Qhov zoo ntawm cov txheej txheem hmoov metallurgy

1, feem ntau ntawm cov hlau refractory thiab lawv cov tebchaw, cov khoom cuav, cov ntaub ntawv ntxeem tau tsuas yog tsim los ntawm cov hmoov metallurgy txoj kev.

2, vim hais tias cov hmoov metallurgy txoj kev tuaj yeem raug nias rau hauv qhov loj me me ntawm qhov compaction, tsis muaj lossis me me rau kev ua haujlwm tom ntej, nws tuaj yeem txuag tau hlau zoo heev, txo cov nqi khoom.Qhov poob ntawm cov hlau hauv kev tsim cov khoom los ntawm cov hmoov metallurgy. txoj kev tsuas yog 1-5%, thaum qhov poob ntawm cov hlau hauv kev tsim cov khoom los ntawm cov txheej txheem casting zoo tib yam yuav siab li 80%.

3, vim hais tias cov hmoov metallurgy txheej txheem hauv cov txheej txheem tsim khoom tsis yaj cov khoom, nws tsis ntshai ntawm kev sib xyaw nrog cov impurities coj los ntawm crucible thiab deoxidizer, thiab sintering feem ntau yog nqa tawm hauv lub tshuab nqus tsev thiab txo qhov cua, tsis ntshai oxidation. , thiab yuav tsis muaj kuab paug rau cov khoom siv, nws muaj peev xwm ua kom cov ntaub ntawv purity siab.

4, hmoov metallurgy txoj kev tuaj yeem ua kom ntseeg tau qhov tseeb thiab qhov sib xws ntawm cov khoom muaj pes tsawg leeg ratio.5, hmoov metallurgy yog tsim rau kev tsim cov khoom zoo ib yam thiab ntau cov khoom, tshwj xeeb tshaj yog iav thiab lwm yam khoom siv siab ua cov nqi, nrog hmoov metallurgy. kev tsim khoom tuaj yeem txo tus nqi ntau lawm.

Cov txheej txheem yooj yim ntawm hmoov metallurgy txheej txheem yog

1, kev npaj ntawm raw khoom hmoov.Tam sim no pulverizing txoj kev yuav roughly muab faib ua ob pawg: mechanical thiab physico-chemical.Cov txheej txheem yuav muab faib ua: mechanical crushing thiab atomization method; Lub cev thiab tshuaj txoj kev yog ntxiv muab faib ua electrochemical corrosion. txoj kev, txo txoj kev, tshuaj txoj kev, txo-tshuaj txoj kev, vapor deposition txoj kev, kua deposition txoj kev thiab electrolysis txoj kev.Qhov feem ntau siv txoj kev yog txo, atomization thiab electrolysis.

2. Cov hmoov sib sau ua rau cov duab uas xav tau ntawm qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob - siab molding.Pressure molding yog feem ntau siv molding.

3. Sintering ntawm billet.Sintering yog cov txheej txheem tseem ceeb hauv cov hmoov metallurgy.Qhov kawg ntawm lub cev thiab cov khoom siv yog tau los ntawm sintering lub compacted dawb paug tom qab sib sau.Sintering muab faib ua chav tsev sintering thiab multi-tivthaiv sintering.Lub sintering kub yog qis dua qhov melting point ntawm cov hlau thiab alloy siv rau cov khoom theem sintering ntawm chav tsev system thiab multi-component system.Rau cov kua theem sintering ntawm lub multi-component system, sintering kub feem ntau qis dua lub melting point ntawm refractory tivthaiv, tab sis siab tshaj qhov melting point ntawm fusible tivthaiv.Ntxiv rau cov sintering zoo tib yam, muaj xoob sintering, yaj leaching txoj kev, kub nias txoj kev thiab lwm yam tshwj xeeb sintering txheej txheem.

4. Kev ua tiav tom qab ua tiav ntawm cov khoom.Cov kev kho mob tom qab sintering tuaj yeem siv rau ntau txoj hauv kev raws li qhov sib txawv ntawm cov khoom, xws li kev ua tiav, immersion, machining, kev kho cua sov thiab electroplating. Tsis tas li ntawd, nyob rau hauv xyoo tas los no, Qee cov txheej txheem tshiab xws li dov thiab forging kuj tau siv rau kev ua cov hmoov hlau metallurgy tom qab sintering, thiab ua tiav cov txiaj ntsig zoo dua.

Hmoov metallurgy cov ntaub ntawv thiab cov khoom lag luam hauv kev txhim kho yav tom ntej

1, tus neeg sawv cev ntawm cov hlau-raws li alloy, yuav yog cov ntim loj ntawm cov khoom lag luam precision, kev txhim kho cov qauv zoo.

2. Ua haujlwm siab alloy nrog cov qauv microstructure, ua haujlwm nyuaj thiab ua tiav qhov ntom.

3. Cov alloys tshwj xeeb, feem ntau muaj cov theem sib xyaw, yog tsim los ntawm cov txheej txheem densification.

4, manufacturing heterogeneous cov ntaub ntawv, amorphous, microcrystalline los yog metastable alloy.

5, kev ua haujlwm tshwj xeeb thiab tsis yog daim ntawv lossis cov khoom sib xyaw ua ke.

Ua ntej, qhov zoo ntawm cov hmoov metallurgy txheej txheem

1, tuaj yeem ua cov ntaub ntawv tshwj xeeb. Cov khoom siv hmoov metallurgy txoj kev tuaj yeem tsim cov hlau refractory nrog rau cov khoom sib txuas, pseudo alloys, thiab cov khoom ntxeem tau.

2, txuag hlau, txo cov nqi.Vim cov hmoov metallurgy tuaj yeem nias rau hauv qhov loj kawg ntawm kev sib cog lus, tsis tas yuav siv cov tshuab ua haujlwm.Qhov kev poob ntawm cov hlau ua li no tsuas yog 1 mus rau 5 feem pua, piv nrog rau 80 feem pua. ib txwm ua.

Txoj kev loj hlob ntawm hmoov metallurgy khoom

1, qhov zoo ntawm cov khoom siv: hmoov metallurgy yog cov neeg sawv cev ntawm cov hlau-raws li alloy, yuav raug tsim los rau cov ntim loj ntawm cov khoom lag luam, cov khoom siv zoo.

2, kev ua haujlwm siab alloy: hmoov metallurgy manufacturing muaj cov qauv microstructure, kev ua haujlwm yog qhov nyuaj thiab ntom ntom ntom ntom ntom ntom.

3, sib xyaw theem tshwj xeeb alloy: hmoov metallurgy nrog txhim kho cov txheej txheem los tsim cov hlau tshwj xeeb uas muaj cov theem sib xyaw.

4, cov khoom sib xyaw: ua cov khoom tshwj xeeb thiab tsis yog daim ntawv lossis cov khoom sib xyaw ua ke.

5. Kev npaj cov khoom siv purity siab.Powder metallurgy txheej txheem hauv cov txheej txheem tsim cov khoom tsis yaj cov khoom, nws yuav tsis tov nrog lwm yam khoom coj los ntawm impurities, thiab sintering yog nqa tawm hauv lub tshuab nqus tsev thiab txo qhov cua, tsis ntshai ntawm oxidation thiab yuav tsis muaj kuab paug ntawm cov khoom siv.Yog li ntawd, lub purity ntawm cov khoom yog kuj siab.

6, Kev ua kom raug ntawm cov khoom faib khoom.Powder metallurgy txoj kev tuaj yeem ua kom qhov tseeb thiab qhov sib xws ntawm cov khoom muaj pes tsawg leeg hauv kev faib ua feem.

7, loj ntau lawm kom txo tau cov nqi.Powder metallurgy yog tsim rau zus tau tej cov khoom uas muaj ib tug loj tus naj npawb ntawm cov qauv, xws li iav thiab lwm yam khoom uas muaj nqi siab, uas yuav txo tau cov nqi ntau lawm.
