Dab tsi yog cov txheej txheem tsim khoom ntawm UNS S32950 duplex stainless hlau xaim?

1. Raw khoom xaiv thiab npaj
Ua ntej, cov khoom siv raw yog raug xaiv raws li cov qauv ntawm UNS S32950 duplex stainless hlau hlau. Nws cov khoom tseem ceeb yog ntau yam hlau alloy xws li hlau (Fe), chromium (Cr), npib tsib xee (Ni), molybdenum (Mo), thiab cov ntsiab lus ntawm txhua lub ntsiab lus yuav tsum nruj me ntsis tswj nyob rau hauv qhov kev teev tseg. Kev soj ntsuam nruj nruj yog ua tiav ntawm cov khoom siv raw kom paub meej tias tsis muaj impurities thiab pom tseeb qhov tsis xws luag, muab lub hauv paus zoo rau kev smelting tom ntej.
2. Melting thiab refining
Cov khoom siv raw khoom tau muab tso rau hauv cov cua sov siab tshaj plaws, xws li hluav taws xob arc rauv, thiab cov khoom siv raw yog melted ntawm qhov kub thiab txias los tsim cov hlau molten. Nyob rau hauv cov txheej txheem no, lub melting kub, lub sij hawm thiab lwm yam tsis yog precisely tswj. Tom qab ntawd, refining yog nqa tawm, thiab refining technologies xws li lub tshuab nqus tsev refining los yog argon oxygen decarburization yog siv los tshem tawm gases thiab impurities xws li sulfur thiab phosphorus nyob rau hauv cov hlau molten, zoo heev txhim kho lub purity ntawm cov hlau molten thiab optimizing qhov zoo ntawm cov hlau. hlau.
3. Casting
Lub refined molten hlau yog tsim rau hauv billets los ntawm nruam casting los yog tuag casting. Nruam casting tuaj yeem ua tiav cov khoom tsim tau zoo thiab ua kom muaj kev ruaj ntseg ntawm billet zoo; tuag casting yog tsim rau tshwj xeeb specifications los yog me me batch ntau lawm xav tau kev pab. Tus nqi cua txias yuav tsum tau tswj nruj me ntsis thaum lub sij hawm casting txheej txheem kom tau txais cov qauv zoo tagnrho.
4. Kub dov thiab annealing
Tom qab cua sov, lub billet yog dov rau ntawm ib tug kub dov zeb los ua nws mus rau hauv thawj cov duab ntawm cov hlau. Qhov kub dov kub thiab txo qis yuav tsum raug teeb tsa raws li cov khoom siv. Tom qab ntawd, cov hlau kub dov yog annealed, feem ntau khaws cia rau hauv qhov kub thiab txias rau ib lub sijhawm, thiab maj mam txias kom tshem tawm cov kev ntxhov siab sab hauv uas tsim los ntawm cov txheej txheem kub dov, txhim kho cov plasticity thiab toughness ntawm cov khoom, thiab tsim. cov xwm txheej zoo rau kev ua haujlwm tom ntej.
5. Pickling thiab kos duab
Tom qab annealing, nto ntawm cov hlau yuav muaj oxide nplai. Cov txheej txheem pickling siv cov kua qaub kom tshem tawm cov nplai oxide thiab lwm yam khoom tsis huv los ua kom lub ntsej muag ntawm cov hlau huv. Tom qab ntawd, cov xaim pickled yog kos rau hauv txoj kab uas hla uas xav tau los ntawm lub tshuab kos duab ntawm qhov tsim nyog qhov nrawm thiab tuag loj. Thaum lub sij hawm tus txheej txheem kos duab, ntau daim duab yuav tsum tau, thiab intermediate annealing yuav tsum tau los tiv thaiv cov hlau tawg thiab xyuas kom meej qhov ntev.
6. Kev kho mob zaum kawg thiab tshuaj xyuas
Cov hlau rub tawm tau txais kev kho cua sov uas tsim nyog, xws li kev daws teeb meem, txhawm rau kho nws cov microstructure thiab kev ua tau zoo. Tom qab ntawd qhov saum npoo ntawm cov hlau hlau raug kho, xws li passivation, los txhim kho corrosion kuj. Thaum kawg, kev tshuaj xyuas tag nrho yog ua tiav, suav nrog kev tshuaj xyuas tshuaj lom neeg, tshuaj xyuas khoom vaj khoom tsev, kev ntsuam xyuas kev sib xyaw ua ke, thiab lwm yam, kom ntseeg tau tias cov khoom lag luam zoo ua tau raws li tus qauv yuav tsum tau ua ntawm UNS S32950 Duplex Stainless Hlau Hlau, thiab cov khoom tsim nyog tau ntim thiab khaws cia.
