Ib tug. Raws li kev ua haujlwm ntawm cov kabmob
1. Kev ua haujlwm kub
Bearings kev khiav hauj lwm ntawm chav tsev kub yog ua los ntawm chrome bearing steel. Chromium bearing steels tseem siv tau rau kev ua haujlwm kub siab tshaj 150 ° C thiab qis dua 250 ° C, tab sis raug rau kev kho kub tshwj xeeb (yuav tsum tau npau taws ntawm 200 ° C lossis 300 ° C).
2. Qhov ntau ntawm cov khoom thauj
Bearings nrog lub zog muaj zog ntim feem ntau tsis yog ua los ntawm chrome bearing steel, thiab lawv feem ntau yog ua los ntawm cov cuab yeej zoo nkauj uas muaj txiaj ntsig steel, kev cuam tshuam los tiv thaiv cov cuab yeej steel lossis quenched thiab tempered steel.
3. Hu rau nruab nrab
Bearings siv nyob rau hauv xov xwm corrosive yuav tsum yog ua los ntawm kev txhim kho corrosion-resistant hlau lossis alloy steel nrog zoo corrosion kuj.
ob. Raws li hom qauv ntawm kev coj tus kheej
Cov qauv ntawm cov kabmob qhov chaw yog ntau cov nyom. Piv txwv li, thaum lub nplhaib sab nraud yog nruab nrog lub tav, thiab lub nra hnyav rau kev thauj khoom yog qhov yuav tsum tau ua, cov hlau carburized nrog kev ua haujlwm zoo yuav tsum siv; lub nplhaib sab nrauv ntawm dov koob tuaj yeem tuaj yeem ua tau ntawm 08 thiab 10 cov pa roj carbon tsis tshua muaj steel (zoo plasticity (Haum rau cov khaub thuas txias); cov kabmob sib koom siv nyob rau hauv lub viav vias mechanism lossis kev siv lub tshuab ua haujlwm tuaj yeem raug txias txias los ntawm kev siv GCr15, 9Cr18, 9Cr8Mo thiab alloy qauv hlau nrog zoo heev txias yas deformation zog.
peb. Xaiv raws cov kabmob lub neej qaug zog thiab yuav tsum tau kev cia siab
Ua kom lub cev qaug zog lub neej thiab kev ntseeg tau yog nyob ntawm qee yam ntawm kev coj dawb huv thiab kev sib txawv ntawm cov hlau. Rau kev siv dav dav, siv cov khoom siv zoo tib yam steel smelted hauv acid qhib hearth rauv lossis alkaline hluav taws xob ua kom sov. Nrog cov kev txhim kho tsis tu ncua ntawm cov txheej txheem smelting, cov txheej txheem sib txawv tshiab xws li kev hloov kho tam sim no, lub tshuab nqus tsev smelting, thiab cov hluav taws xob cov nplais hluav taws xob tau tsim, thiab cov kabmob ua los ntawm cov kabmob steel ua los ntawm cov qauv saum toj no muaj lub neej zoo sib xws. Haum rau cov kabmob nrog cov kev xav tau tshwj xeeb rau kev ua kom lub neej qaug zog thiab muaj kev ntseeg siab, xws li qag qag rau cov tsheb ciav hlau, lub dav hlau cav ntxaiv cov kabmob thiab cov kab ke navigation.
