Qhov zoo ntawm cov hmoov metallurgy txheej txheem

1, feem coob ntawm cov tshuaj refractory hlau thiab lawv cov khoom sib txuas, cov khoom tsis muaj tseeb, cov khoom ntxeem tau tuaj yeem tsuas yog tsim cov hmoov hlau metallurgy txoj kev.

2, vim hais tias cov hmoov hlau metallurgy txoj kev tuaj yeem raug nias rau qhov kawg loj ntawm kev cog lus, tsis tas lossis xav tau kev hloov kho tom qab siv tshuab, nws tuaj yeem txuag cov hlau ntau, txo cov nqi khoom.Qhov poob ntawm cov hlau hauv kev tsim cov khoom los ntawm cov hmoov hlau ua kom zoo. txoj kev yog tsuas yog 1-5%, thaum lub sij hawm poob ntawm cov hlau hauv kev tsim cov khoom lag luam los ntawm cov txheej txheem casting zoo tib yam yuav dhau 80%.

3, vim hais tias cov hmoov txheej txheem hauv cov khoom tsim cov txheej txheem tsis yaj ntawm cov khoom, nws tsis ntshai ua kom sib xyaw nrog cov impurities coj los ntawm tus ntsia thiab deoxidizer, thiab sintering yog feem ntau nqa tawm hauv lub tshuab nqus tsev thiab txo qhov huab cua, tsis txhob ntshai ntawm oxidation , thiab yuav tsis muab cov pa phem rau cov khoom siv, nws yog ua tau los ua cov ntaub ntawv purity siab.

4, hmoov metallurgy txoj kev tuaj yeem ua kom paub tseeb thiab zoo ntawm cov khoom sib xyaw ua ke piv.5, hmoov metallurgy yog qhov tsim nyog rau kev tsim cov khoom zoo ib yam thiab cov khoom lag luam loj, tshwj xeeb tshaj yog iav thiab lwm yam txheej txheem ua nqi ntawm cov khoom, nrog hmoov metallurgy kev tsim khoom lag luam tuaj yeem txo cov nqi tsim khoom.

Cov txheej txheem yooj yim ntawm hmoov metallurgy txheej txheem yog

1, kev npaj ntawm cov hmoov nyoos hmoov.Txhua txheej txheem pulverizing tuaj yeem raug faib ua ob pawg: kev kho tshuab thiab lub cev-tshuaj lom neeg.Qhov kev siv tshuab tuaj yeem muab faib ua: cov tshuab tsoo thiab atomization txoj kev; Lub cev thiab tshuaj ntxiv tau muab faib ntxiv rau hauv electrochemical corrosion. txoj kev, txo txoj kev, tshuaj siv txoj kev, txo-tshuaj lom neeg 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. Hmoov ua rau cov duab yam xav tau ntawm cov dawb thaiv.Qhov hom phiaj molding yog ua kom muaj qee yam duab thiab qhov loj ntawm qhov ua kom nruj me me, thiab ua kom nws muaj qee qhov ceev thiab lub zog.Qhov kev qhia moulding yog qhov yooj yim muab faib rau hauv siab molding thiab tsis - siab molding.Pressure molding yog qhov feem ntau siv moulding.

3. Kev ua txhaum ntawm billet.Sintering yog ib qho txheej txheem tseem ceeb hauv hmoov metallurgy.Qhov kawg lub cev thiab cov khoom siv tau los ntawm sintering lub kaw lus tsis txaus ntseeg tom qab sib sau.Sintering tau muab faib ua chav sintering thiab multi - tivthaiv sintering.The sintering kub yog qis dua qhov melting taw tes ntawm cov hlau thiab alloy siv rau cov theem tsis ua hauj lwm sintering ntawm chav ua haujlwm system thiab multi-tivthaiv system.Rau cov ua kua theem sintering ntawm cov kab ke sib txuam, qhov kub siab sintering feem ntau qis dua melting point ntawm refractory tivthaiv, tab sis siab dua lub ntsiab lus melting ntawm fusible tivthaiv. Txuas ntxiv rau qhov sintering zoo tib yam, muaj xoob sintering, yaj txoj kev tso tawm, txoj kev kub nias thiab lwm cov txheej txheem tshwj xeeb sintering.

4. Cov kev ua tiav tom qab ua tiav ntawm cov khoom.Qhov kev kho tom qab ua txhaum kev tuaj yeem tau txais coj los ntawm ntau txoj hauv kev raws li cov khoom sib txawv ntawm cov khoom.Yog li kev ua tiav, kev nqus, tshuab, kho kub thiab electroplating. Tsis tas li ntawd, nyob rau xyoo tsis ntev los no, qee cov txheej txheem tshiab xws li dov thiab forging kuj tau siv rau kev ua cov hmoov hlau cov khoom tom qab ua txhaum, thiab ua tiav cov txiaj ntsig zoo dua.

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

1, tus neeg sawv cev ntawm cov hlau-qhov sib xyaw, yuav muaj ntau qhov loj ntawm cov khoom ua tau zoo, kev ua haujlwm zoo qauv kev txhim kho.

2. Chaw ua khoom siv qib siab ua haujlwm nrog cov microstructure tsis zoo, ua haujlwm nyuaj thiab ua kom tiav qhov ntom ntom.

3. Cov alloys tshwj xeeb, feem ntau muaj cov qib sib xyaw, yog tsim los ntawm cov txheej txheem txhim kho kom muaj txheej txheem.

4, tsim cov khoom siv heterogeneous, amorphous, microcrystalline lossis metastable alloy.

5, kev ua cov cim tshwj xeeb thiab tsis yog cov qauv dav dav lossis cov khoom sib xyaw ua ke ntawm cov khoom sib txawv.

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.
