Lub hom phiaj tseem ceeb ntawm cov cua kub cua sov yog dab tsi? Dab tsi yog nws qhov zoo thiab qhov tsis zoo?
Hlau-chromium txhuas, npib tsib xee-chromium hluav taws xob cua sov alloy nws oxidation kuj feem ntau muaj zog, tab sis vim hais tias lub cub tawg muaj ntau yam gases, xws li cua, carbon cua, sulfur cua thiab hydrogen, nitrogen cua, thiab lwm yam. cuam tshuam rau cov khoom siv nyob rau hauv qhov kub thiab txias, txawm hais tias muaj ntau hom hluav taws xob alloys yog oxidation kev kho mob ua ntej tawm hauv lub Hoobkas, tab sis nyob rau hauv kev thauj mus los, winding, installation thiab lwm yam kev sib txuas yuav ua rau cov khoom puas tsuaj rau qee yam, thiab txo cov kev pab cuam lub neej. Txhawm rau txuas ntxiv lub neej kev pabcuam, cov neeg siv khoom yuav tsum tau ua ntej oxidize ua ntej siv, Txoj kev yog kom sov cov khoom siv hluav taws xob hauv cov huab cua qhuav mus rau 100-200 degrees qis dua qhov tso cai siv kub ntawm cov hlau, kom sov rau 5-10 teev, thiab tom qab ntawd maj mam txias nrog lub qhov cub.
Pros thiab cons
1. Qhov zoo thiab qhov tsis zoo ntawm cov hlau-chromium-aluminium alloy series: qhov zoo: hlau-chromium-aluminium hluav taws xob cua sov alloy muaj qhov kub thiab txias, siv kub txog li 1400 degrees, (0Cr21A16Nb, 0Cr27A17Mo2, thiab lwm yam), lub neej ntev kev pab cuam, siab nto load, zoo oxidation kuj, siab resistivity, pheej yig tus nqi, thiab lwm yam Disadvantages: tsis tshua muaj kub lub zog, nrog rau kev siv kub nws plasticity yuav loj dua, cov khoom yog ib qho yooj yim rau deform, tsis yooj yim rau khoov thiab kho.
2. Lub ntsiab zoo thiab qhov tsis zoo ntawm nickel-chromium hluav taws xob cua sov alloy series: qhov zoo: qhov kub thiab txias zog yog siab dua hlau chromium aluminium, tsis yooj yim rau deform nyob rau hauv kub siv, nws cov qauv tsis yooj yim hloov, plasticity zoo dua, yooj yim. los kho, nws cov emissivity siab, uas tsis yog-sib nqus, muaj zog corrosion kuj, kev pab lub neej ntev, thiab lwm yam Disadvantages: Vim yog siv cov nickel hlau cov ntaub ntawv, tus nqi ntawm no series ntawm cov khoom yog ob peb zaug siab tshaj li ntawm cov hlau chromium txhuas, thiab kev siv kub yog qis dua li ntawm cov hlau chromium aluminium.
