B. Forged hlau qhov chaw

1. Qhov zoo ntawm forging:

Hloov cov particle ntws ntawm cov khoom kom nws ntws nyob rau hauv cov duab ntawm ib feem.

Tsim cov khoom uas muaj zog dua lwm cov txheej txheem tsim khoom.Forged qhov chaw yog heev haum rau siv nyob rau hauv txaus ntshai los yog tsis tshua muaj teeb meem, xws li gears nyob rau hauv lub tsheb cav.

Nws tuaj yeem ua rau ntau yam duab.

Muaj peev xwm tsim qhov loj heev.

Tus nqi pheej yig piv rau mechanical processing.

2. Disadvantages ntawm forging:

Tsis muaj kev tswj hwm ntawm microstructure.

Muaj kev xav tau ntau dua rau kev ua haujlwm thib ob, uas ua rau tus nqi thiab xa sijhawm ntawm qhov project.

Nws yog tsis yooj yim sua los tsim ntxeem tau bearings, cemented carbides los yog sib xyaw hlau qhov chaw.

Yog tsis muaj machining, qhov me me nrog cov qauv tsim tsis tuaj yeem tsim

Pwm ntau lawm yog kim, ua rau kev lag luam ntawm luv luv ntau lawm undesirable.

3. Yog tias koj xav ntsuas qhov zoo thiab qhov tsis zoo ntawm forging thiab hmoov metallurgy, nws yuav txhais tau tias koj tab tom nrhiav kev tsim khoom uas tuaj yeem ua tiav cov nqi zoo tshaj plaws.Qhov ntau koj saib ntawm txhua tus txheej txheem, qhov ntau koj yuav pom tias nyob ntawm koj qhov project qauv.Forging yog qhov zoo hauv qee qhov xwm txheej, thaum PM yog qhov zoo hauv lwm tus.Honestly, nws nyob ntawm seb koj xav ua kom tiav.Nrog rau kev nce qib ntawm thev naus laus zis thiab txheej txheem, hmoov metallurgy thev naus laus zis tau tsim los ntawm leaps thiab ciam teb.Tam sim no koj tuaj yeem ua tej yam zoo kawg nkaus nrog cov hmoov hlau-saib seb cov tuam txhab kub kub sintering ua dab tsi.Qee zaum, tsuas yog nce qhov kub ntawm sintering los ntawm 100 ° txog 300 ° F tuaj yeem tsim cov txiaj ntsig zoo dua hauv cov hauv qab no: lub zog, cuam tshuam lub zog, thiab lwm yam.

Hauv qee qhov chaw, forging yog ib qho kev daws teeb meem zoo.Nyob rau hauv no hais txog, tsis muaj leej twg yuav sai sai no yuav tsim steel I-beams los ntawm hmoov hlau los yog crowbars.Tab sis thaum nws los txog rau qhov me me nrog cov qauv tsim, hmoov metallurgy tau eclipsed forging.Raws li peb nkag mus rau yav tom ntej ntawm cov khoom tsim khoom (xws li lub tshuab hluav taws xob hauv kev tsim tsheb evolving), hmoov metallurgy yuav ua lub luag haujlwm tseem ceeb.Thaum cov khoom xws li kev them taus, kev tsim khoom siab, thiab cov hlau sib xyaw ua ke, PM yog qhov tseeb rau yav tom ntej.Txawm hais tias forging tuaj yeem muab cov cuab yeej zoo heev, nws yuav tsum tau them tus nqi poob qis piv nrog cov hmoov hlau tsoos.Siv cov ntaub ntawv thiab cov txheej txheem niaj hnub no, cov khoom siv hmoov hlau tuaj yeem muab qhov kev ua tau zoo ntawm koj daim ntawv thov ntawm tus nqi qis heev.
