Compaction yog txheej txheem tsim khoom tseem ceeb hauv kev tsim cov hmoov metallurgy qhov chaw.

Cov txheej txheem nias ntawm hmoov metallurgy muab faib ua plaub kauj ruam.Ua ntej, kev npaj cov hmoov nrog rau kev npaj cov ntaub ntawv.Raws li cov khoom xav tau, cov khoom xyaw yog npaj raws li cov qauv, thiab tom qab ntawd cov khoom sib tov yog tov.Txoj kev no feem ntau txiav txim siab qhov loj me, fluidity thiab bulk ntom ntawm cov hmoov.Lub particle loj ntawm cov hmoov txiav txim qhov sib txawv ntawm cov filling hais.Siv cov khoom sib xyaw tam sim ntawd, thiab tsis txhob cia lawv ntev dhau.Lub sijhawm ntev yuav ua rau cov dej noo thiab oxidation.

Qhov thib ob yog nias lub hmoov.Feem ntau yog ob txoj kev nias uas feem ntau siv rau hauv cov txheej txheem ntawm cov hmoov hlau metallurgy, uas yog ib txoj kev nias thiab ob txoj kev nias.Vim muaj ntau txoj kev nias, qhov sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv.Nyob rau hauv cov ntsiab lus yooj yim, rau unidirectional nias, nrog rau qhov nce ntawm qhov kev ncua deb ntawm lub punch, qhov kev sib txhuam quab yuam ntawm lub puab phab ntsa ntawm cov tuag txo lub siab, thiab qhov ceev hloov nrog kev hloov ntawm lub siab.

Lubricants feem ntau yog ntxiv rau cov hmoov los pab nias thiab demoulding.Thaum lub sij hawm nias cov txheej txheem, cov roj nplua nyeem txo cov kev sib txhuam ntawm cov hmoov ntawm cov theem qis thiab ua kom ceev ceev;Txawm li cas los xij, nyob rau theem siab, raws li cov roj nplua nyeem sau qhov sib txawv ntawm cov hmoov hmoov, ntawm qhov tsis sib xws, nws yuav cuam tshuam qhov ntom ntawm cov khoom.Kev tswj lub zog tso tawm ntawm cov khoom kom tsis txhob muaj qhov tsis xws luag los ntawm cov txheej txheem demoulding.

Nyob rau hauv cov hmoov metallurgy nias txheej txheem, nws yog ib qho tsim nyog kom paub meej tias cov khoom hnyav, uas yog ib qho tseem ceeb heev, vim hais tias lub siab tsis ruaj khov nyob rau hauv ntau lub hoobkas yuav ua rau qhov hnyav hnyav sib txawv, uas cuam tshuam ncaj qha rau cov khoom lag luam.Cov khoom nias yuav tsum tau tshuab tawm cov hmoov seem thiab cov impurities ntawm cov khoom nto, muab tso rau hauv cov khoom zoo thiab tiv thaiv los ntawm impurities.
