Titanium alloy nqaim nqaim nqaim

 

Titanium alloy nqaim nqaim yog cov ntawv hlau cov khoom lag luam nrog cov qauv ntawm cov kab tiaj, feem ntau yog nyob rau hauv daim ntawv ntawm cov tiaj tiaj, thiab lwm yam siv hauv kev lag luam.

Nws yog lub teeb ci ntsa iab, lub zog siab thiab zoo heev corrosion tsis kam, uas ua rau nws sawv hauv cov chaw hnyav.

 

Muaj cov ntshiab titanium yog faib rau hauv cov qib sib txawv raws li nws cov ncauj lus los hauv ntiaj teb, xws li GR1, Gr2 thiab Gr3. Ntawm lawv, Gr2 yog qib kev lag luam feem ntau. Nws cov neeg kho tshuab zog thiab hardness nce nrog kev nce impurity cov ntsiab lus (xws li oxygen thiab nitrogen), tab sis nws cov yas thiab tawv txo qis.

Cov yam ntxwv zoo no pab cov kab mob titanium ua si ib lub luag haujlwm tseem ceeb hauv teb, lawv tau siv los ua cov qauv kev txhim kho, thiab cov kws kho mob, thiab kev kho tshuaj ua haujlwm, thiab kev tiv thaiv tshuaj thiab kev tiv thaiv kev ua haujlwm rau cov khoom loj.

 

Cov txheej txheem ua muaj ntau yam sib txawv, suav nrog shearing, rolling, vuam, vuam, vuam, rending raws li cov cai yuav tsum tau ua kom pom kev ua tau zoo thiab zoo nkauj.

 

 

Cov kev qhia tshwj xeeb ntawm cov pitanium phaj tau faib rau ntau qhov ntev raws li cov qauv sib txawv raws li tuab, dav thiab ntev. ‌

Cov kev qhia tshwj xeeb ntau yog raws li hauv qab no:

Thickness luv:

0.3-0.5mm: Dav tsis tshua dhau 1000mm, ntev tsis pub dhau 2000mm

0.6-1.0 Hli: Dav tsis tau tshaj 1200 hli, ntev tsis dhau 2000 mm

1.0-6.0 hli: Dav tsis tau tshaj li 2000 mm, ntev txog 6000 hli

5.0-8.0 hli thiab 8.0-50.0 hli: Dav tsis tau tshaj 2000 mm, ntev txog 6000 mm

 

Ib qho ntxiv, cov tuab tuab hauv Tshuag ntau ntawm 0.8mm rau 16mm, thiab rau qee cov ntawv thov xws li cua sov kom zoo li, nce mus txog 60 hli

 

Qhov dav ntau ntawm yog: nws yog feem ntau ntawm 400 hli thiab 2000 mm. Piv txwv li, qhov dav ntawm daim nyias nyias nyias (0.3-6.0 hli) yog 400-2000 mm, thiab qhov dav ntawm tuab cov paib (4.7-60.0 hli) tuaj yeem ncav cuag 1050 hli.

Qhov ntev txwv: Tus qauv ntev ntev los ntawm 1000 mm mus rau 6000 mm. Tshwj xeeb, qhov ntev ntawm nyias daim hlau yog 1000-3000 mm, thiab qhov ntev ntawm cov paib tuab mus rau 6000 mm kom tau raws li cov cai ntawm cov khoom loj.
