Cold-drawn seamless steel yeeb nkabyog aprecision txias-draw seamless steel yeeb nkabnrog rau qhov siab qhov tseeb thiab qhov chaw zoo rau cov qauv siv tshuab thiab cov khoom siv hydraulic.Xaiv cov yeeb nkab seamless steel yeeb nkablos tsim cov qauv siv tshuab lossis cov khoom siv hydraulic tuaj yeem txuag lub sijhawm ua haujlwm, txhim kho cov khoom siv thiab txhim kho cov khoom zoo.
Yuav kom tau txais seamless steel kav nrog me me thiab zoo dua, txias dov, txias kos duab los yog ob txoj kev yuav tsum tau saws.Txias dov feem ntau yog ua los ntawm ob-siab zeb, thiab seamless steel kav yog dov nyob rau hauv ib tug annular pass tsim los ntawm ib tug txawv txawv cross-section ncig groove thiab ib tug ruaj conical plug.Kev kos duab txias feem ntau yog ua los ntawm 0.5 ~ 100T ib leeg-chain lossis ob-chain txias tshuab kos duab.
2. Cov yeeb nkab txias-daws seamless steel yeeb nkab yog cov khoom lag luam uas tau tshwm sim nyob rau hauv xyoo tas los no, feem ntau yog vim lub qhov thiab sab hauv phab ntsa qhov ntev muaj qhov ua siab ntev thiab roughness.
Nta ntawmtxias-draw (dov) seamless steel yeeb nkab:
1. Cov kab me me sab nraud.2. High precision yuav siv tau rau me me batch ntau lawm 3. High precision ntawm txias drawn (dov) khoom thiab zoo nto zoo.4. Qhov chaw hla ntawm seamless steel yeeb nkab yog qhov nyuaj dua.5. Kev ua tau zoo ntawm seamless steel yeeb nkab yog superior, thiab cov hlau kuj tseem ntom.Seamless steel kav rau cov qauv(GB / T8162-2008) yog seamless steel kav rau cov qauv dav dav thiab cov khoom siv tshuab.Nws yog ib hom seamless steel yeeb nkab cais raws li nws cov kev siv sib txawv.Cov kev siv muaj xws li txhua yam ntawm cov qauv seamless steel kav siv nyob rau hauv cov qauv dav dav thiab cov qauv siv tshuab, nrog rau ntau qhov kev lag luam xws li kev tsim kho, tshuab, tsheb thauj mus los, aviation, kev siv roj, thiab lwm yam.
Qhov sib txawv tseem ceeb ntawm annealing thiab normalizing:
1. Cov cua txias ntawm normalizing yog me ntsis sai dua li ntawm annealing, thiab cov degree ntawm supercooling yog siab dua 2. Lub microstructure tau tom qab normalizing yog finer, thiab lub zog thiab hardness yog siab tshaj li ntawm annealing.
Kev xaiv ntawm annealing thiab normalizing:
1. Normalizing feem ntau yog siv es tsis txhob annealing rau low-carbon seamless steel kav nrog cov ntsiab lus carbon tsawg dua 0.25%.vim
Txhawm rau kom txias sai dua, nws tuaj yeem tiv thaiv cov yeeb nkab uas tsis muaj cov pa roj carbon seamless steel los ntawm kev sib cais raws li cov ciam teb thiab tsiv mus rau peb zaug ntawm carburization txhawm rau txhim kho qhov txias deformation ntawm cov khoom stamping;Normalizing tuaj yeem txhim kho hardness ntawm steel
Machinability ntawm carbon seamless steel yeeb nkab;Thaum tsis muaj lwm txoj kev kho cua sov, normalizing tuaj yeem ua kom zoo dua cov nplej thiab txhim kho lub zog ntawm cov pa roj carbon tsawg seamless steel yeeb nkab.
2.Medium-carbon txias-draw seamless steel yeeb nkabnrog cov ntsiab lus carbon ntawm 0.25 thiab 0.5% kuj tuaj yeem hloov los ntawm normalizing
Hloov cov annealing, txawm hais tias lub hardness ntawm txias-draw seamless steel yeeb nkab ntawm nruab nrab carbon steel ze rau lub sab sauv txwv ntawm cov ntsiab lus carbon yog me ntsis siab tom qab normalizing siab, tab sis nws tseem yuav raug txiav, thiab tus nqi normalizing yog tsawg thiab cov productivity yog siab. .3.Cov yeeb nkab txias-daws seamless steel yeeb nkab nrog cov ntsiab lus ntawm 0.5 thiab 0.75% muaj cov ntsiab lus carbon siab,
Lub hardness tom qab normalizing yog ho siab dua li ntawm annealing, yog li nws yog ib qho nyuaj rau nqa tawm txiav, yog li feem ntau siv tag annealing kom txo hardness thiab txhim kho machinability.
4. Cov pa roj carbon ntau lossis cov cuab yeej hlau nrog cov ntsiab lus carbon ＞ 0.75% ntawm cov yeeb nkab txias seamless steel feem ntau siv pob tshuaj annealing yog siv los ua kev kho cua sov ua ntej.Yog hais tias muaj network thib ob cementite, nws yuav tsum tau nqa tawm thawj zaug tua hluav taws.Annealing yog ua kom sov cov yeeb nkab uas tsis muaj seamless steel rau qhov kub thiab txias thiab khaws cia rau qee lub sijhawm, txheej txheem kev kho cua sov nrog qeeb txias.Kev ua kom txias qeeb yog qhov tseem ceeb ntawm kev sib tsoo, thiab kev sib tsoo thiab kev kos duab txias tsis yog Feem ntau, cov yeeb nkab steel seam txias kom qis dua 550 ℃ hauv qhov cub.Annealing yog siv dav siv ntau qhov kev kho cua sov feem ntau yog siv los ua kev npaj hauv kev tsim cov cuab yeej lossis cov khoom siv hluav taws xob Kev kho cua sov yog npaj tom qab casting, forging thiab vuam thiab ua ntej txiav (rough) kom tshem tawm cov txheej txheem dhau los.Qee qhov tsis xws luag los ntawm cov txheej txheem , thiab npaj rau cov txheej txheem tom ntej.
Annealing lub hom phiaj: ① txo qhov hardness ntawm txias-draw seamless steel yeeb nkab los pab txhawb machining;② Tshem tawm ntau hom Kev Nyuaj Siab los tiv thaiv deformation ntawm txias-draw seamless steel yeeb nkab;③ Kho cov nplej ntxhib thiab txhim kho cov qauv sab hauv Npaj rau kev kho cua sov zaum kawg.
