Rings thiab dov cov ntsiab lus feem ntau yog ua los ntawm cov pa roj carbon siab chromium bearing steel. Feem ntau cov bearings siv CCr15, thiab CCr15SiMn nrog zoo hardenability yog siv rau bearing rings nrog loj cross-section thiab dov ntsiab nrog loj diameters. High-carbon chromium bearing steel yog tag nrho cov hlau tawv tawv, thiab nws qhov chaw thiab cov tub ntxhais tuaj yeem ua kom tawv, yog li nws yog cov khoom siv zoo tshaj plaws rau cov kabmob dov.
Vim muaj kev siv ntau zaus, qee cov bearings yuav tsum muaj cov khoom siv tshwj xeeb, xws li kev cuam tshuam, kub tsis kam, corrosion kuj thiab lwm yam.
Carburized bearing steel feem ntau yog siv rau lub nplhaib thiab dov cov kabmob ntawm cov kabmob uas raug cuam tshuam los ntawm kev thauj khoom lossis cov kabmob loj thiab cov kabmob loj ntxiv thaum ua haujlwm. Carburizing bearing steel yog carburized nyob rau hauv qhov tsim nyog qhov tob ntawm txheej txheej ntawm chromium-molybdenum steel, chromium-nickel-molybdenum steel los yog chromium-manganese-molybdenum steel, yog li ntawd nws muaj ib tug ntom qauv thiab tsim ib tug hardened txheej, thaum lub hardness. ntawm qhov nruab nrab yog qhov tsawg thiab muaj qhov zoo ntawm cov ntsiab lus toughness, vim qhov kev ua tau zoo ntawm carburized bearing steel, nws lub neej suav yog tib yam li cov pa roj carbon siab chromium bearing steel.
Cov kabmob uas ua haujlwm ntawm qhov kub thiab txias yog ua los ntawm cov kabmob kub-kub nrog cov cua kub zoo, thiab cov kabmob uas raug corrosive media thaum ua haujlwm yog ua los ntawm cov hlau tsis muaj steel.
Nws yog ib qho tsim nyog sau cia tias kev huv ntawm cov kabmob steel, qhov siab dua qhov kev huv, qhov tsis muaj hlau tsis sib xws, cov pa oxygen tsawg dua, lub neej ntev dua, lub tshuab nqus tsev degassing lossis lub tshuab nqus tsev tuaj yeem ua tau raws li qhov yuav tsum tau ua. Bearings yuav tsum muaj kev ntseeg siab yuav tsum tau ua los ntawm electroslag remelted steel.
