Inconel 625 Ntawv

Lub hauv paus rau phau ntawv

Inconel 625 daim ntawv yog lub siab -}}} {%), Molybdenum (MO txog 8%), thiab ib tus naj npawb me ntawm lwm cov ntsiab lus. Nws yog dav siv nyob rau hauv cov teb tseem ceeb xws li aerospace, petorchemical, thiab lub zog nrog nws cov kub zoo thiab corrosion tsis kam. Raws li kev daws teeb meem-txhawb nqa alloy, inconel 625 ntawv qhia qhov ruaj khov zoo heev thiab kev ntseeg siab, thiab muaj zog corrosion ib puag ncig.

Zoo heev corrosion

Cov chromium hauv Inconel 625 daim ntawv tuaj yeem tsim cov yeeb yaj kiab tuab rau saum npoo ntawm alloy, siv tau zoo thaiv cov yaig ntawm kev tawm tswv yim ntawm corrosive. Qhov sib ntxiv ntawm molybdenum ntxiv txhim kho cov corrosion tsis kam ntawm alloy hauv kev txo cov xov xwm zoo xws li sulfuric acid thiab hydrochloric acid. Tus nqi corrosion ntawm inconel 625 daim ntawv hauv concentrated sulfuric acid nyob rau 90℃tsuas yog 0.1mm / uas yog qhov qis dua tus nqi corrosion ntawm dog dig stainless hlau.

Siab - kub tsis kam

Qhov loj ntawm cov khoom siv daws (xws li npib tsib), yog li cov ntaub ntawv tsis txaus ntseeg ntawm lub zog ntawm 275MPA ntawm 1000 degree, qhia tau zoo heev high - kub tsis kam.

Qeeb zog tsis kam

Ua tsaug rau qhov ruaj khov microstructure thiab zoo thiab cov ntaub ntawv lis kev sib luag thiab ua kom muaj kev ntxhov siab thiab ua tau zoo} kev ntxhov siab thiab cyclic load ib puag ncig. Cov yam ntxwv no tau txhim kho lub neej qaug zog ntawm cov khoom, uas feem ntau yog ntau dua 30% siab dua cov khoom siv zoo sib xws.

Tshuab

Kev zam

Cua sov kub:Feem ntau rhuab nruab nrab ntawm 1150 Qib rau 1230 Qib los xyuas kom paub meej cov vixental zoo thiab deformation muaj peev xwm.

Pib thiab nres forging kub: Pib funing tsawg kawg 1030℃thiab tsis muaj qis dua ntawm 930℃los tiv thaiv cov khoom embrittlement lossis tawg thaum lub sij hawm cov txheej txheem.

Forging deformation:Kho raws li cov kev cai tshwj xeeb kom lav cov microstructure zoo nkauj thiab cov neeg kho tshuab.

Dov

Preheating kub:Ranges los ntawm 1120℃rau 1160℃ua ntej dov, kom yooj yim ntawm kev deformation thaum ua tiav.

Dov Kub:Pib tsis pub tsawg tshaj 1050 degree, nrog rau nres nres kub tsis poob qis dua 930 degree, los tswj cov kev sib dhos thiab ntom ntom.

Tus nqi deformation:Pom zoo deformation rau semi - Cov khoom tiav yog 25% -30%, thaum tiav cov khoom lag luam yuav tsum tau tsawg dua 30% deformation.

Kev Kho Cua Sov

Cov kev kho cua sov regimen rau inconel 625 encompasses kev kho mob thiab daws kev kho mob ntawm lwm tus, tsom ntawm kev txhim kho cov tshuab thiab corrosion tsis kam.

Annealing:Ua kwv yees li ntawm 900℃rau undeviate sab hauv kev ntxhov siab thiab rov ua tau cov khoom siv plixicity.

Kev Kho Mob:Ua txhaum nyob rau hauv thaj tsam ntawm 930 Qib rau 1040 degree, Duration ua kom cov kev xav tau, rau Bolster Corrosion tsis kam thiab siab- lub zog.

Nto Kho

Inconel 625 daim ntawv npaj theem deg muaj feem cuam tshuam nrog ob theem: kev tu ua kom acid pickling.

Alkaline Ntxuav cov nplai thiab roj, whereas acid pickling nyob rau hauv ib lub aqueous nruab nrab txuas ntxiv purifies ntxiv rau saum npoo, tshem tawm cov peev xwm. Cov kev kho mob kom paub tseeb tias cov khoom saum npoo ua tiav thiab cov qauv sib luag, txhim kho nws cov kev thov kom zoo nkauj.

1. Cheebtsam ntawm cov tshuaj lom organic muaj cov tshuaj chlorides, tshwj xeeb tshaj yog tias yog siv acidic chloride catalysts

2. Cov zom thiab tso tsheb hlau luam rau cov pulp thiab daim ntawv kev lag luam.

3

4. Khoom siv thiab cov khoom siv rau kev siv hauv cov pa roj acidic ib puag ncig.

5. Acetic thiab acetic anhydride tshuaj tiv thaiv tshuab hluav taws xob.

6. Sulfuric acid condensers.
