Tau ntev, engineers thiab cov neeg yuav khoom muaj peev xwm tau sib piv cov hmoov metallurgy nrog cov txheej txheem sib tw.Raws li cov hmoov hlau qhov chaw thiab forged qhov chaw, zoo li lwm yam kev sib piv ntawm kev tsim cov txheej txheem, nws pab kom nkag siab qhov zoo thiab qhov tsis zoo ntawm txhua txoj kev.Hmoov metallurgy (PM) muaj ntau yam zoo uas koj yuav tsum xav txog - qee qhov pom tseeb, qee qhov tsis muaj ntau.Tau kawg, qee zaum, forging kuj yog ib qho kev xaiv zoo.Cia peb saib cov kev siv zoo tshaj plaws thiab kev siv cov hmoov hlau thiab forged qhov chaw:
1. hmoov hlau thiab forgings
Txij li thaum los ua mainstream, hmoov metallurgy tau dhau los ua ib qho kev daws teeb meem rau kev tsim cov khoom me me hauv ntau qhov xwm txheej.Lub sijhawm no, koj tuaj yeem sib cav hais tias ntau cov castings uas tuaj yeem hloov tau los ntawm PM tau hloov.Yog li, dab tsi yog qhov txuas ntxiv rau kev siv tag nrho cov hmoov hlau?Yuav ua li cas yog forged qhov chaw?Cov lus teb yog tshwj xeeb heev rau koj daim ntawv thov.Cov khoom sib txheeb ntawm ntau yam khoom siv forging (forgings yog ib feem ntawm lawv), thiab tom qab ntawd qhia txoj haujlwm ntawm cov hmoov hlau uas haum rau kev piav qhia.Qhov no tau tsim lub hauv paus rau PM tam sim no, thiab qhov tseem ceeb tshaj, qhov ua tau PM.Saib qhov twg 80% ntawm cov hmoov hlau kev lag luam nyob ntawm cov cam khwb cia hlau, phosphor bronze, thiab lwm yam. Txawm li cas los xij, hmoov hlau qhov chaw tam sim no yooj yim dua cov khoom cam khwb cia hlau.Hauv luv luv, yog tias koj npaj yuav siv cov hlau-tooj liab-carbon los tsim cov khoom, ces hmoov metallurgy yuav tsis yog rau koj.Txawm li cas los xij, yog tias koj tshawb fawb cov ntaub ntawv thiab cov txheej txheem ntau dua, PM tuaj yeem muab kev ua haujlwm uas koj xav tau ntawm tus nqi qis dua li forgings.
2. Cia peb ua tib zoo saib qee qhov zoo thiab qhov tsis zoo ntawm cov hmoov hlau thiab forged qhov chaw:
A. Hlau hmoov metallurgy qhov chaw
1. Qhov zoo ntawm hmoov metallurgy:
Cov khoom tuaj yeem tsim nrog cov ntaub ntawv uas tuaj yeem muab kev pabcuam kub thiab ua haujlwm siab, thiab tus nqi txo.Xav txog cov hlau tsis muaj steel, uas yuav raug kub siab hauv cov tshuab tso pa tawm, thiab lwm yam.
Muaj peev xwm tswj tau cov khoom tsim tau siab ntawm qhov chaw, txawm tias qhov nyuaj.
Vim lub net shapeability ntawm hmoov metallurgy, feem ntau ntawm lawv tsis xav tau machining.Tsawg dua kev ua haujlwm thib ob txhais tau tias tus nqi zog qis dua.
Kev siv cov hmoov hlau thiab sintering tuaj yeem ua tiav kev tswj hwm qib siab.Qhov no tso cai rau kev kho kom zoo ntawm electromagnetic zog, ntom, damping, toughness thiab hardness.
Kub kub sintering zoo heev txhim kho lub zog tensile, khoov qaug zog thiab cuam tshuam lub zog.
2. Disadvantages ntawm hmoov metallurgy:
PM cov khoom feem ntau muaj qhov txwv me me, uas tuaj yeem ua rau qee qhov tsim tsis tuaj yeem tsim.Cov xovxwm loj tshaj plaws hauv kev lag luam no yog kwv yees li 1,500 tons.Qhov no txwv qhov loj me me rau thaj tsam ntawm thaj tsam ntawm 40-50 square inches.Ntau qhov tseeb, qhov nruab nrab xovxwm loj yog nyob rau hauv 500 tons, yog li thov ua ib txoj kev npaj rau koj txoj kev loj hlob.
Cov khoom uas muaj cov duab nyuaj kuj yuav nyuaj rau kev tsim khoom.Txawm li cas los xij, cov kws tshaj lij hlau qhov chaw tsim khoom tuaj yeem kov yeej qhov kev sib tw no thiab txawm tias pab koj tsim.
Feem ntau tsis muaj zog los yog stretchable li cam khwb cia hlau los yog forged qhov chaw.
