Laser Cladding Remanufacturing Technology
Mar 26, 2024
Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb niaj hnub, thev naus laus zis thiab kev lag luam, qhov chaw ua haujlwm ntawm cov khoom thiab cov khoom siv tau dhau los ua ntau dua, thiab cov kev xav tau ntawm cov khoom saum npoo tau nce siab dua. Yog li ntawd, qhov seem ntawm qhov seem tau nce ntau heev. Cov khoom uas feem ntau yog muab pov tseg vim qhov tsis ua hauj lwm nto muaj xws li: rotor hniav, ncej qhov chaw, iav qhov chaw, pwm, thiab lwm yam.
Cov khoom uas tsuas yog qhov kev puas tsuaj tuaj yeem kho tau raws li qhov kev ua tau zoo ntawm tag nrho cov khoom ua tau raws li kev ua haujlwm. Yog tias cov khoom seem raug tshem tawm vim kev ua tsis raug lossis kev pabcuam kev puas tsuaj tuaj yeem kho tau, tsis tsuas yog tuaj yeem rov qab tau nyiaj txiag loj thiab lub sijhawm poob, tab sis kev siv cov peev txheej tuaj yeem txhim kho.
Cov txheej txheem tam sim no rau kev kho qhov chaw muaj xws li laser cladding, nqus brazing, nqus txheej, tungsten inert gas welding (TIG) thiab plasma cladding kho. Laser cladding yog raws li nyob rau hauv cov kev ua hauj lwm tej yam kev mob ntawm lub workpiece, cladding hlau los yog cov hlau tsis muaj hlau nrog ntau yam qauv tsim los npaj cov txheej txheej uas muaj cua sov-resistant, corrosion-resistant, hnav-resistant, oxidation-resistant, qaug zog-resistant los yog optical. , hluav taws xob thiab magnetic zog.
Laser cladding yog txheej txheem cua txias sai. Thaum lub sij hawm cladding txheej txheem, lub tshav kub input rau lub kho workpiece yog me me, lub tshav kub cuam tshuam cheeb tsam me me, lub cladding txheej muaj ib tug zoo qauv, thiab nws yog ib qho yooj yim mus siv automation. Yog li ntawd, laser cladding yog siv los kho lub rotor. Lwm qhov chaw muaj qhov zoo dua li lwm txoj hauv kev. Laser cladding thev naus laus zis daws cov teeb meem kev lag luam xws li thermal deformation thiab thermal qaug zog kev puas tsuaj uas tsis tuaj yeem tshwm sim thaum ua haujlwm thermal xws li tsoos hluav taws xob vuam thiab argon arc vuam. Nws kuj daws tau qhov sib txuas ntawm lub zog ntawm cov txheej thiab cov substrate thaum lub sijhawm ua haujlwm txias xws li tsoos electroplating thiab txau. Kev tsis sib haum xeeb tsis zoo, uas muab txoj hauv kev zoo rau kev kho saum npoo.
Taw qhia rau Laser Cladding txheej txheem
Rau cov khoom siv tshuab nrog hnav, corrosion, creep, qaug zog, thiab tawg tsis ua haujlwm, laser cladding tshuab yog siv los ua ib txhij pub cov hmoov txhuas rau hauv lub pas dej molten thiab ceev ceev kom tsim ib txheej cladding nrog cov khoom tshwj xeeb. Cov txheej txheej cladding tsis muaj qhov pores thiab tawg tsis xws luag, thiab qhov hardness ntau yog 20 ~ 60HRc, uas tuaj yeem ua tau raws li ntau yam kev ua haujlwm thiab kev ua haujlwm. Haum rau cladding / remanufacturing ntawm ntau yam loj qhov chaw nrog complex duab, restores loj thiab kev ua tau zoo ntawm qhov chaw ua tsis tau tejyam, kho kom zoo dua nto thaj chaw, thiab ncua kev pab cuam lub neej.
Laser Cladding txheej txheem yam ntxwv

Siv cov hmoov hlau tshwj xeeb, txheej txheej cladding tuaj yeem hnav tsis kam, corrosion kuj, qaug zog thiab lwm yam khoom;
Lub cladding txheej txheej muaj ib tug ua tiav zoo-grained qauv thiab zoo heev lub zog thiab toughness.
Daim ntawv thov ntawm Laser Cladding Technology
1. Kho ntawm rotor hniav
Rotor blades yog qhov tseem ceeb uas cuam tshuam ncaj qha rau kev ua haujlwm ntawm lub cav, kev ntseeg siab thiab lub neej, thiab lawv cov haujlwm ua haujlwm hnyav heev thiab yooj yim rau kev puas tsuaj, yog li cov kev xav tau ntawm cov khoom siv tau zoo heev. Daim ntawv thov ntawm laser cladding technology ntawm rotor hniav tau kawm tau zoo, uas kuj muab ib tug zoo prerequisite rau nws daim ntawv thov nyob rau hauv kho.
2. Kev kho cov ncej ncej
Feem ntau, cov laj thawj tseem ceeb ntawm kev ua tsis tiav ntawm cov ncej ncej muaj xws li ncej deformation, ncej tawg, thiab ncej nto tsis ua haujlwm. Siv lub zog hluav taws xob laser cladding kho tshuab, txheej txheej ntawm cov hlau-raws li cov khoom siv hlau tuaj yeem ua laser cladded ntawm qhov ua tsis tiav ntawm cov ncej, kom cov txheej txheej clad alloy muaj cov khoom zoo, thiab cov khoom seem tuaj yeem rov qab siv dua. .
3. Pwm kho
Pwm plays lub luag haujlwm tseem ceeb hauv casting molding thiab yas molding ua. Nws cov txheej txheem tsim khoom yog complex, lub voj voog ntau lawm ntev, thiab cov nqi ua haujlwm siab. Yog li ntawd, kev kho thiab rov siv cov pwm ua tsis tau zoo yog qhov tsis muaj txiaj ntsig zoo rau kev lag luam. Laser cladding tau dhau los ua qhov kev tshawb fawb hotspot rau kho pwm thiab tau nyiam ntau yam.
Cov txheej txheem ntawm laser cladding los kho qhov hnav ntawm cov pwm tuaj yeem ua tiav raws li hauv qab no: siv lub tshuab hluav taws xob laser siab nrog lub zog tas li P thiab cov hmoov kub ntws los ua qhov tshwm sim ntawm cov pwm saum npoo tib lub sijhawm, ib feem ntawm Qhov teeb meem teeb pom kev zoo, ib feem ntawm lub teeb yog absorbed, thiab tam sim ntawd Tom qab lub zog absorbed tshaj ib qho tseem ceeb, cov hlau melts los tsim ib tug molten pas dej ua ke, uas ces solidifies sai heev los ua ib tug metallurgically bonded cladding. Lub laser beam scans rov qab los kho cov pwm kab los ntawm kab thiab txheej los ntawm txheej raws li txoj kev muab los ntawm CAD daim ntawv thov kev txhim kho theem nrab. Hauv particular, kho pwm yuav luag tsis muaj reprocessing.
Daim ntawv thov teb:
Siv rau hauv hluav taws xob fais fab (steam turbine rotors, blades), mining (gears, laum bits, hydraulic rods), machinery (shafts, gears), petrochemicals (turbine discs, rotors, push rods), ships (crankshafts, engine blades, camshafts) , cov remanufactured qhov chaw ntawm locomotives (shafts, turbine blades, bogies, pistons), pwm (stamping dies, forging dies, die-casting dies) thiab lwm yam industries yog txhim khu kev qha zoo thiab muaj zoo economic thiab kev pab cuam.
