I. Hom Tsis yog-Txoj kev kuaj kev puas tsuaj thiab cov xwm txheej siv tau
1. Kev Ntsuas Ultrasonic (UT)
Muaj feem xyuam rau: Tshawb xyuas cov kab nrib pleb sab hauv, xws li qhov tsis xws luag xws li delamination, suav nrog, thiab porosity.
Lub hauv paus ntsiab lus: Siv siab - zaus suab nthwv dej propagating nyob rau hauv cov yeeb nkab steel, lub teeb pom kev tshwm sim yog tsim thaum ntsib cov kab nrib pleb los yog lwm yam khoom siv tsis tu ncua. Qhov chaw thiab qhov loj ntawm qhov tsis xws luag yog txiav txim siab los ntawm kev txheeb xyuas cov echoes.
Qhov zoo: Muaj zog nkag mus rau lub zog; tuaj yeem ntes micro- tawg ntawm phab ntsa thickness kev taw qhia (qhov tsis xws li me me li 0.1 hli tuaj yeem txheeb xyuas tau).
Standard Basis: GB / T 5777 "Ultrasonic Test Method rau Seamless Steel Tubes".
2. Magnetic Particle Testing (MT)
Muaj feem xyuam rau: Tshawb xyuas qhov chaw thiab nyob ze - cov kab nrib pleb hauv cov khoom siv ferromagnetic, xws li khawb, folds, thiab qaug zog tawg.
Lub hauv paus ntsiab lus: Siv cov hlau nplaum sib nqus rau saum npoo ntawm cov yeeb nkab steel tsim kom muaj qhov sib nqus sib nqus ntawm qhov tawg, nyiam cov hmoov sib nqus thiab nthuav tawm cov kab sib nqus.
Qhov zoo: siab rhiab heev; muaj peev xwm txheeb xyuas cov kab nrib pleb tsuas yog ob peb micrometers dav.
Lus Cim: Tsuas yog siv tau rau cov ntaub ntawv ferromagnetic xws li carbon steel thiab hlau alloy; tsis haum rau austenitic stainless hlau.
3. Eddy Current Testing (ET)
Cov ntawv thov: Tshawb xyuas qhov chaw thiab nyob ze - cov kab nrib pleb hauv cov khoom siv hluav taws xob, tshwj xeeb tshaj yog tsim rau kev tshuaj ntsuam online sai.
Lub hauv paus ntsiab lus: Eddy tam sim no yog tsim los ntawm electromagnetic induction; Cov kab nrib pleb ua rau muaj kev hloov pauv ntawm cov eddy tam sim no, uas yog tom qab ntawd ntes los ntawm lub ntsuas.
Qhov zoo: Tsis tas yuav tsum muaj tus neeg sawv cev coupling; ceev nrhiav kom tau ceev; haum rau automated ntau lawm kab.
Kev txwv: txwv qhov tob kom pom (feem ntau<5mm); insensitive to deep cracks.
4. Kev kuaj hluav taws xob (RT)
Daim Ntawv Thov: Tshawb xyuas qhov tsis xws luag hauv volumetric xws li porosity thiab inclusions; tsis muaj zog tawg nrhiav kom tau muaj peev xwm.
Lub hauv paus ntsiab lus: Siv X-rays lossis gamma rays kom nkag mus rau cov kav hlau; Cov qauv sab hauv yog tso tawm los ntawm cov yeeb yaj kiab lossis cov duab digital.
Qhov zoo: Cov txiaj ntsig zoo; cov ntaub ntawv duab tuaj yeem khaws cia mus tas li.
Lus Cim: Tsawg tus nqi rau cov kab nrib pleb (xws li cov kab nrib pleb ntev); yuav tsum muaj ntau-angle irradiation.
5. Kev Xeem Penetrant (PT)
Daim ntawv thov: Tshawb xyuas qhov chaw- qhib cov kab nrib pleb hauv cov khoom tsis yog- ntxeem tau, haum rau cov khoom tsis yog- cov khoom sib nqus xws li stainless hlau thiab tooj liab alloys.
Txoj Cai: Penetrant yog siv rau saum npoo, seeping rau hauv qhov tawg. Tom qab ntxuav, tus tsim tawm yog siv los qhia qhov tsis xws luag.
Qhov zoo: Kev ua haujlwm yooj yim, tus nqi qis, haum rau cov duab nyuaj.
II. Cov txheej txheem tshuaj xyuas pom zoo
1. Kev Tshawb Fawb Txog Kev Pom Kev Ua Ntej: Saib xyuas qhov chaw ntawm cov yeeb nkab steel kom pom tseeb cov khawb, qhov bulges, xeb pits, lossis lwm qhov chaw tsis txaus ntseeg.
2. Xaiv Txoj Kev Tsim Nyog Kev Sib Koom:
Deg Cracks → Sib nqus particle los yog kev ntsuam xyuas penetrant yog nyiam;
Sab hauv Cracks → Ultrasonic kuaj yog nyiam;
Online Siab -Kev Ntsuas Kev Ceev → Eddy qhov ntsuas tam sim no tuaj yeem siv tau.
3. Ua raws li National Standards: Cov txheej txheem xeem yuav tsum ua raws li cov qauv kev lag luam xws li GB/T 8162 thiab GB/T 8163 kom ntseeg tau tias muaj txiaj ntsig thiab siv tau.
4. Cov Neeg Ua Haujlwm Kev Tsim Nyog: Cov neeg ua haujlwm xeem yuav tsum tuav cov ntawv pov thawj kev xeem uas tsis muaj kev puas tsuaj (xws li RT, UT, MT, thiab lwm yam) thiab ua raws li cov txheej txheem nruj me ntsis.
III. Kev txhim kho ntawm Cov Kev Ntsuas Tshiab
1. Kev Ntsuas Ntsuas Ntsuas Raws li Kev Ua Duab: Piv txwv li, patented thev naus laus zis tau thov los ntawm Jinzhengyang Yeeb Nkab Kev Lag Luam tuaj yeem txo qhov kev kuaj pom tsis zoo nyob rau hauv ciam teb - cov cheeb tsam rhiab heev los ntawm kev txheeb xyuas thaj chaw ntawm kev hloov pauv sai ntawm phab ntsa tuab thiab tsim cov ntaub ntawv keeb kwm tsis zoo.
2. Automated Flaw Detection Lines: Cov koom haum xws li Steel Research Institute Nake tau muab tag nrho automated ultrasonic, eddy tam sim no, thiab sib nqus flux leakage flaw detection kab rau ntau pua lub tuam txhab, ua tau zoo thiab raug kuaj.
