1. Cov ntaub ntawv dab tsi yog them nyob rau hauv cov khoom no?
Teb:
Qhov ntau no suav nrog kev siab siab - Performation - Raws li cov kab sib tshooj thiab pas nrig, tshwj xeeb:
Inconel (piv txwv li, 600, 625, 718) - paub zoo heev {6} lub zog thiab corrosion tsis kam.
Hastelloy c276 - Txaus siab rau oxidizing thiab txo cov neeg sawv cev, acids, thiab chlorides.
Monel 400 -} -}} tooj liab alloy nrog severason thiab alkalis, ntxiv rau cov khoom siv neeg kho kom zoo.
2. Dab tsi yog qhov tseem ceeb ntawm cov khoom siv ntawm cov alloys?
| Hlau | Ntsiab Lus (%) |
|---|---|
| Tsis zoo | Npib tsib xee (NI) 50-72, chromium (CR) 14-23, Mo, NB |
| Hastelloy C276 | Ni tshuav nyiaj, cr 14.5-16.5, Mo 15-17, FE 4-7 |
| Monel 400 | Ni ~ 63, CU 28-34, FE 2.5, MN 1.2 |
Cov kev sib xyaw no muab cov tsis kam ua kom zoo rau ntau hom kev xeb thiab kev kub siab.
3. Dab tsi yog cov cuab yeej siv neeg kho mob uas raug nyob hauv qhov tsis paub tab?
| Hlau | Tensile lub zog (mpa) | Yield zog (mpa) | Elongation (%) | Max pab temp (degree) |
|---|---|---|---|---|
| Tsis zoo | 690 – 1100 | 240 – 720 | 25 – 35 | Mus txog 700 |
| Hastelloy C276 | 690 – 790 | 350 – 400 | 40 | Txog li 1040 |
| Monel 400 | 550 | 240 | 30 – 35 | Txog li 480 |
4. Qhov ntau thiab tsawg thiab cov ntaub ntawv muaj?
Txoj kab uas hla: 3 mm txog li 350 hli (kev cai ntau thiab)
Ntev: tus qauv mus txog 6 meters, kev cai txiav {{1} - ntev muab
Daim Ntawv: Cov kab tuav thiab pas nrig, suav nrog kub dov, txias kos, lossis forged kev xaiv
Deg tas: Dub (raws li - rolled), ci annealed, av, lossis polished
5. Dab tsi yog qhov kev lag luam tseem ceeb thiab cov ntawv thov rau cov alloys?
Aerospace thiab lub hwj chim ntau tiam: Cheebtsam ua kom huv, kev ua kom huv, kev hloov pauv kub (inconel)
Kev Lag Luam: Reactors, Scrubbers, Cov Khoom Siv Hluav Taws Xob (Hastelloy C276)
Tubrog nkoj thiab ntug hiav txwv: Cov Twj Tso Kua Muag, Li Qub, Seasater Dej (Monel 400)
Roj thiab roj: downhole khoom siv, siab - train
Cov ntaub ntawv no muaj kev ua haujlwm zoo dua, muaj zog dua, thiab thermal stability rau cov ntawv thov tseem ceeb.
