Hlau-raws li wrought high-temperature alloys yog workhorses nyob rau hauv ntau industries:
Kev tsim hluav taws xob:
Turbine Blades & Discs nyob rau hauv chav turbines thiab qis-kub theem ntawm roj turbines.
Boiler Tubing, Superheater & Reheater Tubes, thiab cov khoom siv hluav taws xob sib hloov hauv cov roj hluav taws xob fossil.
Automotive:
Turbocharger Housings (Turbine Housings) uas yuav tsum tiv taus cov pa cua kub.
Exhaust Manifolds thiab downpipes.
Industrial Furnaces & Kev kho cua sov:
Radiant Tubes, Muffles, Tais, thiab pob tawb siv hauv carburizing, annealing, thiab lwm yam txheej txheem kho cua sov.
Petrochemical thiab Refining:
Tubing rau cov cua sov coils thiab cov kav dej rau cov txheej txheem kub kub hauv cov catalytic crackers thiab hloov kho.
Cov lus hauv qab no qhia txog cov yam ntxwv tseem ceeb rau kev saib xyuas sai:
| Feature | Kev piav qhia | Qhov zoo |
| Base Element | Hlau (Fe), nrog siab Chromium (Cr) cov ntsiab lus. | Muab tus nqi tsim nyog nrog lub hauv paus oxidation tsis kam. |
| Txoj kev tsim khoom | Thermomechanical Processing (Kub Rolling, Forging). | Ua rau ib tug uniform, nplua-grained qauv nrog zoo ductility thiab toughness. |
| Key Strengtheners | Kev daws teeb meem (Mo, W); Carbides (Cr, Nb, Mo). | Muab qhov sib npaug sib npaug ntawm qhov kub thiab txias zog thiab microstructural stability. |
| Qhov kub thiab txias | Kev ua tau zoo txog ~ 760 ° C (1400 ° F). | Sau qhov sib txawv tseem ceeb ntawm kev ua haujlwm ntawm tus qauv stainless hlau thiab nickel superalloys. |
| Cov txiaj ntsig tseem ceeb | Qhov zoo tshaj plaws sib npaug ntawm kev ua tau zoo, fabricability, thiab nqi. | Qhov kev daws teeb meem zoo tshaj plaws rau ntau qhov kev sib tw kub-kub engineering. |
| Common Alloys & Hom | Austenitic (piv txwv li, 304H, 316H, 321H, 347H); Ferritic (piv txwv li, 446); Los nag-Hardenable (piv txwv li, A-286, 17-4PH). | Muaj ntau txoj kev xaiv rau qhov sib txawv ntawm qhov kub thiab txias, lub zog, thiab corrosion. |
Hauv cov ntsiab lus, Hlau-raws li Wrought High-temperature Alloys yog cov chav kawm tseem ceeb thiab muaj ntau yam ntawm cov ntaub ntawv uas ua rau muaj feem ntau ntawm kev tsim hluav taws xob niaj hnub high-temperature. Lawv txoj kev loj hlob sawv cev rau kev ua kom zoo ntawm tus nqi thiab kev ua tau zoo, ua rau lawv tseem ceeb rau cov ntawv thov xws li tsev neeg lub tsheb mus rau cov chaw tsim hluav taws xob uas muab nws cov hluav taws xob.
