Qhov chaw ua haujlwm ntawm hluav taws xob cua sov hlau

Qhov chaw ua haujlwm ntawm hluav taws xob cua sov hlau

Cov hluav taws xob cua sov hlau nws tus kheej muaj qee qhov kev tiv thaiv corrosion, tab sis nyob rau hauv qhov chaw kub kub, qhov corrosion kuj ntawm hluav taws xob cua sov hlau yuav txo. Nyob rau tib lub sijhawm, thaum hluav taws xob cua sov xaim ua haujlwm nyob rau hauv qhov chaw corrosive, qhov kub siab tshaj plaws ua haujlwm

Cov degree kuj yuav cuam tshuam. Yog li ntawd, thaum xaiv ib qho hluav taws xob cua sov xaim, nws yuav tsum tau xav txog nws qhov chaw ua haujlwm, xws li carbon cua, huab cua sulfur, nrog rau hydrogen thiab nitrogen cua.

Cov hluav taws xob cua sov xaim muaj kev tiv thaiv kev kho mob thaum lub sijhawm tsim khoom, tab sis vim muaj ntau yam xws li kev thauj mus los thiab kev teeb tsa, tej zaum yuav muaj qee qhov kev puas tsuaj rau hluav taws xob cua sov xaim ua ntej siv. Lub sijhawm no, hluav taws xob cua sov xaim tuaj yeem ua ntej oxidized,

Lub hwj chim ntawm cov cuab yeej nruab nrog hluav taws xob cua sov xaim hauv huab cua qhuav kom txog thaum qhov kub nce mus txog 100 degree txog 200 degree hauv qab qhov siab tshaj plaws ua haujlwm kub, tuav rau 5 mus rau 10 teev, thiab tom qab ntawd maj mam txias.

1, Cov qauv khoom, kev ua tau zoo, thiab kev siv cov lus piav qhia (Cov Khoom Taw Qhia)

1. Hluav taws xob cua sov alloys: Raws li lawv cov ntsiab lus sib txawv ntawm cov tshuaj lom neeg thiab cov qauv tsim, lawv tuaj yeem muab faib ua ob pawg: ib qho yog cov hlau chromium aluminium alloy series, thiab lwm yam yog cov nickel chromium alloy series, uas yog siv los ua hluav taws xob cua sov. cov ntaub ntawv

Txhua tus muaj nws tus kheej zoo thiab yog dav siv.

Cov ntawv thov tseem ceeb: Cov khoom siv cua sov thiab cov cuab yeej siv hluav taws xob rau cov tshuab metallurgical, kev kho mob, tshuaj, ceramic, hluav taws xob, hluav taws xob, iav, thiab lwm yam.

2. Qhov zoo thiab qhov tsis zoo ntawm cov hlau chromium aluminium alloy series: Qhov Zoo: Cov hlau chromium aluminium hluav taws xob cua sov alloy muaj qhov kub thiab txias, nrog rau qhov kub siab tshaj plaws ntawm kev khiav hauj lwm txog li 1400 degrees , xws li 0Cr21A16Nb, 0Cr27A17Mo2, thiab lwm yam

) Lub neej ua haujlwm ntev, siab load, zoo antioxidant kev ua tau zoo, siab tiv taus, thiab tus nqi qis. Disadvantages: Feem ntau yog vim tsis muaj high-temperature lub zog, lub plasticity nce raws li qhov kev siv kub nce, thiab cov khoom yog nquag deformation,

Tsis yooj yim rau khoov thiab kho.

3. Lub ntsiab zoo thiab qhov tsis zoo ntawm cov nickel chromium hluav taws xob cua sov alloy series yog: qhov zoo: qhov kub thiab txias zog yog siab dua li ntawm cov hlau chromium aluminium, nws tsis yooj yim rau deform nyob rau hauv qhov kub kub siv, nws cov qauv tsis yooj yim hloov, nws cov plasticity zoo, nws yooj yim kho, thiab nws cov hluav taws xob hluav taws xob yog siab,

Tsis muaj hlau nplaum, muaj zog corrosion kuj, kev pab lub neej ntev, thiab lwm yam Disadvantages: Vim siv cov khoom siv tsis tshua muaj nickel hlau, tus nqi ntawm cov khoom siv no yog ob peb zaug siab dua li ntawm cov hlau chromium aluminium, thiab kev siv kub yog qis dua. uas yog hlau chromium aluminium.
