• Txo thaj tsam: Ntau dua lossis sib npaug li 50%

Cov khoom siv kho tshuab tiag tiag tuaj yeem sib txawv nyob ntawm seb yam xws li kev kho cua sov thiab kev ua haujlwm.

 

20CrMnMo, cov qauv hlau alloy, pom kev siv dav hauv ntau qhov kev lag luam vim nws cov khoom sib txawv thiab muaj peev xwm. Tsab ntawv xov xwm no yog npaj los muab kev tshawb nrhiav qhov tob ntawm cov ntawv thov sib txawv ntawm 20CrMnMo.

Hauv kev lag luam tsheb, 20CrMnMo tau ua haujlwm hauv kev tsim cov khoom tseem ceeb xws li lub zog, ncej, thiab qag. Cov hlau muaj zog thiab ua haujlwm ntev ua rau cov khoom no tuaj yeem tiv taus cov kev ntxhov siab thiab kev rov ua dua tshiab thaum lub sijhawm ua haujlwm ntawm lub tsheb, ua kom ntseeg tau tias kev ua tau zoo thiab kev pabcuam ntev dua.

Lub tshuab tsim kev lag luam tau txais txiaj ntsig zoo los ntawm 20CrMnMo. Nws yog siv rau hauv kev tsim cov khoom siv hnyav xws li crankshafts, txuas rods, thiab kis tau tus mob. Kev sib xyaw ua ke ntawm hardness thiab toughness muab los ntawm cov hlau no tso cai rau kev ua haujlwm zoo raws li qhov xav tau thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav ntxov.

Hauv thaj chaw aerospace, qhov uas cov khoom siv hnyav tseem muaj zog yog qhov tseem ceeb, 20CrMnMo pom nws daim ntawv thov hauv qee yam khoom. Nws muaj peev xwm tiv taus qhov kub thiab txias thiab cov khoom siv kho tshuab ua rau nws tsim nyog rau qhov chaw uas muaj huab cua puag ncig.

Kev tsim kho kev lag luam ua rau siv 20CrMnMo rau kev txhawb nqa tuav thiab cov khoom siv. Cov hlau lub zog thiab kev tiv thaiv rau deformation ua rau muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov tsev thiab cov vaj tse, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj seismic kev ua ub no los yog qhov twg hnyav loads.

Hauv kev lag luam roj thiab roj, 20CrMnMo yog siv rau hauv kev tsim cov khoom siv tho, twj tso kua mis, thiab cov khoom siv valve. Cov khoom siv corrosion kuj thiab lub zog txhua yam yog qhov tseem ceeb rau kev tiv thaiv qhov hnyav thiab corrosive cuam tshuam nrog roj thiab roj rho tawm thiab kev thauj mus los.

Rau kev tsim cov pwm thiab tuag, 20CrMnMo yog qhov nyiam vim nws cov cua sov ua haujlwm zoo thiab qhov ruaj khov. Nws ua rau kev tsim cov duab meej thiab nyuaj nrog cov khoom zoo sib xws, ua kom muaj txiaj ntsig zoo ntawm ntau qhov chaw.

Nyob rau hauv lub zog tsim sector, turbine shafts thiab generator Cheebtsam feem ntau suav nrog 20CrMnMo. Cov khoom siv hlau ua rau nws tuaj yeem tiv taus kev sib hloov ceev thiab kev ntxhov siab txhua yam, ua rau muaj kev ntseeg siab ntawm cov cuab yeej tsim hluav taws xob.

Ntxiv mus, 20CrMnMo yog siv nyob rau hauv kev tsim cov khoom ua si, qhov twg nws lub zog thiab lub teeb yuag yam ntxwv muaj nuj nqis. Piv txwv suav nrog cov khoom ntawm cov tsheb kauj vab ua haujlwm siab thiab cov khoom siv qoj ib ce.

Hauv kev xaus, cov khoom tshwj xeeb ntawm 20CrMnMo ua rau nws yog ib qho khoom siv tseem ceeb hauv ntau qhov kev lag luam. Nws cov ntawv thov txuas ntxiv nthuav dav thiab hloov zuj zus raws li thev naus laus zis nce qib thiab cov teeb meem tshiab engineering tshwm sim. Kev tshawb fawb tsis tu ncua thiab kev txhim kho hauv cov ntaub ntawv tshawb fawb zoo li yuav qhib qhov kev siv ntau dua rau cov hlau ntau yam no, ntxiv dag zog rau nws txoj kev koom tes rau kev tsim khoom niaj hnub thiab kev tsim vaj tsev.
