Forged li qub yog forged thiab feem ntau yog siv nyob rau hauv high-qib pipelines. Txoj kab uas hla yog me me, feem ntau hauv qab DN50. Tab sis kuj tseem muaj qee qhov txawv teb valve nrog loj forged diameters, xws li American VTON forged nres valve, nrog diameters xws li DN 15-500. Cov ntaub ntawv ntawm forged nres li qub feem ntau muab faib ua A105, forged stainless hlau, P91, F91, thiab lwm yam.

- Forged li qub yog forged thiab feem ntau yog siv nyob rau hauv high-qib pipelines. Txoj kab uas hla yog me me, feem ntau hauv qab DN50.
1. Forging: Nws yog ib txoj hauv kev uas siv cov tshuab forging los ua kom lub zog ntawm cov hlau blanks ua rau cov yas deformation kom tau txais forgings nrog qee yam khoom siv, qee yam duab thiab ntau thiab tsawg.
2. Ib qho ntawm ob qhov tseem ceeb ntawm forging. Los ntawm forging, cov hlau li-cam khwb cia hlau looseness thiab vuam qhov tuaj yeem raug tshem tawm. Cov cuab yeej cuab tam ntawm forgings feem ntau zoo dua li cov khoom siv tib yam. Rau cov khoom tseem ceeb hauv cov tshuab nrog cov khoom hnyav thiab kev ua haujlwm hnyav, forgings feem ntau yog siv, tshwj tsis yog rau cov duab yooj yim uas tuaj yeem dov daim hlau, profiles lossis welded qhov chaw.
3. Forging tuaj yeem muab faib ua: ① Qhib forging (free forging) raws li txoj kev tsim. Kev cuam tshuam quab yuam los yog siab yog siv los deform cov hlau ntawm lub sab sauv thiab qis resistors (anvils) kom tau txais qhov yuav tsum tau forgings. Feem ntau muaj ob hom kev tuav forging thiab mechanical forging. ② Kaw hom forging. Cov hlau dawb paug yog compressed thiab deformed nyob rau hauv lub forging tuag chamber nrog ib tug tej yam zoo li kom tau forgings, uas yuav muab faib ua tuag forging, txias taub hau, teb forging, extrusion, thiab lwm yam. forging (qhov kub ntawm cov txheej txheem yog siab tshaj qhov kub ntawm recrystallization ntawm cov hlau dawb paug), sov forging (qis dua qhov recrystallization kub) thiab txias forging (qhov kub li qub).
4. Cov ntaub ntawv forging feem ntau yog carbon steel thiab alloy steel ntawm ntau yam khoom, ua raws li txhuas, magnesium, titanium, tooj liab, thiab lwm yam thiab lawv cov alloys. Lub xeev cov ntaub ntawv tseem ceeb muaj xws li bar Tshuag, ingot, hlau hmoov thiab kua hlau, thiab lwm yam. Qhov piv ntawm qhov chaw hla ntawm cov hlau ua ntej deformation mus rau qhov chaw seem tuag tom qab deformation yog hu ua forging ratio. Qhov kev xaiv raug ntawm forging piv muaj ntau yam ua nrog kev txhim kho cov khoom zoo thiab txo cov nqi.
