Daim ntawv thov

High kub alloy castings yog dav siv nyob rau hauv aerospace kev lag luam, hluav taws xob fais fab, tsheb, metallurgy, iav manufacturing, atomic zog thiab lwm yam kev lag luam teb. Aerospace thiab hluav taws xob fais fab yog lub ntsiab nqes dej ntawm superalloy (ntau tshaj 70 feem pua). Ntxiv nrog rau cov cav aero thiab naval gas turbines, superalloys kuj tau siv dav hauv tshuab aerospace, roj turbines, automotive turbocharging, nuclear zog, petrochemicals, metallurgy.

Kub ntau lawm, textile, iav manufacturing thiab ntau lwm yam pej xeem teb.

Superalloys tau siv nyob rau hauv aircraft cav txij li thaum lawv yug los. Hauv cov tshuab dav hlau niaj hnub no, cov khoom siv superalloy yog siv.

Nws suav txog 40 feem pua ​​​​rau 60 feem pua ​​​​ntawm tag nrho qhov hnyav ntawm lub cav, thiab feem ntau yog siv rau plaub qhov kub kawg: combustion chamber, phau ntawv qhia, turbine hniav thiab turbine disk. Tsis tas li ntawd, nws kuj yog siv rau casing, nplhaib, afterburner thiab tail nozzle. thiab lwm qhov chaw. Kev nce qib ntawm lub cav yog txiav txim siab los ntawm nws qhov kev sib tw-rau-qhov hnyav piv ntsuas, thiab ua kom lub cav aviation roj turbine ua tiav kev ua haujlwm siab nrog me me thiab lub teeb yuag.

Qhov ntsuas yog siv cov roj kub siab dua. Thaum lub turbine inlet kub nce los ntawm 100 degree, qhov thrust-qhov hnyav piv ntawm aero-engine yuav nce li ntawm 10 feem pua. Tam sim no, qhov nruab nrab kub ntawm lub turbine inlet ntawm lub siab tshaj plaws thib plaub-tiam xyaw nrog ib tug thrust-rau-hnyav piv ntawm 10 nyob rau hauv txawv teb chaws lub teb chaws tau mus txog 1600 degree.

Gas turbines yog lwm qhov tseem ceeb ntawm kev siv superalloys, thiab lub teeb-lub luag haujlwm roj turbines feem ntau yog siv rau kev tswj hwm lub zog thiab lub zog nkoj. Heavy-duty gas turbines yog cov khoom siv roj turbines tsuas yog siv rau kev sib xyaw ua ke ntawm lub zog hluav taws xob thiab kev cog lus. Qhov kub ntawm cov roj txhaj rau hauv lub impeller los ntawm cov roj turbine yog siab li 1300 degree, yog li lub impeller yuav tsum tau ua los ntawm superalloy. Tam sim no, kuv lub teb chaws siv ntau pua lab nyiaj daus las rau cov khoom siv turbine tuaj txawv teb chaws txhua xyoo. Txoj kev loj hlob zeem muag ntawm domestic gas turbines muab qhov chaw loj heev rau kev siv superalloys.
