1. Dab tsi yog cov ntsiab lus tseem ceeb hauv UNSOY N06200 Nickel Alloy (Hastelloy C2000) thiab lawv cov haujlwm hauv cov ntaub ntawv lag luam hauv chaw lag luam?
UN tsis yog N06200, lossis Hastelloy C2000, muaj ob peb qhov tseem ceeb heev alloying ntsiab. Nickel (NI) cov qauv ntawm lub hauv paus ntawm cov alloy, muab ib qho ruaj khov me me thiab zoo tshaj tag nrho cov corrosion. Hauv cov tshuaj reaptical tshuaj, qhov kev ruaj khov yog qhov tseem ceeb heev li nws tuaj yeem tiv taus cov tshuaj uas nyuaj thiab cov tshuaj uas muaj kev sib raug zoo.
Chromium (CR), tam sim no nyob rau hauv cov kab ntau ntawm 22 - 24%, plays lub luag haujlwm tseem ceeb hauv kev txhim kho cov alloy qhov tsis kam mus rau oxidizing ib puag ncig. Hauv cov ntawv thov tshuaj, ntau yam kev tawm tsam nrog oxidizing cov neeg sawv cev, thiab cov ntaub ntawv chromium ib qho tuab, adherent chromium- olide passive zaj duab xis ntawm alloy nto. Zaj yeeb yaj kiab no ua qhov thaiv kev, tiv thaiv kev ua kom loj dua thiab xeb ntawm cov hlau hauv qab, yog li ua kom muaj kev ncaj ncees ntawm cov tshuaj reactor.
Molybdenum (mo), nrog cov ntsiab lus ntawm 15 - 17%, yog qhov tseem ceeb rau kev txhim kho cov alloy qhov kev tiv thaiv kom txo cov kua qaub. Cov txheej txheem saib xyuas cov tshuaj yuav siv lossis tsim cov kua qaub txo xws li hydrochloric acid. Molybdenum txhim kho lub peev xwm los tawm tsam pitting thiab crevice corrosion nyob rau hauv xws li ib puag ncig, uas yog qhov tseem ceeb rau lub ntev areoor.
Tooj liab (CU), nyob ib ncig ntawm 1 - 2%, ntxiv txhim kho cov alloy cov sulphuric acid thiab hydrofluoric acid. Hauv kev lag luam kev lag luam tshuaj reactors, cov kua qaub no yuav siv rau qee yam kev tawm tsam lossis cov khoom siv ntxuav, muaj cov tshuaj tiv thaiv corrosion thiab tswj hwm tus reactor txoj haujlwm.
2. Yuav ua li cas corrosion resistance ntawm hastelloy c2000 coil pab tau cov tshuaj cas ntawm cov tshuaj ntsuam tshuaj?
Lub corrosion resistance ntawm hastelloy c2000 chev yog qhov tseem ceeb rau cov tshuaj reactors. Firstly, tshuaj lag luam feem ntau muaj feem ntau ntawm cov tshuaj, qee qhov uas muaj kev xeb ntau. Hastelloy C2000 lub peev xwm los tiv thaiv ob qho tib si oxidizing thiab txo cov chaw ib puag ncig ua rau kev siv cov tshuaj uas txawv ntawm cov tshuaj tiv thaiv. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm tej yam tshuaj, cov tshuaj tiv thaiv nruab nrab yuav hloov pauv ntawm oxidizing mus rau ib puag ncig txo thaum sib txawv ntawm cov txheej txheem. Lub Alloy qhov tsis kam rau ob hom ib puag ncig kom ntseeg tau tias cov tshuaj reactor ua los ntawm hastelloy c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 coil c2000 chev tuaj yeem ua kom cov kev hloov pauv no yam tsis muaj kev txhim kho corrosion.
Qhov thib ob, cov txheej txheej coil ntawm haastelloy C2000 tuaj yeem yooj yim ua rau cov tshuab ua kom sov sov hauv cov reactor. Hauv cov txheej txheem tshuaj, kev hloov pauv kub feem ntau yuav tsum tau siv los hloov cov txheej txheem cua sib txawv ntawm cov txheej txheem sib txawv. Cov corrosion tsis kam ntawm alloy kom cov cua sov ua kom sib xyaw ua ke thaum lub sijhawm cua sov {} hloov cov txheej txheem thiab paug cov khoom lag luam. Kev tsis huv hauv kev tsim khoom lag luam yog qhov hnyav heev li nws tuaj yeem cuam tshuam cov tshuaj zoo thiab kev nyab xeeb.
Ntxiv mus, qhov siab corrosion tsis kam ntawm hastelloy c2000 coil txuas cov kev pabcuam lub neej ntawm cov reactor. Qhov no txo cov zaus ntawm reactor hloov lossis kev saib xyuas vim yog corrosion-} cov teeb meem ntsig txog. Hauv kev lag luam kws tshuaj, qhov twg ntau lawm txuas ntxiv, txo qis downtime rau kev saib xyuas yog qhov xav tau. Ib qho ntev dua -} Lasting reactor ua los ntawm hastelloy c2000 coil pab kom ntseeg tau cov nqi sib txuam nrog cov khoom siv sib txuas thiab kev txij nkawm.
3. Dab tsi yog cov txheej txheem raug thiab tsim cov txheej txheem rau hastelloy c2000 chev siv hauv kev lag luam kev lag luam, thiab kev ceev faj dab tsi?
Kev tsim khoom ntawm hastelloy c2000 chev pib nrog melting thiab casting ntawm alloy. High - Cov ntaub ntawv muaj kev npau suav yog siv los ua kom cov tshuaj muaj txiaj ntsig zoo thiab cov khoom ntawm cov alloy. Thaum lub sij hawm melting, nruj kev tswj hwm kub thiab huab cua yog qhov tsim nyog los tiv thaiv kev sib kis. Ib zaug nrum rau hauv cov pob zeb lossis cov nqi ua haujlwm, cov no yog qhov kub kub - rolled kom txo cov thickness thiab txhim kho microstructure.
Txog kev sib sau lub coil, txias - rolling yog ib qho txheej txheem. Txias - rolling pab kom ua tiav qhov kev xav tau qhov tseeb thiab qhov tseeb ua tiav rau lub kauj. Txawm li cas los xij, thaum txias - rolling, ua haujlwm hnyav tuaj yeem tshwm sim. Txhawm rau tawm tsam qhov no, analmediate anealing yuav tsim nyog. Annealing yog nqa tawm ntawm cov kub tshwj xeeb (feem ntau nyob ib ncig ntawm1100 - 1150℃rau hastelloy c2000) kom daws tau qhov txias rau hastelloy, ua kom yooj yim dua li txias- rolling cov txheej txheem.
Thaum tuav Hastelloy C2000 Chev thaum tsim thiab sib sau, ceev faj yuav tsum tau coj mus rau kev paug.
