Cov txheej txheem hmoov hmoov metallurgy yog qhia rau hauv plaub theem

Cov txheej txheem txheej txheem ntawm hmoov metallurgy yog hmoov npaj (sib xyaw thiab sib xyaw) - nias tshuaj molding - sintering - kev kho mob tom qab.

Tus txheej txheem no tau piav qhia txhua yam hauv qab no.

1, kev npaj cov hmoov cuam tshuam txog kev npaj cov khoom: raws li cov khoom xav tau, raws li kev tsim cov khoom xyaw, thiab tom qab ntawd muab cov sib xyaw ua ke.Qhov txheej txheem no feem ntau xav txog qhov loj me, kev ua kom haum thiab ntau qhov ceev ntawm hmoov.Qhov qhov loj me ntawm cov hmoov txiav txim siab qhov sib txawv nruab nrab ntawm cov khoom siv puv thiab tseem cuam tshuam rau cov bridging effect.Nws zoo dua yog siv cov khoom sib xyaw tam sim ntawd thiab tsis cia lawv ntev dhau los.Prolonged kev tso kawm tuaj yeem ua rau ya raws thiab oxidation.

2, tus txheej txheem hluav taws xob xav kom nkag siab txog txoj kev tsuj tawm: ib-txoj kev tsuj thiab ob-txoj kev tsuj.Qhov rau nyias nias txoj kev, kev faib tawm sab hauv cov khoom kuj tseem sib txawv.Qhov muab tso, rau unidirectional nias, raws li qhov deb ntawm cov punch nce, kev sib txhuam rau ntawm phab ntsa sab hauv ntawm kev tuag txo lub siab, thiab qhov ntom ntom nti sib txawv nrog lub siab.

3. Cov roj ua kua feem ntau ntxiv rau cov hmoov txhawm rau txhawm rau ua kom yooj yim nias thiab pob zeb.Lubricants txo qhov kev sib txhuam ntawm cov hmoov ntawm cov qib siab thiab nce qhov ceev nrawm hauv cov txheej txheem ntawm nias.Txawm li cas los xij, thaum lub siab hloov theem, raws li cov roj nplua nyeem tau sau rau hauv qhov sib txawv nruab nrab ntawm cov hmoov sib xyaw, nws tuaj yeem, ntawm qhov tsis sib thooj, hinder qhov ntom ntawm cov khoom.Qhov kev tswj hwm qhov tso tawm ntawm cov khoom zam kom tsis txhob muaj qhov tshwm sim saum npoo los ntawm cov txheej txheem demoulding.

4. Hauv kev nias, nws yog ib qho tsim nyog kom paub tseeb qhov nyhav ntawm qhov khoom, uas yog qhov tseem ceeb heev, vim tias lub siab tsis txaus ntseeg hauv ntau lub hoobkas yuav ua rau muaj qhov nyhav nyhav sib txawv, uas cuam tshuam ncaj qha rau kev ua tiav ntawm qhov khoom kawg.Qhov nias cov khoom lag luam yuav tsum tau muab cov hmoov av uas tsis huv thiab tsis zoo tso rau saum npoo ntawm cov khoom thiab muab tso kom zoo rau hauv cov cuab yeej kom tiv thaiv impurities.
