1. Khoom piav qhia
Titanium clad steel raj phaj rau tshav kub exchangeryog tsim los ntawm kev sib tsoo tawg, thiab cov txheej txheem ua haujlwm yog ASTM B898-11 Cov Txheej Txheem Tshwj Xeeb rau Reactive thiab Refractory Hlau Composite Phaj. Kev tawg vuam feem ntau yog siv lub zog tsim los ntawm kev tawg tawg los yog cov yas deformation ntawm ntau tshaj ob hom khoom hlau, kom cov hlau sib txuas tuaj yeem ua tiav cov hlau sib txuas thiab tsim cov hlau sib xyaw tshiab. Cov txheej txheem vuam tawg uas siv hauv qhov project feem ntau suav nrog kev sib txuas ua ke.
Muaj ob txoj kev teeb tsa: txoj kev teeb tsa thiab txoj kev teeb tsa lub kaum sab xis.
2. Khoom nta
(1) Cov khoom shear, tensile zog, thiab tej yam khoom ntawm titanium/steel composite daim hlau npaj los ntawm tawg welding nyob rau hauv PTA project tau hloov tom qab simulated post weld tshav kub kev kho mob ntawm txawv kub.
(2) Cov txiaj ntsig tau pom tias lub zog tensile, lub zog tawm los thiab lub zog shear ntawm titanium / steel puas phaj raug txo los ntawm simulated PWHT, thaum lub elongation thiab cov khoom cuam tshuam tau txhim kho tom qab simulated PWHT.
(3) SPWHT② (615 ± 10) degree × 3 h ntxiv rau (565 ± 15) degree × Lub zog ntawm 8.7h ntawm cov khoom tensile, shear zog, thiab cov khoom ntawm cov phaj sib xyaw yog ntau dua SPWHT ① (565 ± 15) degree × 13 h
3. FAQ
Nyob rau hauv cov txheej txheem ntawm tawg vuam, cov txheej txheem txav ntawm 1 hli ultra-thin cladding phaj txawv ntawm qhov loj dua los yog sib npaug rau 4 hli cladding phaj: ua ntej, nws tsis yooj yim rau nyias cladding phaj kom nws cov duab thaum lub sij hawm tawg. txheej txheem. Qhov thib ob, qhov zoo ntawm nyias titanium clad steel raj phaj rau cov khoom siv hluav taws xob sib txawv yog qhov me me, thiab lawv tuaj yeem ncav cuag kev kub ceev; Cov lus teb rau detonation siab kuj ceev heev, yog li lub siab ntawm kev sib tshuam ntawm cov pa roj thiab cov phaj cladding tej zaum yuav muaj ib tug me ntsis instantaneous poob. Yog li ntawd, qhov nrawm ntawm daim hlau nyias tsis zoo ib yam li cov phaj tuab, ua rau muaj kev vibration thiab flutter ntawm nyias daim hlau hauv davhlau. Tsis tas li ntawd, cov lus teb ntawm cov phaj nyias mus rau lub zog deceleration kuj ceev heev. Lub sij hawm ntawm kev cuam tshuam siab tau los ntawm clad daim hlau nyob ntawm lawv cov thickness. Qhov cuam tshuam siab tau los ntawm cov phaj tuab tuab yuav siv sij hawm ntev, uas txhais tau hais tias lawv tsis xav tau qhov kev kub ceev ntawm cov phaj nyias. Lub thinner lub clad phaj yog, qhov nrawm dua qhov kev poob siab yoj los ntawm nws qhov chaw mus txog qhov sib txuas ntawm vuam, uas yuav ua rau cov txheej txheem vuam tsis tiav thiab tsis tiav txias ntawm lub interface.
Lub interface ntawm cladding phaj yog tawg vim xav txog. Qhov no yog vim qhov nce ntawm lub zog tawg thiab qhov txo qis ntawm detonation tshaj tawm tom qab hloov kho. Txawm li cas los xij, kev tsim cov interface melting block tshwm sim los ntawm qhov nce ntawm nws qhov kev cuam tshuam muaj peev xwm tsis xav tias yuav pom nyob rau hauv qhov tseeb ntau lawm, uas xav tau ntau qhov kev ua pov thawj thiab kev tshawb fawb ntxiv.
