Kev tiv thaiv -Oxidation Performance Sib txawv ntawm Cov Khoom Siv Hluav Taws Xob Ntshuam thiab Txheem
Siab - kub oxidation yog qhov tseem ceeb ua rau kev laus thiab khawb ntawm cov cua kub cua sov. Lub plhaub hlau ntawm cov khoom cua sov ua haujlwm nyob rau hauv siab - huab cua kub lossis nruab nrab ib puag ncig rau lub sijhawm ntev, thiab cov tshuaj tiv thaiv oxidation yuav inevitably tshwm sim ntawm qhov chaw. Cov txheej txheem txheej txheem txheej txheem cua sov muaj oxidation ceev ceev, xoob oxide txheej thiab yooj yim tev, ua rau maj mam thinning ntawm lub raj phab ntsa thiab zaum kawg tsis ua hauj lwm. Imported siab -qib alloy cov ntaub ntawv optimize npib tsib xee-chromium piv thiab smelting txheej txheem, ua tiav ultra- tsawg oxidation tus nqi thiab ruaj khov nto qauv ntawm qhov kub thiab txias. Kev tiv thaiv zoo heev - oxidation kev ua tau zoo ua kom ntev- lub sij hawm ruaj khov ntawm cov cua sov tso tawm ntawm cov cua sov thiab tswj xyuas qhov kub thiab txias sib piv nrog cov ntsuas kub ntsuas.
Ordinary stainless hlau cua sov raj muaj qhov tsis ruaj tsis khov alloy tivthaiv kev faib ua feem thiab siab impurity cov ntsiab lus. Nyob rau hauv ntev -lub sij hawm siab -kub oxidation, cov ntaub ntawv tuab thiab xoob oxide txheej. Cov nplais oxide no muaj cov adhesion tsis zoo thiab yooj yim rau poob nrog thermal cycling vibration thiab nruab nrab scouring. Nruam tev ntawm oxide txheej ua rau maj mam thinning ntawm lub raj phab ntsa, txo cov txheej txheem lub zog thiab siab tsis kam. Cov cheeb tsam thinning hauv zos yog qhov ua rau deformation thiab perforation nyob rau hauv thiab sab nraud siab, ua rau lub rhaub tsis ua hauj lwm.
Oxidation scaling tseem cuam tshuam rau kev hloov pauv ntawm tshav kub thiab thermal field uniformity. Loose oxide txheej tsim thermal tsis kam ntawm lub raj nplaim, cuam tshuam rau sab nraud cua sov conduction. Tsis sib npaug scaling thickness ua rau inconsistent lub zos tshav kub hloov efficiency, ua nyob rau hauv unbalanced nto kub ntawm lub rhaub. Cov khoom siv hluav taws xob thaum ntxov ua rau muaj qhov sib txawv hauv zos, ua rau tsis ruaj khov thermal teb ntawm cov khoom siv thiab cuam tshuam cov txheej txheem ntau lawm.
Imported siab -nickel-chromium alloy plhaub cov ntaub ntawv muaj cov khoom sib piv thiab ultra- cov ntsiab lus tsis zoo. The dense metal texture forms a thin and compact passivation film on the surface during high-temperature operation. Qhov ruaj khov oxide zaj duab xis no muaj zog adhesion thiab yuav tsis tev tawm nrog thermal cycling, zoo cais huab cua thiab nruab nrab yaig. Lub raj phab ntsa tuab thiab cov txheej txheem muaj zog nyob ruaj khov rau lub sijhawm ntev, zam kev laus tsis ua haujlwm los ntawm oxidation thinning.
Qhov chaw ruaj khov ntawm lub xeev ua kom zoo sib xws ntawm cov cua sov hloov mus rau lub sijhawm ntev. Tsis muaj qhov tsis sib xws thermal kuj scaling yog tsim rau ntawm lub tshuab cua sov, tswj kev kub ceev ceev hauv txhua ntu. Tag nrho cov thermal teb tso zis yog ruaj khov thiab tsis tu ncua, tsis muaj qhov sib txawv ntawm qhov kub thiab txias los ntawm oxidation scaling. Cov ntaub ntawv ntsuas kub ntsuas kub tuaj yeem cuam tshuam qhov ntsuas cua sov ntawm cov cuab yeej siv tiag tiag, kom ntseeg tau tias raug kaw thiab siv tau zoo - voj tswj qhov kub thiab txias.
Raws li cov ntaub ntawv soj ntsuam kev laus hauv kev lag luam, kev tiv thaiv kev tiv thaiv - oxidation kev pab cuam lub neej ntawm cov khoom siv hluav taws xob tuaj txawv teb chaws yog ntau dua ob npaug ntawm cov khoom lag luam zoo tib yam nyob rau hauv tib lub siab - kub ua haujlwm. Kev tiv thaiv zoo heev - kev laus ua tau zoo txo qis cov khoom siv tu ntau zaus thiab kev tsim khoom poob qis. Rau siab - kub tsis tu ncua cov khoom siv cua sov ua raws sijhawm ntev - lub sij hawm ruaj khov, cov khoom siv sib txawv txawv teb chaws yog qhov tseem ceeb ntawm kev ua haujlwm zoo thiab ruaj khov, thiab cov txheej txheem kev xaiv cov khoom siv tuaj yeem kho raws li qhov ua haujlwm kub thiab nruab nrab ib puag ncig.
