Forgingsbelongs rau lub tsev ntaub ntawv kev lag luam, nws siv yog dav, los ntawm lub tswvyim ntawm:forgingsyog cov hlau yog thov siab, los ntawm cov yas deformation los tsim cov duab uas yuav tsum tau los yog qhov tsim nyog compression quab yuam ntawm cov khoom.
Forgingyog siv cov cuab yeej forging rau forging forming ntawm bar Tshuag, feem ntau tsis tuaj yeemforgingntau yam khoom cuav, xav tau kev ua haujlwm loj, tab sis forging qauv yog compact, tsis yooj yim rau sab hauv tsis xws luag, yog li nws yog dav siv nyob rau hauv xav tau qhov chaw ua, xws li rooj zaum, valve core, valve qia, nyob rau hauv lub siab thiab muaj zog corrosion alloy valve. , forging lub cev kuj yog dav siv.
Piv nrog rau cov castings, lub cev ntawm forged li qub muaj cov qauv zoo dua qub, qhov ntom ntom zoo dua, muaj zog zoo dua qub, cov yam ntxwv zoo dua qub, thiab qhov yuam kev tsawg dua. Kev taw qhia kev tsim kho (pipeline) muaj kev ua tau zoo dua li cov castings ntawm tag nrho lub zog thiab kev ntxhov siab.
Siab zog - Kubforgingtxhawb nqa crystallization thiab grain refinement, tso cai rau cov khoom kom ua tiav lub zog siab tshaj plaws thiab sib xws nrog qhov sib txawv me me ntawm ib feem mus rau ib feem. Particles ntws precisely raws lub cev profile. Cov kev txuas txuas ntxiv no pab txo qis qhov tshwm sim ntawm kev qaug zog lossis kev ua txhaum ntau.

Structureal integrity - Forging tshem tawm cov teeb meem sab hauv thiab ua kom muaj kev sib koom ua ke thiab zoo ib yam metallographic qauv, ua kom muaj kev ua tau zoo.Forgingsmuab lub neej ua haujlwm ntev thiab kev pabcuam tsis muaj teebmeem qhov twg muaj kev ntxhov siab thiab nyob rau hauv-crystal corrosion yog ib qho teeb meem loj.
Kev ntseeg tau - Cov qauv kev ncaj ncees Forging tshem tawm cov teeb meem sab hauv thiab ua kom muaj kev sib raug zoo thiab cov qauv metallographic zoo ib yam, ua kom muaj kev ua tau zoo. Forgings muab kev pab cuam lub neej ntev thiab kev pabcuam tsis muaj teebmeem qhov twg muaj kev ntxhov siab thiab nyob rau hauv-crystal corrosion yog ib qho teeb meem loj.
Kev ruaj ntseg zoo - Los ntawm kev siv forgings, nrog rau lawv qhov sib xws thiab zoo, qhov xav tau X-rays rau chav kawm 1 cam khwb cia qhov chaw raug tshem tawm. US Navy tuav tib tus cwj pwm thaum siv forgings raws li cov khoom ntawm nuclear submarines thiab cov dav hlau thauj. Tag nrho cov kev cai ASME Code rau forgings yog kuaj ultrasonic (UT), sib nqus particle soj ntsuam (MT) los yog kua nkag mus kuaj (PT). Cov khib nyiab forgings pom los ntawm UT, MT, lossis PT txoj kev yog tsawg heev. Cheebtsam tau yuav nrog lub sijhawm xa khoom, yog li kev xa khoom ntawm lub valve yog ntau txhim khu kev qha.
Directional configuration ntawm lub cev valve - creep qaug zog lub zog yog ntau tshaj 3 lub sij hawm siab tshaj ntawm cov casting nyob rau hauv cov kev mob ntawm loj kub hloov.
Lub tuam txhab lub ntsiabflange, forging, forging ua, muaj lus nug lossis xav tau txais tos nug thiab sib tham.
