, nws cov impurity cov ntsiab lus (xws li s, p) muaj tsawg heev (0.004% {12}}. 007%), uas txo qis kev pheej hmoo ntawm kev cuam tshuam ntawm corrosion intergranular.
Kev R & D thiab thev naus laus zis
Rau ib lub sijhawm ntev, domestic rhawv hlau stainless hlau vuam cov ntaub ntawv tau cia siab rau cov txiaj ntsig tsis ntev los no hloov chaw hauv tsev:
Submerged Arc Vuam cov khoom siv: tus ywj pheej tsim Saw2209 Vuam Hlau Thiab SJ676 Alkaline Flux tau daws cov teeb meem tsis zoo slag tshem tawm thiab swb rau kev sib cais. Cov kev ua tau zoo ntawm cov ntawv tso nyiaj tso tawm piv rau cov khoom lag luam txawv teb chaws thiab tau ua tiav zoo rau cov khoom sib tw loj.
Flux-cored vuam hlau: Qhov kev cuam tshuam lub zog ntawm kev ua haujlwm hauv tsev 220 9}} qib yog 33% siab dua ntawm cov khoom lag luam txawv teb chaws, thiab cov pitting corrosion yog qhov zoo dua. Nws tau siv rau vuam ntawm cov dej hiav txwv xav tau khoom siv dej hiav txwv.
Nuclear zog qib vuam hlau: kev ua tau zoo ntawm cov qhab nia hauv tsev yog qhov zoo dua, thiab cov khoom siv ferrite yog qhov zoo dua, uas pab tau lub zog ap1000 ua haujlwm.
Txheej txheem ua kom zoo thiab siv cov xwm txheej
Kev ua haujlwm vuam ua haujlwm ntawm 2209 Vuam hlau yog muaj nyob ntawm cov txheej txheem tsis muaj:
Cov tswv yim kub tswj hwm: kev tshawb fawb tau pom tias thaum cov lus qhia tshav kub yog 1.15KJ / MON, ob-theem sib piv ntawm Weld yog qhov zoo tshaj plaws.
Welding method adaptation: Suitable for GMAW-P (pulsed gas shielded welding), SAW (submerged arc welding), TIG (tungsten inert gas arc welding) and other processes, especially in the welding of UNS S32101 and 2205 dual-phase steel.
Overlay Field TIG los yog electroslag overlay (ESSC
Cov kev sib tw thiab yav tom ntej prospections
Txawm hais tias 2209 vuam hlau muaj kev ua tau zoo heev, nws tseem tsim nyog kom them sai sai rau σ nplooj siab nag lossis nag lossis kub. Cov kev tshawb fawb tau pom tias kev kawm ntev ntawm 690 degree yuav txo qis kev cuam tshuam nyuaj, uas yuav tsum tau zam dhau kev ua haujlwm tom qab weld lossis kev kho cua sov. Nyob rau yav tom ntej, nrog rau daim ntawv thov ntawm tshiab thev naus laus zis xws li WAAMCOLEATING), lub peev xwm vuam hlau hauv 3D luam tawm ntawm cov khoom siv ua 3D yuav raug tso tawm ntxiv.

Kev tawg hauv lub zos ntawm 2209 Vuam hlau tsis tsuas yog txhim kho cov cuab yeej ywj pheej, tab sis kuj tseem nyob hauv qhov chaw nyob hauv lub ntiaj teb chav ua lag luam. Nrog cov txheej txheem ua kom zoo thiab thev naus laus zis yuav nthuav tawm ntawm cov chaw lag luam ib txwm muaj xws li lub zog tshiab thiab kev sib sib zog nqus dej ua ke rau hauv Tuam Tshoj cov khoom lag luam.
