Titanium hlau rau vuam yog cov khoom siv tseem ceeb hauv kev lag luam vuam siab heev, thiab siv dav hauv kev siv dav hlau, kev kho mob cog, thiab tshuaj tiv thaiv- corrosion ntawm lwm cov ntawv thov tseem ceeb. Qhov tseeb ntawm cov vuam ua nws tus kheej ncaj qha cuam tshuam rau lub zog thiab plasticity ntawm cov welded sib koom ua ke thiab corrosion kuj. Piv nrog cov hlau zoo tib yam welding hlau, nws muaj cov txheej txheem nruj hauv kev tshuaj xyuas cov khoom siv raw, kev ua tiav, thiab kev tswj ib puag ncig.
Cov txheej txheem ntau lawm: Nrog rau qhov pib no High purity titanium raw khoom tswj nruj feem ntau raws li ASTM tus qauv siv daim txhuam cev titanium lossis titanium alloy master batch, impurity cov ntsiab lus tswj hauv ppm. Cov txheej txheem melting yog ib qho tseem ceeb ntawm kev tswj cov ntaub ntawv, Cov txheej txheem tseem ceeb yog lub tshuab nqus tsev siv tau arc melting (VAR) tshuab, qee qhov kev ua haujlwm siab yuav raug zam los ntawm lub tshuab nqus tsev induction melting (VIM). Cov txheej txheem VAR muaj peev xwm ua tau zoo los ntxuav cov khoom sib txawv xws li oxygen, nitrogen thiab hydrogen los ntawm ntau lub voj voog yaj - hydrogen pawg feem yuav tsum tsawg dua lossis sib npaug li 0.005%, oxygen Tsawg dua lossis sib npaug li 0.13% Txawm tias qhov hloov pauv me me hauv cov ntsiab lus no tuaj yeem ua rau muaj kev sib cais ntau dua hauv cov hlau tsis muaj zog, txawm tias cov hlau tsis muaj zog, thiab cov hlau tsis muaj zog. welding sib koom ua tsis tiav.
Thaum lub sijhawm ua haujlwm kub, cov titanium melted ingots tau ua tiav rau hauv titanium rods lossis hlau blanks los ntawm forging, dov, thiab lwm yam txheej txheem. Kev ua haujlwm kub yuav tsum nruj me ntsis tswj nyob rau hauv theem hloov pauv kub ntawm titanium alloy kom tsis txhob overheating lossis overburning. Cov kauj ruam no tsis yog tsuas yog txiav txim siab qhov loj me ntawm cov khoom siv (zoo tagnrho nplej txoj kab uas hla tswj tau qis dua 50 μ m), tab sis tseem cuam tshuam rau kev ua haujlwm ntawm kev ua haujlwm txias tom ntej. Los ntawm kev ua kom zoo dua cov kev ua haujlwm kub kom tsim tau cov qauv zoo sib xws thiab zoo equiaxed siv lead ua, qhov kev pheej hmoo ntawm cov hlau tawg thaum cov txheej txheem tom ntej tuaj yeem txo qis, thiab kev tsim khoom tuaj yeem txhim kho.
Kev kos duab txias yog cov txheej txheem tseem ceeb ntawm kev tsim cov titanium welding hlau, uas yuav tsum tau muaj ntau yam txheej txheem incremental. Lub deformation ntawm txhua tus txheej txheem yog tswj ntawm 15% -25% kom tsis txhob muaj cov khoom brittleness tshwm sim los ntawm ntau deformation nyob rau hauv ib txoj kev. Vim yog qhov sib txuam ntawm cov kev ntxhov siab nyob hauv cov khoom siv thaum lub sij hawm kev kos duab, kev kho mob nruab nrab annealing yuav tsum tau tom qab qhov tseem ceeb dhau. Lub annealing yog ua nyob rau hauv lub tshuab nqus tsev lossis argon siab purity tiv thaiv huab cua ntawm qhov kub ntawm 600-700 degree. Lub sijhawm tuav tau hloov kho raws li txoj kab uas hla, uas tuaj yeem rov qab tau cov yas ntawm cov khoom thiab tshem tawm DBs thiab kev ntxhov siab sab hauv. Nws tseem tuaj yeem tiv thaiv qhov oxidation saum npoo los ua cov txheej txheem nkig, thiab kev ua haujlwm tas mus li yog paub tseeb.
Kev ua kom zoo dua qub thiab kev sim ua tiav hauv cov khoom tiav yog cov kab kawg ntawm kev tiv thaiv. Kev kho deg yuav tsum tau tshem tawm cov pa phem xws li oxide nplai thiab cov roj stains los ntawm cov txheej txheem xws li tshuab polishing, acid pickling, thiab passivation los xyuas kom meej qhov smoothness ntawm vuam hlau nto thiab zam qhov tsim ntawm pores thaum vuam. Kev tswj qhov tseeb ntawm qhov yuav tsum ncav cuag ± 0.01mm, thiab qhov ncaj thiab winding kev ua tau zoo yuav tsum tau sim los ntawm cov cuab yeej tshwj xeeb los xyuas kom meej tias tag nrho cov yob ntawm vuam hlau tsis muaj dabtsi yog khoov thiab tsis sib npaug. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua cov kev soj ntsuam spectral, eddy tam sim no kuaj, thiab kev ua tau zoo ntawm cov khoom ua tiav los xyuas kom meej tias cov tshuaj muaj pes tsawg leeg, qhov tsis xws luag, tensile lub zog, thiab lwm yam kev ntsuas ua tau raws li cov qauv, thiab cov kev ua tau zoo ntawm tag nrho cov yob ntawm vuam hlau yog zoo ib yam, ua tau raws li qhov yuav tsum tau ua haujlwm ruaj khov ntawm cov khoom siv vuam tsis siv neeg thiab muab cov cuab yeej siv tau ruaj khov rau kev tsim khoom siab {{4}.
