Hmoov metallurgyyog ib qho kev tshawb fawb thiab thev naus laus zis uas kawm thiab tsim cov hmoov hlau ntau thiab siv cov hmoov ua raw khoom los npaj cov khoom siv hlau thiab cov khoom los ntawm kev nias, sintering thiab tsim nyog ua tom qab. Nws yog cov txheej txheem ntau lawm nrog me me los yog tsis muaj kev txiav, uas tuaj yeem ua rau cov khoom siv nrog cov duab nyuaj thiab cov qauv tsim muaj zog thaum txo cov nqi. Nws yog txoj hauv kev tseem ceeb rau kev tsim khoom loj ntawm kev coj tus kheej-lubricating qhov chaw ntawm tus nqi qis.
Qhov zoo ntawm cov txheej txheem hmoov metallurgy
Qhov zoo: 1. Feem ntau cov hlau refractory thiab lawv cov tebchaw, oxide dispersion muaj zog alloys, cov ntaub ntawv ntxeem tau, cov ntaub ntawv ceramic thiab cemented carbides tsuas yog tsim los ntawm cov hmoov metallurgy txoj kev.
2. Txij li cov hmoov metallurgy txoj kev tuaj yeem raug nias rau hauv qhov loj kawg ntawm qhov khoob tsis muaj lossis me me rau kev ua haujlwm tom ntej, nws tuaj yeem txuag tau cov hlau ntau thiab txo tus nqi ntawm cov khoom. Thaum tsim khoom los ntawm cov hmoov metallurgy, qhov poob ntawm cov hlau tsuas yog 1-5%. Thaum tsim los ntawm cov txheej txheem casting zoo tib yam, qhov poob ntawm cov hlau tuaj yeem ncav cuag 80%.
3. Txij li cov hmoov metallurgy txheej txheem tsis yaj cov khoom hauv cov txheej txheem tsim khoom, nws tsis ntshai ntawm kev sib xyaw impurities, thiab sintering yog nqa tawm hauv lub tshuab nqus tsev thiab txo cov cua, tsis ntshai ntawm oxidation, thiab yuav tsis ua rau muaj kuab paug rau cov khoom, yog li nws muaj peev xwm kom tau txais purity siab. s khoom.
4. hmoov metallurgy tuaj yeem ua kom qhov tseeb thiab qhov sib xws ntawm cov khoom siv sib xyaw.
5. Hmoov metallurgy yog tsim los tsim cov khoom zoo tib yam thiab cov khoom siv ntau, tshwj xeeb tshaj yog cov iav thiab lwm yam khoom uas muaj nqi siab. Kev tsim khoom los ntawm cov hmoov hlau metallurgy tuaj yeem txo cov nqi ntau lawm.
Qhov tsis zoo ntawmhmoov metallurgy txheej txheem
1. Xav txog qhov loj ntawm ib feem thaum tsis muaj batch loj
2. Tus nqi pwm yog siab dua cov pwm pwm
Txoj kev loj hlob ntawmhmoov metallurgy cov ntaub ntawv thiab cov khoom
1. Cov neeg sawv cev hlau-raws li alloys yuav raug tsim los rau hauv cov khoom loj-ntim precision thiab cov khoom siv zoo.
2. Kev tsim cov hlau ua haujlwm siab nrog cov qauv microstructure, nyuaj rau kev ua haujlwm thiab ntom ntom.
3. Siv cov txheej txheem densification zoo dua los tsim cov alloys tshwj xeeb ntawm cov roj sib xyaw ua ke.
4. Kev tsim cov khoom siv heterogeneous, amorphous, microcrystalline lossis metastable alloys.
5. Machining ntawm cov ntaub ntawv tshwj xeeb thiab txawv txawv lossis cov khoom sib xyaw ntawm cov khoom siv hlau.
Casting yog txheej txheem uas cov hlau yog smelted rau hauv cov kua uas ua tau raws li tej yam yuav tsum tau thiab poured rau hauv pwm. Tom qab txias, solidification, thiab tu, ib tug casting nrog ib tug predetermined zoo, loj thiab kev ua tau zoo yog tau.
Casting nta:
1. Casting muaj qhov dav ntawm cov khoom siv raw thiab cov nqi tsim khoom tsawg. Piv nrog rau lwm cov txheej txheem tsim, casting muaj qhov pom tseeb zoo.
2. Casting yog kua hlau sib sau, yog li nws tuaj yeem tsim qhov khoob lossis qhov chaw nrog cov duab nyuaj, tshwj xeeb tshaj yog ntau qhov ntau thiab tsawg thiab cov lus qhia tshwj xeeb nrog cov kab noj hniav nyuaj.
3. Qhov loj, qhov hnyav thiab ntau lawm batch ntawm castings tsis txwv, uas yog hloov tau ntau dua
4. Tsawg tus nqi tsim khoom thiab kev txuag nyiaj. Kev siv tus nqi ntawm cov ntaub ntawv yog siab thiab daim ntawv thov yog dav heev
5. Cov cuab yeej cuab tam ntawm castings yog phem tshaj forgings
6. Vim muaj cov txheej txheem ntau lawm ntawm casting, ntau cov ntaub ntawv, thiab kev tswj tsis zoo, qhov zoo ntawm cov castings tsis ruaj khov, thiab cov khoom siv scrapped kuj zoo heev.
7. Kev ua haujlwm tsis zoo
Casting qhov zoo:
1. Ua cov duab puab, tshwj xeeb tshaj yog 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
2. Castings muaj dav adaptability thiab yooj. Feem ntau siv cov khoom siv hlau hauv kev lag luam tuaj yeem siv rau casting. Qhov hnyav ntawm castings tuaj yeem nyob ntawm ob peb grams mus rau ntau pua tons, thiab phab ntsa thickness yog li 0.5 hli mus rau 1m.
3. Cov khoom siv raw ntawm castings yog pheej yig thiab tus nqi qis
tsis txaus:
1. Cov qauv ntawm cov khoom yog xoob, cov nplej yog ntxhib, thiab qhov tsis xws luag xws li shrinkage kab noj hniav, shrinkage porosity, thiab pores yog yooj yim generated hauv. Yog li ntawd, cov cuab yeej cuab tam ntawm cov castings, tshwj xeeb tshaj yog cuam tshuam toughness, yog qis dua cov forgings ntawm tib cov khoom.
2. Lub casting zoo tsis ruaj khov txaus.
