Hmoov metallurgy cov khoom siv hauv kev lag luam tsheb

Cov hmoov metallurgy cov khoom siv hauv tsheb yog cov khoom siv nrog cov ntawv pov thawj science thiab cov thev naus laus zis, uas tuaj yeem txo qhov hnyav ntawm lub tsheb thiab txo tus nqi tsim khoom, thiab muaj qhov zoo ntawm kev ua kom tau zoo ntawm kev lag luam tsheb.
Tam sim no, muaj ntau dua 400 hom hmoov metallurgy qhov chaw siv hauv tsheb hauv ntiaj teb.

Raws li kev ua kom zoo li qub kawg tsim cov tshuab thev naus laus zis, hmoov metallurgy muaj qhov zoo hauv kev txuag hluav taws xob, khoom siv txuag, kev tiv thaiv ib puag ncig, kev lag luam, kev ua haujlwm siab thiab ntau lwm yam, thiab tau maj mam paub los ntawm ntau qhov kev lag luam.

Paub thiab siv dav; Tshwj xeeb tshaj yog daim ntawv thov thiab kev tsim kho nrawm ntawm tsheb hlau hmoov tsheb cov khoom lag luam tau txhawb cov hmoov metallurgy kev lag luam mus rau kev ceev ceev ntawm kev txhim kho.
Txhawm rau tshawb nrhiav cov ntawv thov tshwj xeeb thiab kev txhim kho ntawm hmoov hlau tshuab thiab khoom lag luam hauv kev lag luam tsheb, tus neeg nug tau tham nrog xibfwb Han fenglin, tus kws pab tswv yim ntawm cov hmoov hlau ua lag luam kev tshaj lij ntawm Tuam Tshoj machinery feem ntau cov chaw lag luam koom nrog.

Tuam Tshoj muaj peev xwm zoo rau kev thov thoob ntiaj teb

Tus xibfwb Han qhia txog kev ua kom cov hmoov hlau yog ua raws li cov hmoov hlau ua cov khoom siv, nrog cov ntawv sau - sintering tsim cov khoom lag luam ntawm cov hlau tshiab tsim kev siv technology.1940, Tebchaws Asmeskas

Lub tuam txhab tsheb loj tau hloov tag nrho cov roj twj tso kua mis iav kom hmoov hmoov metallurgy, txij ntawd los ntawm hmoov hlau metallurgy cov yam ntxwv coj hauv paus hauv kev lag luam tsheb.

Raws li cov ntaub ntawv, nyob rau xyoo 2006, tag nrho cov khoom ntawm hmoov metallurgy qhov chaw hauv Suav teb yog 78.03 lab tons, ntawm cov khoom tsim tawm ntawm hmoov metallurgy qhov chaw rau lub tsheb tau txog 28.877 lab tons. Ntxiv rau,

Hais txog qhov hnyav nruab nrab ntawm PM cov khoom siv hauv cov tsheb me me (suav nrog tsheb), qhov hnyav nruab nrab ntawm PM cov khoom siv hauv tsheb hauv tsheb yog 3.97 kg hauv 2006, piv nrog nyob rau Nyij Pooj

8.7kg, piv nrog 19.5kg hauv North America. Ntxiv rau, qhov kev lag luam tsheb tam sim no qhib rau kev txhim kho hmoov metallurgy qhov chaw rau daim ntawv thov ntu, feem ntau cav qhov chaw ntawm 16 ~ 20 kg, nce mus nce los

Cov ntu ceev yog 15 ~ 18 kg, ntu ntu nres yog 8 ~ 10 kg, lwm qhov yog 7 ~ 9 kg.Nws tuaj yeem pom tau tias Tuam Tshoj muaj kev lag luam zoo rau kev tsim hmoov metallurgy pib qhov.

Hmoov metallurgy qhov chaw tuaj yeem txo tus nqi thiab qhov hnyav

Hais txog kev txhim kho thiab cov xwm txheej tam sim no ntawm cov hmoov hlau metallurgy nws pib qhov chaw ntau lawm, xibfwb Han hais tias cov hmoov metallurgy qhov chaw siv hauv kev tsim khoom lag luam feem ntau yog cov roj-cov kabmob hlau roj thiab cov hmoov txhuam.

Metallurgical cov khoom ntu, qhov qub yog tsuas yog tsim los ntawm 90Cu-10Sn bronze, tom kawg yog qhov pib ua los ntawm cov hlau hmoov ua cov khoom siv yooj yim.

Cov hauv qab no yog qee cov piv txwv ntawm PM technology kev siv: A PM 64 toothed force extractor tsav lub iav uas raug nqi kwv yees li 40% tsawg dua qhov chaw machined los ntawm hlau, thiab

Thiab cov iav hniav tsis tas yuav ua cov kev ua tom ntej; Lub hmoov hlau metallurgy tsheb sib tsoo phau ntawv synchronizer ntiv nplhaib, piv nrog cov pa hluav taws xob ntau ntawm lub nplhaib synchronizer, tuaj yeem txo tus nqi ntawm 38%; Ib hom

Lub zog loj kawg ntawm cov hmoov metallurgy composite planetary iav ncej yog 40% siab dua qhov ntawm cov cam khwb cia hlau txiav workpiece, thaum tus nqi txo los ntawm ntau dua 35% ...

Raws li tuaj yeem pom los ntawm ob yam ntawm PM qhov uas tau yeej ntau yam khoom plig, tsawg kawg yog peb ntawm lawv tau ua nrog kev xaiv cov compaction technology thiab ob ntawm lawv yog tsim nrog sov nias tshuab

Kev tsim khoom, 6 hom ntawm cov ntu muaj li ntawm ntau dua 2 qhov sib txawv, hauv kev sib xyaw ntawm cov ntu ntawm feem ntau yog muaj 18 hmoov metallurgy qhov chaw.Professor Han tau hais tias, qhov no

Qee qhov khoom muaj txiaj ntsig qhia tau tias PM qhov chaw tsis tuaj yeem tsuas yog hloov seem hlau qhov chaw, forged steel qhov chaw, txiav workpiece, txuag kev ua haujlwm, khoom siv, txuag hluav taws xob, txo tus nqi ntau lawm, tab sis kuj tuaj yeem txo qis

Qhov hnyav ntawm qhov yuav ua tau zoo rau lub teeb taws ntawm lub tsheb.Qhov tseem ceeb tshaj, kev loj hlob ntawm hmoov metallurgy Cheebtsam, cim tias qee qhov chaw tuaj yeem tsim cov hmoov metallurgy tshuab, nrog

Ib qho tseem ceeb ntawm kev siv tshuab thiab kev lag luam.
Hmoov metallurgy yog "ntsuab" kev tsim khoom siv tshuab

Txog tam sim no, hmoov metallurgy tau lees paub tias yog lub tshuab ntsuab thiab ruaj khov hauv kev lag luam.Qhov no hais txog, xibfwb Han los ntawm cov hmoov metallurgy muaj nuj nqi muaj nuj nqi, cov ntaub ntawv tuaj yeem tuav tau

Kev ruaj khov, lub zog thev naus laus zis, khoom siv kom ruaj khov, kev muaj peev xwm nyob ib puag ncig, kev ua haujlwm ntev, kev txhawb nqa tus nqi zoo thiab lwm yam yog qhia.

Piv txwv, nyob rau hauv qhov chaw ntawm kev ua haujlwm kom ruaj khov, hmoov metallurgy muaj qhov siab kawg qhov kev ua kom muaj peev xwm thiab kev siv cov khoom siv, uas tuaj yeem ua rau tag nrho cov kev siv hluav taws xob tsawg dua.Qhov piv nrog cov khoom siv tes ua ib txwm ua (kev ua haujlwm kub
+ kev ua haujlwm txias) casting los yog forging + txiav ua piv nrog cov hmoov hlau ua cov txheej txheem tsim cov khoom lag luam ib qho tsuas yog xav tau siv ob peb txheej txheem, tuaj yeem ua tiav cov txheej txheem ntau dua, ntau dua.
Lwm yam paj ntaub.

Hais txog kev ua kom ruaj khov ntawm cov khoom siv, qhov kawg ua lub peev xwm ntawm PM yog nws qhov txiaj ntsig tseem ceeb.Piv txwv li, txhawm rau tsim ib qho hniav, qhov txheej txheem kev txiav ua tiav yuav muaj txog 40% Cov ntaub ntawv dhau los ua daim tawv nyias, thiab 85% ntawm tag nrho cov hmoov siv nyob rau hauv cov hmoov metallurgy yog tsim los ntawm cov khoom siv rov ua dua tshiab.Hauv cov txheej txheem ntau lawm ntawm hmoov metallurgy qhov chaw, txhua cov txheej txheem Cov khib nyiab pov tseg feem ntau yog 3% lossis tsawg dua, thiab kev siv cov khoom siv tuaj yeem ncav cuag 95%.

Hais txog lub zog kev ua kom ruaj khov, cov txheej txheem tsim khoom siv yuav tsum tau muaj ntau cov cua kub thiab rov ua dua tshiab los ua kom tau.Thaum hlau lossis hlau hmoov ua los ntawm atomization,

Tsuas yog ib qho smelting ntawm cov khoom seem xwb, thiab tag nrho lwm cov kev ua haujlwm kub yog ua tiav ntawm qhov ntsuas kub hauv qab melting qhov taw tes, uas tsis tsuas yog txuag lub zog, tab sis kuj tseem ua rau zaum kawg
Thiab qhov tsim ntawm qhov yuav tsum tau ua cov khoom muaj zog, kev ua haujlwm ntawm lub tshuab ua haujlwm.Yog piv rau kev siv tus nqi ntawm cov hlau cov txheej txheem cov ntaub ntawv, nws pom tias lub zog yuav tsum tau ua hmoov hmoov metallurgy qhov chaw yog forging -
Plaub caug-plaub feem pua ​​ntawm cov khoom siv machined.

Hais txog kev tiv thaiv ib puag ncig, vim muaj cov yam ntxwv ntawm qhov kawg tsim muaj peev xwm ntawm hmoov metallurgy, feem ntau, cov seem tau ua rau cov khoom tiav tom qab ua txhaum, uas tuaj yeem ntim

Cov khoom xa tuaj, xa tawm.Thaum feem ntau, qhov kev txiav cov roj siv hauv kev ua cov khoom PM yog qhov tsis muaj txiaj ntsig, thiab cov pa phem raug tso tawm los ntawm cov chaw xws li dej txias yog qhov me me

Qhov tsawg dua.Hauv piv nrog rau lwm cov txheej txheem tsim, cov hmoov hlau ntawm kev lag luam qhov chaw muaj kev puas tsuaj ib puag ncig me me.

Nyob rau tam sim no, cov hmoov hlau metallurgy qhov chaw tau yog qhov tseem ceeb ntawm qhov chaw hauv kev lag luam tsheb.Thaum yav tom ntej, Suav teb loj yuav maj mam dhau los ua lub ntiaj teb chaw loj tshaj plaws ntawm hmoov metallurgy tsheb qhov chaw
