Cov khib nyiab kho cua sov ntawmloj forgingssiv nws tus kheej cua sov kom ncaj qha tshav kubforgingsTom qab forging, uas yog, kev kho cua sov khib nyiab ntawm forgings tshem tawm cov txheej txheem ntawm reheating forgings ua ntej tom qab forging tshav kub kev kho mob, thiab cov khib nyiab kho cua sov feem ntau muaj cov hauv qab no.

1, qabforging, pov tseg tshav kub homogenization kev kho cua sov.Covforgingsraug xa ncaj qha mus rau qhov cub kho cua sov tom qab tsim, tseem raws li cov txheej txheem kev kho cua sov, qhov kub ntawm qhov sib txawv ntawm forgings tom qab homogenization, tuaj yeem txo lub sijhawm tuav, txoj kev no yog hu ua khib nyiab kub homogenization tshav kub kho.Rau cov duab ntawm complex, yog ib tug loj cross-section hloov forgings siv cov txheej txheem yuav forged zoo stability.
2, Kev kho cua sov ncaj qha tom qabforging.Tom qabforgingyog tsim, cov khib nyiab kub ntawm forging yog siv rau kev kho cua sov ncaj qha, thiab cov forging thiab kev kho cua sov yog zoo sib xws ua ke, uas txuag tau ntau lub zog pov tseg los ntawm reheating ntawm kev kho cua sov.
3 ,pogforging, siv ib feem ntawm cov khib nyiab pov tseg rau kev kho cua sov.Cov forgings tau txias txog li 600 ~ 650 ℃ tom qab tsim, thiab tom qab ntawd cov forgings tau rov ua dua rau qhov kub thiab txias rau kev kho cua sov.Txoj kev no tuaj yeem ua kom zoo rau cov qoob loo loj, thiab txuag lub zog noj ntawm cov cua sov forgings los ntawm chav tsev kub txog 600 ~ 650 ℃, feem ntau haum rau forgings nrog cov qoob loo loj.Ib tug loj tus naj npawb ntawm daim ntawv thov piv txwv qhia tau hais tias cov microstructure thiab cov khoom ntawm forgings tom qab pov tseg tshav kub kev kho mob mus txog theem ntawm kev kho cua sov thiab muaj cov txheej txheem zoo stability thiab reproducibility los ntawm kev tswj cov cua txias tsis tom qab.tsim.Kev siv hluav taws xob pov tseg rau kev kho cua sov tshem tawm cov txheej txheem cua sov, txuag lub zog, thiab cov nqi peev thiab kev saib xyuas cov khoom siv kho cua sov.Kev lag luam forging yog cov neeg siv khoom siv hluav taws xob loj, thiab kev kho cua sov ntawm forgings yog cov neeg siv khoom siv hluav taws xob loj hauv forging ntau lawm, suav txog li 30% ~ 35% ntawm tag nrho cov kev siv hluav taws xob ntawm tag nrho cov forging ntau lawm.Forgingskev siv hluav taws xob suav txog li 8% ~ 10% ntawm tus nqi forgings, kev siv hluav taws xob tsis tuaj yeemforgingscov nqi tsim khoom, cov txiaj ntsig kev lag luam ntawm kev lag luam, thiab qhov teeb meem ntawm lub zog muaj feem cuam tshuam nrog kev txhim kho kom ruaj khov ntawm qhov teeb meem, muaj feem cuam tshuam rau kev ciaj sia ntawm qhov teeb meem loj.Yog li ntawd, kev siv forging khib nyiab rau kev kho cua sov, txuag hluav taws xob, efficiency thiab lwm yam yog pom tseeb, tsis tsuas yog txuag lub zog, txo cov txheej txheem, tab sis kuj tiv thaiv ib puag ncig.
