Cov hmoov hlau yog dab tsi?

Ib qho kev sib sau ntawm cov hlau uas tsawg dua ib millimeter yog hu ua hlau hmoov. Qhov no yog cov khoom siv raw khoom siv hauv cov hmoov hlau metallurgy thiab suav nrog ib leeg hlau, alloy, thiab qee yam refractory composite hmoov uas muaj cov yam ntxwv hlau.

Cov hmoov hlau yog dab tsi?

Hmoov hlau txheej txheej txheem yog ua hlau los yog siv hlau hmoov (los yog hlau hmoov thiab tsis yog hlau hmoov sib tov) raws li raw cov ntaub ntawv, tom qab tsim thiab MIM sintering, tsim hlau cov ntaub ntawv, composite cov ntaub ntawv thiab ntau yam khoom siv technology. Generalized hmoov hlau qhov kev lag luam suav nrog cov cuab yeej hlau thiab pob zeb, cemented carbide, cov khoom sib nqus. Hauv kev nkag siab nqaim, Cov hmoov hlau qhov chaw lag luam tsuas yog hais txog cov khoom siv hmoov metallurgy, suav nroghmoov metallurgy qhov chaw(sau npe rau feem coob), roj-cov kabmob thiabhlau txhaj molding khoom.

Hmoov hlau Cheebtsam

Hmoov hlau yam ntxwv

• qhov ntom ntawm cov khoom yog tswj tau, xws li cov khoom ntxeem tau, cov khoom siv ntom ntom zoo;
• hmoov nplej zoo, zoo li microstructure, tsis muaj kev sib cais;
• nyob ze ntawm kev tsim, raw khoom siv tus nqi> 95%;
• tsawg dua tsis txiav, txiav ua tsuas yog 40 ~ 50%;
• cov khoom sib xyaw yog tswj tau, uas yog qhov tsim nyog rau kev npaj cov khoom sib xyaw;
• kev npaj ntawm cov hlau refractory, cov ntaub ntawv ceramic thiab cov ntaub ntawv nuclear.

Hmoov hlau qhov chaw pib txheej txheem ntws

1, Pulverizing

Pulverizing yog txheej txheem ntawm kev ua raw cov ntaub ntawv rau hauv hmoov. Txoj kev siv pulverizing feem ntau yog oxide txo txoj kev thiab txhua yam txheej txheem.

2. Sib tov

Kev sib xyaw yog txheej txheem ntawm kev ua cov hmoov nplej los ntawm kev sib tov txhua yam ntawm cov hmoov uas yuav tsum tau ua hauv ib qho kev faib ua feem thiab homogenizing nws. Muab faib rau hauv qhuav, ib nrab qhuav thiab ntub peb, raws li qhov yuav tsum tau sib txawv.

3, tsim

Kev sib sau yog cov txheej txheem ntawm kev ua kom tsis muaj dab tsi nrog cov duab, qhov loj me thiab qhov ntom ntom los ntawm kev thauj cov khoom sib xyaw ua ke rau hauv cov xovxwm tuag nyob rau hauv lub siab hnyav. Moulding txoj kev yog muab faib ua siab molding thiab tsis muaj siab molding. Lub siab molding yog feem ntau siv hauv molding.

4, Sintering

5. Tom qab ua tiav

 Tom qab sintering kev kho mob, raws li sib txawv hmoov hlau qhov yuav tsum tau, coj ntau txoj kev. Xws li xov, dipping, machining, kho cua sov thiab electroplating. Tsis tas li ntawd, nyob rau xyoo tas los no, qee cov txheej txheem tshiab xws li dov thiab forging kuj tau siv rau sintering ntawm hmoov metallurgy cov ntaub ntawv thiab ua tiav cov txiaj ntsig zoo dua.

Hmoov sinteringyog txheej txheem tseem ceeb hauv cov txheej txheem hmoov metallurgy. Tom qab tsim, lub billet yog sintered kom tau qhov kawg xav tau lub cev thiab txhua yam khoom. Sintering hauv metallurgy muab faib ua chav tsev sintering thiab multi-system sintering. Ntxiv nrog rau qhov zoo tib yam sintering, muaj xoob sintering, immersion, kub nias thiab lwm yam txheej txheem sintering tshwj xeeb.
