Titanium alloy precision casting tshuab siv

Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, titanium casting tshuab yog ntau thiab ntau tus paub tab, terbium alloy qhov kev ua tau zoo heev tau lees paub. Titanium casting zoo txuas ntxiv txhim kho, cov nqi tsim khoom maj mam txo, yog li kev lag luam aviation, aerospace, marine thiab tshuaj lom neeg kev lag luam tau pib siv ntau cov titanium castings, titanium alloy peev casting tshuab tau siv ntau thiab ntau dua.

Kev siv hauv kev lag luam aerospace

Txij xyoo 1990s mus rau tom ntej, ntawm lub dav hlau tshiab nyob hauv daim jr ntau qhov loj loj nyias-walled tag nrho casting ntawm titanium rooj kub zoo li tus qauv. aircraft Airbus A380 sau npe hauv Tuam Tshoj nrog tus nqi 45I txog 65t / ncej. Tus nqi ntawm titanium siv hauv Duoyin aircraft suav rau nws qhov hnyav tag nrho ntawm l 5% 17%. F22 fighter fuselage qauv nrog titanium 361 / ntev lance, uas muaj xws li ib tug loj tus naj npawb ntawm titanium alloy castings alloy casting technology kev loj hlob yoog mus rau lub dav hlau thiab lub cav Cheebtsam yuav tsum tau los txo qhov hnyav ntawm raw cov ntaub ntawv, siab siv tus nqi, tsis tshua muaj nqi ua, lub kev thov rau lub voj voog luv luv.

Nyob rau hauv txawv teb chaws, aviation xyaw tau dav siv nyob rau hauv loj-scale complex tag nrho cov titanium alloy precision casting ntawm kiv cua magazine thiab intermediary magazine thiab lwm yam loj Cheebtsam. Ua tau zoo tsim F a 100, CFM a 56, CF6-80, F a 119 aircraft engine, xws li loj nyias bib tag nrho titanium box intermediary magazine, kiv cua magazine, high-pressure pressurized tshuab magazine thiab lwm yam castings, qhov loj txoj kab uas hla tau mus txog 1300mm los yog li ntawd, cov phab ntsa me me ntawm tsawg dua 3ram, qhov tseeb qhov tseeb ntawm CT6 qib cT7, metallurgical zoo yog siab. Kev vam meej ntawm cov precision castings, zoo heev txhim kho kev ua tau zoo ntawm lub cav, txo qhov hnyav ntawm lub dav hlau. Kev siv cov khoom siv tau zoo dua qub, ua kom luv luv ntawm qhov chaw tsim khoom, txo cov nqi tsim khoom ntawm cov tshuab dav hlau.

US F-22 aircraft siv ntau tshaj 70 titanium alloy castings, 50% ntawm lub tis yog tsim los ntawm titanium rooj kub castings. Kev siv cov precision casting ntawm titanium alloy qhov chaw: rudder tsav bracket, shielding phaj, tis sidewalls ua ntej thiab tom qab lub mount, aileron backplane, cua kom tsawg oblique thav duab thiab lwm yam rau loj structural qhov chaw.

Txhim kho qhov rigidity ntawm cov khoom, txo cov nqi tsim kho. Nyob rau hauv lub va 22 aircraft siv nyob rau hauv tag nrho cam khwb cia titanium kub hloov adapter. Nws yog thawj 43 qhov me me thiab 536 fasteners tsim los ntawm aluminium forgings, hloov mus rau tag nrho cov cam khwb cia titanium alloy, kom tag nrho cov nqi tsim khoom siv dav hlau txo los ntawm 30%, kev ua haujlwm thiab kev teeb tsa lub sij hawm txo los ntawm 62%, txo qis kev tsim khoom.
