Khoom Nthuav dav

Cov khoom lag luam

Hmoov metallurgy ntsig txog kev lag luam yog siv rau kev tsim kho tsheb, kev tsim khoom siv, kev lag luam hlau, kev siv dav hlau, kev lag luam tub rog, kev ntsuas khoom, cov cuab yeej khoom siv, cov khoom siv hluav taws xob hauv tsev thiab lwm cov teb ntawm cov khoom seem tsim thiab tshawb fawb, muaj feem xyuam nrog cov khoom lag luam, tsim cov khoom lag luam, txhua yam hom hmoov ua cov khoom siv, cov khoom lag luam sintering tsim khoom.Qhov suav nrog cov kabmob, cov iav, cov cuab yeej carbide txiav, tuag, kev sib txhuam cov khoom lag luam thiab lwm yam. lwm qhov nres khub yuav tsum tau ua los ntawm hmoov hlau tshuab kev lag luam.Hauv xyoo tsis ntev los no, P / M pib qhov chaw tau dhau los ua lag luam loj tshaj plaws rau P / M kev lag luam hauv Suav. Txog 50% ntawm ntu tsheb yog P / M qhov chaw.

(1) Cov ntawv thov: (tsheb, maus taus, textile machinery, tshuab xaws tshuab, tshuab hluav taws xob, khoom siv kho vajtse.Qhov khoom siv hluav taws xob, kev siv tshuab, thiab lwm yam) cov hmoov hlau ua kom zoo nkauj (hlau tooj liab puag) qhov chaw.

(2) kev faib tawm: hmoov metallurgy ntxeem tau cov ntaub ntawv, hmoov metallurgy cov khoom siv los tiv thaiv kev sib txhuam, hmoov metallurgy txhuam cov ntaub ntawv, hmoov metallurgy cov txheej txheem ntu, hmoov metallurgy pwm cov ntaub ntawv, thiab hmoov metallurgy electromagnetic cov ntaub ntawv thiab hmoov metallurgy kub cov khoom kub, thiab lwm yam.

Yog li.From lub tsheb, lub tog maus taus nyob rau hauv tag nrho cov hmoov metallurgy qhov chaw suav rau qhov kev faib ua feem ntawm qhov nce.Koj tuaj yeem pom tias.Powder metallurgical iav yog nyob hauv txoj kev loj hlob sai ntawm tag nrho cov hmoov metallurgical qhov chaw.Yog raws li cov yam ntxwv ntawm qhov chaw faib.Gear belongs rau cov khoom siv hauv cov qauv.Qhov qhov loj ntawm cov txheej txheem hauv cov hlau tag nrho - raws qhov muaj qhov loj dua qhov ntawm lwm qhov.Qhov ntau yam thiab cov hmoov ntawm cov hmoov hlau ua kom nce hnub los ntawm hnub, thiab lawv cov ntawv thov tau. yog ua ntau thiab ntau dua.

Qhov no yog vim: 1) thaum lub iav muaj qhov nkhaus tsis khov, eccentricity, radial tiv thaiv lossis pits: thaum lub iav muaj qhov tsis xwm yeem, txoj hauv kev, lub tiaj tiaj, lub nrawm, plaub fab qhov, taper qhov; Thaum lub iav muaj tiv thaiv, zawj, qhov muag tsis pom lub qhov thiab cov pits sib txawv ntawm qhov tob hauv qhov kev taw qhia axial.Powder metallurgy cov txheej txheem yog qhov yooj yim tsim khoom thiab xav tau me lossis tsis siv tshuab ua haujlwm.General hmoov metallurgy iav nrog cov hmoov metallurgy tsim cov txheej txheem, tsuas yog xav tau tsib kauj ruam. ib qho roj siv roj.Qhov khoom siv thiab tsim khoom nrog cov khoom siv casting thiab cov khoom siv ntxiv.Tom qab lub tsheb sab nraud lub voj voog sab hauv lub voj voog ib lossis ob lub ntsej muag kawg, lub ntsej muag zawm, qhov tseem ceeb, lub zog hobbing, kev tawm tsam, kev kho cua sov, kev npau taws thiab lwm kaum txheej txheem.Yog li ntawd, thaum cov hmoov hlau hmoov txheej txheem siv rau kev tsim khoom.Hauv rau lub xeev kev ua haujlwm, khoom siv, kev ua haujlwm siab ntau, siv cov khoom siv qis dua, txuag hluav taws xob.Qhov khoom cov nqi ion txo qis dua.2) thaum ua cov iav los ntawm cov hmoov metallurgy txujci.Qhov kev siv khoom tuaj yeem ncav ntau dua 95% .Qhov no yog vim tias: A.Shape uas tuaj yeem tsim ncaj qha rau hauv qhov chaw tiav: B.Any khib ntawm kev sib cog ua ntej kev ua txhaum. .Cov tau shredded thiab rov siv dua.Qhov no tsis tuaj yeem thaum cov iav tau tsim los ntawm lwm cov tshuab machining.3) Cov reproducibility ntawm hmoov hlau metallurgy zoo heev.Because ntawm cov hmoov; Taijin iav yog tsim los ntawm pwm nias. Hauv qhov xwm txheej ib txwm siv, ib lub pwm tuaj yeem nias kaum tawm txog ntau pua txog txhiab tus iav txhawm.Qhov me nyuam los ntawm kev siv lub tshuab

Ua ntej, qhov zoo ntawm hmoov metallurgy txheej txheem

1, tuaj yeem ua cov ntaub ntawv tshwj xeeb.Material hmoov metallurgy txoj kev tuaj yeem tsim cov hlau refractory zoo li ntxiv rau cov khoom sib txuas, cov hmoov pseudo, thiab cov khoom ntxeem tau.

2, txuag cov hlau, txo cov nqi.Because hmoov metallurgy tuaj yeem raug nias rau qhov loj kawg ntawm kev cog lus, tsis tas yuav siv cov khoom siv ua cov neeg ua haujlwm.Qhov poob ntawm cov hlau tsim txoj hauv kev no tsuas yog 1 txog 5 feem pua, piv nrog 80 feem pua ​​rau kev ua.

Kev tsim cov khoom hmoov metallurgy

1, cov yam ntxwv ua tau zoo: hmoov metallurgy yog tus sawv cev ntawm cov hlau-qhov sib xyaw, yuav tsim kom muaj ntau qhov ntim ntawm cov khoom lag luam muaj txiaj ntsig, cov yam ntxwv zoo.

2, alloy siab ua tau zoo: hmoov metallurgy raug teeb tsa qauv microstructure, kev ua haujlwm yog qhov nyuaj thiab tag nrho cov ntsiab lus siab ua haujlwm zoo.

3, mixed theem tshwj xeeb alloy: hmoov metallurgy nrog kev txhim kho txheej txheem los tsim cov khoom siv dav tshwj xeeb uas muaj cov theem sib xyaw.

4, cov ntu sib xyaw: ua cov txheej txheem sib txawv thiab tsis-dav dav lossis cov khoom sib xyaw ua ke.

5. Kev npaj cov khoom purity siab.Powder metallurgy cov txheej txheem hauv cov khoom tsim cov khoom tsis yaj ntawm cov khoom, nws yuav tsis xyaw nrog lwm yam khoom coj los ntawm impurities, thiab sintering yog nqa tawm hauv lub tshuab nqus tsev thiab txo huab cua, tsis txhob ntshai oxidation thiab yuav tsis muaj kev ua qias tuaj ntawm cov khoom.Yog li ntawd, cov ntshiab ntawm cov khoom yog tus nqi siab.

6. Kev kho qhov tseeb ntawm cov khoom faib tawm.Powder metallurgy txuj ci tuaj yeem ua kom paub tseeb thiab tsis sib thooj ntawm cov khoom sib xyaw ua ke hauv kev faib ua feem.

7, huab hwm coj ntau lawm los txo nqi.Powder metallurgy yog qhov tsim nyog rau kev tsim cov khoom lag luam nrog coob tus ntawm cov khoom sib xws, xws li cov iav thiab lwm yam khoom nrog cov nqi siab, uas tuaj yeem txo tus nqi ntau lawm.
