Dab tsi yog qhov tseem ceeb ntawm kev siv hluav taws xob kub cua sov hlau? Dab tsi yog nws qhov zoo thiab qhov tsis zoo?

Hlau chromium txhuas thiab nickel chromium hluav taws xob cua sov alloys feem ntau muaj zog oxidation tsis kam. Txawm li cas los xij, vim muaj ntau cov pa roj hauv lub qhov cub, xws li huab cua, carbon cua, huab cua sulfur, hydrogen, nitrogen cua, thiab lwm yam, cov roj no muaj kev cuam tshuam rau cov khoom siv thaum kub kub. Txawm hais tias muaj ntau yam hluav taws xob cua sov alloys tau txais kev kho oxidation ua ntej tawm hauv lub hoobkas, lawv tuaj yeem ua rau cov khoom puas tsuaj rau qee yam thaum lub sij hawm kev thauj mus los, winding, installation, thiab lwm yam txheej txheem, yog li txo lawv cov kev pab cuam lub neej, kom ntev kev pab cuam lub neej, cov neeg muas zaub yuav tsum tau. mus rau kev kho mob ua ntej oxidation ua ntej siv. Txoj kev no suav nrog cua sov cov khoom siv hluav taws xob cua sov cov khoom siv hauv cov huab cua qhuav kom sov 100-200 degrees hauv qab qhov tso cai siv kub ntawm cov hlau, tuav rau 5-10 teev, thiab tom qab ntawd maj mam txias rau hauv qhov cub. .

Qhov zoo thiab qhov tsis zoo

1. Lub ntsiab zoo thiab qhov tsis zoo ntawm cov hlau chromium aluminium alloy series yog: qhov zoo: cov hlau chromium aluminium hluav taws xob cua sov alloy muaj qhov kub thiab txias, nrog kev ua haujlwm siab txog li 14{{2}0 degrees (0Cr21A16Nb, 0Cr27A17Mo2, thiab lwm yam), lub neej ntev kev pab cuam, siab nto load, zoo oxidation kuj, siab hluav taws xob resistivity, thiab tus nqi qis. Disadvantages: Feem ntau yog vim tsis tshua muaj high-temperature lub zog, nws plasticity yuav nce nrog qhov nce ntawm kev siv kub, thiab cov khoom yog nquag deformation, tsis yooj yim rau khoov thiab kho.

2. 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 lub 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 yog ib qho yooj yim los kho, nws cov hluav taws xob hluav taws xob yog siab, nws tsis yog hlau nplaum, muaj zog corrosion kuj, thiab muaj lub neej ntev kev pab cuam. Qhov tsis zoo: Vim yog siv cov khoom siv hlau nickel, tus nqi ntawm cov khoom siv no yog ob peb zaug siab dua li ntawm cov hlau chromium aluminium, thiab qhov kev siv kub yog qis dua li ntawm cov hlau chromium aluminium.
