Stainless hlau forgings

Los ntawm forging, tsis xws luag xws li-cam khwb cia looseness tsim nyob rau hauv cov txheej txheem smelting yuav raug tshem tawm, thiab cov microstructure yuav optimized. Cov cuab yeej cuab tam ntawm forgings feem ntau zoo dua li cov castings ntawm tib cov khoom.

Rau cov khoom tseem ceeb hauv cov tshuab uas muaj kev thauj khoom hnyav thiab kev ua haujlwm hnyav, forgings feem ntau yog siv ntxiv rau dov daim hlau, profiles lossis welded qhov chaw nrog cov duab yooj yim.

Qinhuangdao Zhongwei Precision Machinery Co., Ltd. Cov khoom tuaj yeem tsim raws li cov duab kos thiab cov tshuaj sib xyaw ua ke, thiab kev sib koom ua ke ntawm kev sib tsoo dawb, tuag forging, ntxhib machining, kev kho cua sov thiab kev ua tiav tiav. Kev koom tes ntev nrog crane, roj av, tshuaj, mining, metallurgy, hydraulic, coking, tsheb ciav hlau, siv tshuab thiab lwm yam lag luam.

Yam khoom

1. Raws li txoj kev txav ntawm lub billet, forging yuav muab faib ua dawb forging, kaw tuag forging thiab kaw upsetting.

Dawb forging. Siv cov kev quab yuam los yog siab kom deform cov hlau nruab nrab ntawm cov hlau sab sauv thiab qis kom tau txais cov forgings uas yuav tsum tau muaj, muaj ob hom kev tuav forging thiab mechanical forging. Tuag forging tau muab faib ua qhov qhib tuag forging thiab kaw tuag forging, thiab tuaj yeem muab faib ua lub taub hau txias, yob forging, radial forging thiab extrusion, thiab lwm yam.

Raws li qhov kub deformation, forging tuaj yeem muab faib ua kub forging. Ntawm 300 thiab 800 degree, nws yog hu ua sov forging lossis semi-kub forging.

Khoom nta

Forging method Tom qab kub ua hauj lwm deformation, vim lub deformation thiab recrystallization ntawm stainless hlau, coarse dendrites thiab columnar nplej ua equiaxed recrystallized lug nrog finer nplej thiab uniform loj, thiaj li hais tias tus thawj segregation, looseness, slag inclusion, thiab lwm yam. txhim kho mechanical zog.

Nws tuaj yeem ua kom cov khoom siv kho tshuab thiab lub neej ua haujlwm ntev ntawm cov khoom. Tuag forging yog siv, uas yog unmatched los ntawm castings.

① Martensitic (20Crl3, 40Crl3, 14Crl7N12, thiab lwm yam) stainless hlau undergoes allotropic transformation nyob rau hauv cov txheej txheem ntawm cua sov thiab txias. Rau hom hlau no, tsis muaj qhov tshwj xeeb xav tau rau qhov kawg-hluav taws deformation.

② Cov tsim ntawm 8-ferrite yuav tsum tau zam thaum lub sij hawm forging thiab cua sov ntawm martensitic stainless hlau, vim hais tias cov tsos ntawm ferrite yuav ua rau tawg nyob rau hauv lub forgings, thiab nws yog tsim nyog kom tsis txhob overheating los ntawm overheating ntawm cov hlau. Nto decarburization ntawm forgings tuaj yeem ua rau ntau tshaj ferrite tsim, yog li decarburization decarburization yuav tsum tsawg.

③ Martensitic stainless hlau yog nquag tawg tom qab forging. Qhov no yog vim hais tias cov qauv martensite thiab carbide yuav tshwm sim thaum huab cua txias tom qab forging, thiab qhov tshwm sim sab hauv kev ntxhov siab yog loj, yog li nws yuav tsum tau txias maj mam tom qab forging, feem ntau ntawm 200 degree xuab zeb maj mam txias hauv lub qhov los yog slag, thiab annealing yuav tsum tau. nqa tawm hauv lub sijhawm tom qab raug tshem tawm ntawm lub qhov xuab zeb kom tsis txhob tawg.

Daim ntawv thov

1. Daim ntawv thov ntawm Stainless Hlau Forgings hauv kev lag luam shipbuilding:

Cov nkoj khiav hauv dej tau ntau xyoo, tshwj xeeb hauv kev thauj mus los hauv hiav txwv. Qhov chaw ua haujlwm yog hnyav thiab corrosive. Yog li ntawd, stainless hlau yog dav siv hauv nkoj. Thaum ntxov li 1950s, speedboat kiv cua shafts tau forged nrog 20Crl3 hom martensitic stainless hlau, tsim. Tom qab ntawd, cov nkoj loj tau pib siv 06Crl7Nil2M02, austenitic stainless hlau, 06Cr25Ni5Mo2 duplex stainless hlau thiab 07Crl7Ni7Al nag lossis daus hardening stainless hlau los ua cov kiv cua; nkoj cav tso tshuab tau ua los ntawm 06Crl7Nil2Mo2 steel; turbine hniav yog ua los ntawm 12CrMo thiab 05Crl7Ni4Cu4Nb nag lossis daus hardening hlau; Ua los ntawm Cr-Ni austenitic stainless hlau; ua los ntawm 06Crl9Nil0 thiab 06Crl7 steel rau cov khoom siv hauv chav ua noj; ua los ntawm 06Crl8Ni9 thiab 06CH7 steel rau thauj khoom noj, tshuaj tankers thiab tub yees lub nkoj plhaub; Cr-Ni austenite nrog kev ua haujlwm kub tsis zoo rau cov nqa LNG Ua los ntawm cov hlau tsis muaj steel; minesweeper submarines yog ua los ntawm 022Cr21Nil7Mo2N thiab 022Cr22Nil3Mo3N steel; marine shafts thiab kub exchangers yog ua los ntawm 022Cr22Nil3Mo2N steel; patrol nkoj propellers, propulsion shafts, rudders, thiab lwm yam. yog ua los ntawm 06Cr25Ni6Mo3CuN steel.

2. Daim ntawv thov ntawm Stainless Hlau Forgings nyob rau hauv aerospace thiab aviation:

Aerospace thiab aviation muaj ib puag ncig hnyav thiab muaj zog corrosiveness, yog li stainless hlau yog dav siv nyob rau hauv aerospace thiab aviation industries. Feem ntau ntawm cov dav hlau thiab dav hlau yog ua los ntawm stainless hlau. Hauv kev lag luam aerospace, austenitic stainless hlau 06Crl8Ni9, 12Crl7Ni7, 06Crl8NillNb, 06Crl8Nil0Ti, 06Cr21Ni6Mn9N, thiab lwm yam. tuaj yeem siv rau cov tsheb loj tso tawm cov kua dej, cov hlab ntsha muaj zog qis thiab kub siab; tso pa tawm nyob ib ncig ntawm lub cav, foob pob hluav taws roj tso tsheb hlau luam thiab cov khoom siv siab (xws li cov pas nrig, claws, pins, thiab lwm yam) tuaj yeem xaiv martensitic stainless hlau 12Crl3, 20Crl3, 14Crl7Ni2 thiab 102Crl7Mo (9Crl8Mo) thiab lwm yam.

Hauv kev lag luam aviation, ntau cov nag lossis daus hardening stainless hlau yog siv nyob rau hauv lub tshuab ua haujlwm ntawm lub dav hlau, xws li 04Crl3Ni8Mo2Al, 05Crl5Ni5CuNb, 05Crl7Ni4Cu4Nb, AM350, A{{12}{B, thiab lwm yam. 13}} dav dav dav dav dav siv 05Crl5Ni5CuNb steel. Austenitic stainless hlau forgings xws li 20Crl3Mn9Ni4 thiab 06Crl9Nil0NbN tuaj yeem siv rau hauv aero-engine exhaust manifolds, ceg kav dej, thiab turbo compressor cua kub kav, thiab Cr-Ni xws li 12021 NiSTi tuaj yeem siv rau hauv aero-engine chamber casings, phab ntsa thiab aircraft qhov chaw. Duplex stainless hlau hloov austenitic stainless hlau xws li 12Crl8Ni9Ti.
